20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Chapter 1
Getting Started
The adapter is intended for installation into a PowerFlex 7-Class drive and
is used for network communication. The 20-COMM-C Series B coax
adapter, firmware 2.xxx or later, or 20-COMM-Q Series A fiber adapter,
firmware 2.xxx or later, can also be installed in an External DPI Comms Kit
(20-XCOMM-DC-BASE).
For PowerFlex 750-Series drives, we recommend using the 20-750-CNETC
Coaxial ControlNet option module instead of the 20-COMM-C adapter.
However, this manual does include information on using the 20-COMM-C
or 20-COMM-Q adapter with PowerFlex 750-Series drives—but there are
operating limitations. For details, see Compatible Products
on page 1-3.

Safety Precautions
Please read the following safety precautions carefully.
!
ATTENTION: Risk of injury or death exists. The PowerFlex
drive may contain high voltages that can cause injury or death.
Remove all power from the PowerFlex drive, and then verify
power has been discharged before installing or removing an
adapter.
!
ATTENTION: Risk of injury or equipment damage exists. Only
personnel familiar with drive and power products and the
associated machinery should plan or implement the installation,
start up, configuration, and subsequent maintenance of the
product using an adapter. Failure to comply may result in injury
and/or equipment damage.
!
ATTENTION: Risk of equipment damage exists. The adapter
contains electrostatic discharge (ESD) sensitive parts that can be
damaged if you do not follow ESD control procedures. Static
control precautions are required when handling the adapter. If
you are unfamiliar with static control procedures, see Guarding
Against Electrostatic Damage, publication 8000-4.5.2.
!
ATTENTION: Risk of injury or equipment damage exists. If the
adapter is transmitting control I/O to the drive, the drive may fault
when you reset the adapter. Determine how your drive will
respond before resetting an adapter.
!
ATTENTION: Risk of injury or equipment damage exists.
Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
communication is disrupted or the controller is idle. By default,
these parameters fault the drive. You can set these parameters so
that the drive continues to run, however, precautions should be
taken to verify that the settings of these parameters do not create
a risk of injury or equipment damage. When commissioning the
drive, verify that your system responds correctly to various
situations (for example, a disconnected cable or a controller in
idle state).
!
ATTENTION: Risk of injury or equipment damage exists.
When a system is configured for the first time, there may be
unintended or incorrect machine motion. Disconnect the motor
from the machine or process during initial system testing.
!
ATTENTION: Risk of injury or equipment damage exists. The
examples in this publication are intended solely for purposes of
example. There are many variables and requirements with any
application. Rockwell Automation does not assume responsibility
or liability (to include intellectual property liability) for actual
use of the examples shown in this publication.

Configuring and Verifying Key Drive Parameters
The PowerFlex 7-Class drive can be separately configured for the control
and Reference functions in various combinations. For example, you could
set the drive to have its control come from a peripheral or terminal block
with the Reference coming from the network. Or you could set the drive to
have its control come from the network with the Reference coming from
another peripheral or terminal block. Or you could set the drive to have both
its control and Reference come from the network.
The following steps in this section assume that the drive will receive the
Logic Command and Reference from the network.
1. Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed
Reference to ‘22’ (DPI Port 5).

2. If hard-wired discrete digital inputs are not used to control the drive,
verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and
362 - [Dig In2 Sel] are set to ‘0’ (Not Used).
3. Verify that drive Parameter 213 - [Speed Ref Source] is reporting that
the source of the Reference to the drive is ‘22’ (DPI Port 5).
This ensures that any Reference commanded from the network can be
monitored by using drive Parameter 002 - [Commanded Speed]. If a
problem occurs, this verification step provides the diagnostic capability
to determine whether the drive/adapter or the network is the cause.
Commissioning the Adapter
To commission the adapter, you must set a unique node address on the
network. See Setting the Node Address
on page 3-3 for details.
Important:New settings for some adapter parameters are recognized only
when power is applied to the adapter or it is reset. After you
change parameter settings, cycle power or reset the adapter.
TIP: For PowerFlex 750-Series drives, use drive Parameter 545 -
[Speed Ref A Sel] to set the drive speed Reference:
a. Set the Port field to ‘Port 0 - PowerFlex 75x’.
b. Set the Parameter field to point to the port (slot) in which the

Publication 20COMM-UM003F-EN-P
Setting the Node Address
If the adapter Node Address switches (Figure 2.1) are set to ‘00’ (Program)
the value of Parameter 03 - [CN Addr Cfg] determines the node address.
When in any other combination of positions, the Node Address switches
determine the node address.
1. Set the value of Parameter 03 - [CN Addr Cfg] to a unique node
address.
2. Reset the adapter (see Resetting the Adapter
on page 3-7).
When the node address is correctly configured and the adapter is connected
to an operational network, the NET A status indicator should be steady
green or flashing green.
Setting the I/O
Configuration
The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. (Datalinks allow you to read/write directly to
parameters in the drive using implicit I/O.) A ‘1’ enables the I/O and a ‘0’
disables the I/O.
1. Set the bits in Parameter 13 - [DPI I/O Cfg].
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
2. If a controller is used to control the drive, set adapter Parameters 25 -
[M-S Input] and 26 - [M-S Output] for Master-Slave Hierarchy.
For details, see Setting Master-Slave Hierarchy
on page 3-4.
3. If Logic Command/Reference is enabled, configure the parameters in
the drive to accept the Logic Command and Reference from the adapter.
For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or
700 drive to ‘22’ (DPI Port 5) so that the drive uses the Reference from
the adapter. Also, verify that the mask parameters (for example,
Parameter 276 - [Logic Mask]) in the drive are configured to receive the
desired logic from the adapter. See the documentation for your drive for
details.

4. If you enabled one or more Datalinks, configure parameters in the drive
to determine the source and destination of data in the Datalinks.
When using Datalinks, up to 8 drive [Data In xx] parameters
(300…307) and/or up to 8 [Data Out xx] parameters (310…317) must
be assigned to point to the appropriate drive parameters for your
application. See Chapter 4
for an example.
5. Reset the adapter (see Resetting the Adapter
on page 3-7).
The adapter is ready to receive I/O. You must now configure the adapter to
receive I/O from the master. See Setting Master-Slave Hierarchy
.
Setting Master-Slave
Hierarchy
A hierarchy determines the type of device with which the adapter exchanges
data. In a Master-Slave hierarchy, the adapter exchanges data with a master,
such as a bridge or scanner (1756-CNB/CNBR, 1747-SCNR, and so forth).
1. Enable the desired I/O in Parameter 13 - [DPI I/O Cfg].
See Setting the I/O Configuration
on page 3-3.
2. Set the bits in Parameter 25 - [M-S Input].
This parameter determines the data received from the master by the
drive. A ‘1’ enables the I/O and a ‘0’ disables the I/O.
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
3. Set the bits in Parameter 26 - [M-S Output].
This parameter determines the data transmitted from the drive to the
bridge or scanner. A ‘1’ enables the I/O and a ‘0’ disables the I/O.
Bit 0 is the right-most bit. It is highlighted above and equals ‘1’.
4. Reset the adapter (see Resetting the Adapter
on page 3-7).

The adapter is ready to receive I/O from the master (that is, scanner). You
must now configure the scanner to recognize and transmit I/O to the adapter.
See Chapter
4, Configuring the I/O.
Setting the Reference
Adjustment
A Reference Adjustment is a percent scaling factor for the Reference from
the network. It can be set between 0.00…200.00% to allow the drive’s
Reference to either match the network Reference (equal to 100.00%), scale
below the network Reference (less than 100.00%), or scale above the
network Reference (more than 100.00%).
If the adapter is receiving a Reference, set Parameter 27 - [Ref Adjust] to
the desired scaling factor.
The adjustment takes effect as soon as it is entered.
Setting a Fault Action
By default, when I/O communication is disrupted (for example, a cable is
disconnected) or the controller is idle (in program mode or faulted), the
drive responds by faulting if it is using I/O from the network. You can
configure a different response to these faults:
• Disrupted I/O communication by using Parameter 10 - [Comm Flt
Action]
• An idle controller by using Parameter 11 - [Idle Flt Action]
!
ATTENTION: To guard against equipment damage and/or
personal injury, note that changes to adapter Parameter 27 - [Ref
Adjust] take effect immediately. A drive receiving its Reference
from the adapter will receive the newly scaled Reference,
resulting in a change of speed.

Parameters 10 - [Comm Flt Action] and 11 - [Idle Flt Action]
let you determine the action of the adapter and connected drive if
I/O communication is disrupted or the controller is idle. By
default, these parameters fault the drive. You can set these
parameters so that the drive continues to run, however,
precautions should be taken to verify that the settings of these
parameters do not create a risk of injury or equipment damage.
When commissioning the drive, verify that your system responds
correctly to various situations (for example, a disconnected cable
or faulted controller).

If communication is disrupted and then is re-established, the drive will
automatically receive commands over the network again.
Setting the Fault Configuration Parameters
When setting Parameter 10 - [Comm Flt Action] or 11 - [Idle Flt Action]
to ‘Send Flt Cfg’, the values in the following parameters are sent to the drive
after an I/O communication fault and/or idle fault occurs. You must set
these parameters to values required by your application.
Changes to these parameters take effect immediately. A reset is not
required.
Value Action Description
0 Fault The drive is faulted and stopped. (Default)
1 Stop The drive is stopped, but not faulted.
2 Zero Data The drive is sent ‘0’ values for data. This does not command a stop.
3 Hold Last The drive continues in its present state.
4 Send Flt Cfg The drive is sent the data that you set in the fault configuration parameters
(Parameters 15 - [Flt Cfg Logic] through 24 - [Flt Cfg D2 In]).
Parameter Description
15 - [Flt Cfg Logic] A 16-bit value sent to the drive for Logic Command.
16 - [Flt Cfg Ref] A 32-bit value (0…4294967295) sent to the drive as a Reference or Datalink.

Publication 20COMM-UM003F-EN-P
There are three ways to add the adapter into the I/O configuration:
• Drive Add-on Profiles (RSLogix 5000 software, version 16.00 or later)
• Classic Profile (RSLogix 5000 software, versions 13.00…15.00)
• Generic Profile (RSLogix 5000 software, all versions)
These are described in separate sections below. If your version of RSLogix
5000 software supports drive Add-on Profiles, we recommend that you use
this method.
Using RSLogix 5000 Drive Add-on Profiles, Version 16.00 or Later
When compared to using the RSLogix 5000 Classic Profile (versions
13.00…15.00) or Generic Profile (all versions), the RSLogix 5000 drive
Add-on Profiles provide the following advantages:
• Profiles for specific drives that provide descriptive controller tags for
basic control I/O words (Logic Command/Status and Reference/
Feedback) and Datalinks. Additionally, Datalinks automatically take the
name of the drive parameter to which they are assigned. These profiles
virtually eliminate I/O mismatch errors and substantially reduce drive
configuration time.
• New Drive tab eliminates the need for a separate drive software
configuration tool.
• Drive configuration settings are saved as part of the RSLogix 5000
software, version 16.00 or later, project file (.ACD) and also downloaded
to the controller.
• Drive Add-on Profiles can be updated anytime. When a new drive is
used, or to benefit from new updates for Add-on Profiles, you will need
the newest Add-on Profile update. Go to http://www.ab.com/support/
abdrives/webupdate to download the latest RSLogix 5000 drive Add-on
Profile. To determine your drive Add-on Profile version, see
Allen-Bradley Knowledgebase document #65882.
Add the Drive/Adapter to the I/O Configuration
To transmit data between the bridge and the drive, you must add the drive as
a child device to the parent bridge. In this example, RSLogix 5000 software,
version 20.00 is used with drive Add-on Profile version 4.04.

following buttons at the bottom left of the Module Definition screen:
• Create Database: Creates a database from an online network drive. Clicking
this button displays an RSLinx software RSWho window. Browse to the
online drive (for this example, PowerFlex 70 EC), select it, and click OK. The
database will be uploaded and stored on the computer. Thereafter, close the
Module Definition screen and then re-open it to display the new revision.
• Web Update: When a drive is not available online, opens the Allen-Bradley
Drives Web Updates website to download a specific database file. After
downloading the file, close the Module Definition screen and then re-open it
to display the new revision.
• Match Drive: Use this button when the drive being added to the network
matches the drive profile (revision, rating, configuration settings, and so forth)
of an existing online network drive. Click this button to conveniently create a
duplicate drive profile from the online drive, and automatically load this
identical information into the Module Definition screen. This eliminates the
need to manually enter the information each time a new drive with a
matching profile is added to the network.
Electronic
Keying
Compatible Module. The ‘Compatible Module’ setting for Electronic Keying
ensures that the physical module is consistent with the software configuration
before the controller and bridge make a connection. Therefore, ensure that you
have set the correct revision in this screen. See the online Help for additional
information on this and other Electronic Keying settings. If keying is not required,
select ‘Disable Keying’. Drives do not require keying, and so ‘Disable Keying’ is
recommended.

20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
When a 32-bit parameter is selected for Input Data or Output Data for a
drive with 16-bit Datalinks, two contiguous Datalinks (for example, x1
and x2, where x = A, B, C or D) are automatically assigned as a pair to
represent that parameter. See Datalink examples in the screen shown on
the previous page. For more information on Datalinks, see Using
Datalinks on page 5-11.
On the Module Definition screen, notice that the automatically-assigned
controller tags DriveStatus, OutputFreq, DriveLogicRslt, and
CommandedFreq are always used.
When a Datalink is enabled, the following 20-COMM-C or
20-COMM-Q adapter I/O parameters are automatically set:
– Parameter 13 - [DPI I/O Cfg] turns on the enabled Datalink bit so
the 20-COMM-C or 20-COMM-Q adapter will communicate that

Using the RSLogix 5000 Classic Profile, Versions 13.00…15.00
When compared to using the RSLogix 5000 Generic Profile (all versions),
the RSLogix 5000 Classic Profile provides these advantages:
• Profiles for specific drives (Figure 4.3
) that provide descriptive controller
tags for basic control I/O words (Logic Command/Status and Reference/
Feedback). The controller tags for Datalinks, however, have
non-descriptive UserDefinedData[n] names.
• Improved I/O configuration—no I/O assembly configuration required.
Basic control I/O is defined, but Datalinks still need to be configured/
mapped.
• The Setup tab includes a DriveExecutive icon link to conveniently
launch DriveExecutive software (when installed on computer) to match
the adapter I/O configuration with the controller, and to assign the
Datalink parameters in the drive. This reduces I/O mismatches.
Figure 4.3 Classic Profile Screens for Drives
TIP: Because the RSLogix 5000 Classic Profile has been significantly
improved upon by RSLogix 5000 Drive Add-on Profiles, version 16.00 or
later, we recommend using RSLogix 5000 Drive Add-on Profiles to take
advantage of their benefits (more intuitive, time saving, and less likely to
make I/O configuration errors).
4-18 Configuring the I/O
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
When Datalinks are used, you must enable the desired Datalinks and assign
names to their non-descriptive controller tags. When a Datalink is enabled,
you must set the following adapter I/O parameters:
• Parameter 13 - [DPI I/O Cfg] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will communicate that Datalink’s
information with the drive.
• Parameter 25 - [M-S Input] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will input that Datalink’s
information from the controller.
• Parameter 26 - [M-S Output] turns on the enabled Datalink bit so the
20-COMM-C or 20-COMM-Q adapter will output that Datalink’s
information to the controller.
When using Datalinks, up to 8 drive [Data In xx] parameters (300…307)
and/or up to 8 [Data Out xx] parameters (310…317) must be assigned to
point to the appropriate drive parameters for your application.
Important:To change the I/O Not Responding box in the upper-left of the
RSLogix 5000 window from flashing green to steady green,
and to remove the yellow warning symbols displayed in the
treeview under the I/O Configuration folder and drive profile,
follow the procedure in Use RSNetworx for ControlNet
Software to Save the I/O to the Bridge on page 4-13.
Using the RSLogix 5000 Generic Profile, All Versions
We recommend that you use the basic RSLogix 5000 Generic Profile for
only the following reasons:
• A specific drive profile in other versions of RSLogix 5000 software is
unavailable.
• Users are already familiar with a drive Generic Profile and do not want to
convert an existing project to a Classic Profile, versions 13.00…15.00, or
to a drive Add-on Profile (RSLogix 5000 software, version 16.00 or
later.)
• A project must maintain specific revision level control.
• The controller cannot be taken offline. RSLogix 5000 software, version
16.00 or later, enables the drive Generic Profile to be added while the
controller is online and in the Run mode.

Using the I/O
This chapter provides information and examples that explain how to
control, configure, and monitor a PowerFlex 7-Class drive using the
configured I/O.
About I/O Messaging
On CIP-based networks, including ControlNet, I/O connections are used to
transfer the data which controls the PowerFlex drive and sets its Reference.
I/O can also be used to transfer data to and from Datalinks in PowerFlex
7-Class drives.
The adapter provides many options for configuring and using I/O, including
the following:
• Configuring the size of I/O by enabling or disabling the Logic
Command/Reference and Datalinks
• Setting a Master-Slave hierarchy
Chapter 3
, Configuring the Adapter, and Chapter 4, Configuring the I/O,
discuss how to configure the adapter and controller on the network for these
options. The defines the different options. This chapter discusses how to
use I/O after you have configured the adapter and controller.

5-2 Using the I/O
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Understanding the I/O Image
The terms ‘input’ and ‘output’ are defined from the controller’s point of
view. Therefore, output I/O is data that is produced by the controller and
consumed by the adapter. Input I/O is status data that is produced by the
adapter and consumed as input by the controller. The I/O image will vary
based on the following:
• Size (either 16-bit or 32-bit) of the Reference/Feedback words and
Datalink words used by the drive. To determine the size of the
Reference/Feedback and Datalinks, view adapter Parameters 07 - [Ref/
Fdbk Size] and 08 - [Datalink Size]. For information to access
parameters, see Using the PowerFlex 7-Class HIM to Access
Parameters on page 3-2.
• Configuration of I/O (Parameter 13 - [DPI I/O Cfg]). If all I/O is not
enabled, the image is truncated. The image always uses consecutive
words starting at word 0.
• ControlLogix/CompactLogix Controllers only—The drive profile
used in RSLogix 5000 software (drive Add-on Profile in version 16.00 or
later, Classic Profile in versions 13.00…15.00, or Generic Profile in all
versions).
ControlLogix Controller Image
Because the drive Add-on Profile in RSLogix 5000 software, version 16.00
or later, and the Classic Profile, versions 13.00…15.00, provide descriptive
controller tags, the I/O image (tag size and location) is automatically
configured based on the drive being used. When using the Generic Profile
(page 4-18
) in RSLogix 5000 software, however, controller tags are not
descriptive or defined.
The ControlLogix controller I/O image changes depending on the size of
the drive’s Reference/Feedback and Datalinks, and the number of Datalinks
used. Table 5.A
, Table 5.B, and Table 5.C show the I/O image when using
various PowerFlex drives, and all Datalinks enabled.

20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
When the Reference and Feedback are enabled, and a ControlLogix
controller with a drive Add-on Profile or Classic Profile is used, specific
controller tags are automatically created, sized (16-bit or 32-bit), and placed
in the I/O image.
PowerFlex 70/700/700H and PowerFlex 700L Drives with 700 Control
The Reference/Feedback value is a scaled engineering value; it is not in Hertz
or RPM. The Reference uses a ‘32767’ scale. The ‘32767’ endpoint of the
scale is equal to the value of drive parameter 55 - [Maximum Freq], which
has a default value of 130 Hz. For these drives, default scaling is 0…15123
which is equal to 0…60.0 Hz. This is based on the formula shown below.
Reference/Feedback scaling is limited by drive parameter 82 - [Maximum
Speed]. If the default value of 60 Hz. for parameter 82 - [Maximum Speed] is
changed, the speed Reference/Feedback scaling also changes. To determine
Reference/Feedback scaling, use the following formula:
(Parameter 82 ÷ Parameter 55) * 32767 = Scaling
Using drive parameter 82 and 55 default values, speed Reference/Feedback
scaling is:
(60 Hz ÷ 130 Hz) * 32767 = 15123
Therefore, 0…15123 = 0…60.0 Hz.
If parameter 82 - [Maximum Speed] is changed to 90 Hz, then:
(90 Hz ÷ 130 Hz) * 32767 = 22685
Therefore, 0…22685 = 0…90.0 Hz.
A graphic representation of this Reference/Feedback scaling is shown below.
For PowerFlex 70 drives with enhanced control, firmware 2.xxx or later, or
PowerFlex 700 drives with vector control, firmware 3.xxx or later, drive
parameter 298 - [DPI Ref Select] was added to simplify scaling for the
speed Reference/Feedback. When drive parameter 298 - [DPI Ref Select] is
set to its default ‘0’ (Max Freq), the speed Reference/Feedback scaling is as
shown above. However, when parameter 298 - [DPI Ref Select] is set to ‘1’
(Max Speed), the speed Reference/Feedback scaling is equal to parameter
82 - [Max Speed]:
Parameter 82 = Scaling
Using the parameter 82 default value, speed Reference/Feedback scaling is:
0…32767 = 0…60.0 Hz.

If parameter 82 - [Maximum Speed] is changed to 90 Hz, then:
90 Hz = 32767
Speed Feedback uses the same scaling as the speed Reference.
PowerFlex 700S and PowerFlex 700L Drives with 700S Control
The Reference/Feedback value is:
32767 = Base Motor Speed
The base speed is set using drive parameter 4 - [Motor RPM]. To set a speed
Reference/Feedback above base speed, a value greater than 32767 must be
entered.
For 16-bit processors, such as PLC-5 and SLC 500 controllers, the data
requires manipulation to set a speed Reference above 32767 or below
-32767. Please see the PowerFlex 700S AC Drives Phase II Control
Reference Manual, publication PFLEX-RM003, in the Chapter 1
‘Communications’ section. Then go to the ‘PLC 5 or SLC System’
subsection and see the ‘Reference/Feedback Programming’ sub-subsection.
PowerFlex 753/755 Drives
The Reference/Feedback value is Hz x 1000 or RPM x 1000. Drive
parameter 300 - [Speed Units] determines whether the scaling is Hz or
RPM. The default scaling is Hz, where 0…60,000 equates to 0…60.000 Hz.
When parameter 300 is set to RPM, then 0…1,765,000 equates to
0…1765.000 RPM.
For 16-bit processors, such as PLC-5 and SLC 500 controllers, the data
requires manipulation to set a speed Reference above 32767 or below
-32767. Please see the PowerFlex 700S AC Drives Phase II Control
Reference Manual, publication PFLEX-RM003, in the Chapter 1
‘Communications’ section. Then go to the ‘PLC 5 or SLC System’
subsection and see the ‘Reference/Feedback Programming’ sub-subsection.
TIP: For PowerFlex 700 drives with vector control, firmware 3.xxx or later,
parameter 299 - [DPI Fdbk Select] enables you to select the feedback data
coming from the drive over DPI. The default is ‘Speed Fdbk’ in Hz or RPM
determined by parameter 079 - [Speed Units]. The data selection for
parameter 299 is also displayed on the 1st line of the HIM and on
DriveExplorer and DriveExecutive software screens in the drive status area
of the screen.

The Reference/Feedback value is:
25000 = Maximum Reference Speed
The maximum Reference speed is set using drive parameter 45 - [Max Ref
Speed].
Using Datalinks
A Datalink is a mechanism used by PowerFlex drives to transfer data to and
from the controller. Datalinks allow a drive parameter value to be read or
written without using an Explicit Message. When enabled, each Datalink
occupies two 16-bit or 32-bit words in both the input and output image. Use
adapter Parameter 08 - [Datalink Size] to determine whether the drive
uses 16-bit or 32-bit words for Datalinks.
Rules for Using Datalinks
• Each set of Datalink parameters in a PowerFlex drive can be used by
only one adapter. If more than one adapter is connected to a single drive,
multiple adapters cannot use the same Datalink.
• Parameter settings in the drive determine the data passed through the
Datalink mechanism. See the documentation for your drive.
• When you use a Datalink to change a value, the value is not written to
the Nonvolatile Storage (NVS) memory. The value is stored in volatile
memory and lost when the drive loses power. Thus, use Datalinks when
you need to change a value of a parameter frequently.
Datalink Scaling
PowerFlex 70/700/700H Drives and PowerFlex 700L Drives with 700 Control
When using RSLogix 5000 software, version 16.00 or later, Datalink
scaling is done automatically. However, when using RSLogix 5000
software, version 15.00 or earlier—or when using a PLC-5 or SLC 500
controller—Datalink scaling is not automatic and uses whole numbers
(INTs or DINTs). See the drive documentation to determine the unit
resolution for the associated parameter Datalink. For example, PowerFlex
700VC drive parameter 3 - [Output Current] has a 0.1 unit resolution.
Because Datalink scaling uses whole numbers, the Output Current value is
multiplied by 10 in the adapter and then sent over the network. Suppose the
actual Output Current value is 35.5 amps. Reading the associated parameter
Datalink received by the controller, the value would be 355. By using ladder
logic, divide the value by 10 in the controller to get the correct scaling. See
the drive documentation to determine if the Datalink parameter is a 16-bit or
32-bit parameter.

PowerFlex 700S, PowerFlex 700L with 700S Control, PowerFlex 753/755, and
PowerFlex Digital DC Drives
When using RSLogix 5000 software, version 16.00 or later, Datalink
scaling is done automatically. However, when using RSLogix 5000
software, version 15.00 or earlier—or when using a PLC-5 or SLC 500
controller—Datalinks require scaling in the following way. Parameters are
either 16-bit or 32-bit integers or REALs. When the parameter is a 32-bit
integer, the data needs to be copied using a COP command to a DINT tag.
(Because PLC-5 and SLC 500 controllers do not support 32-bit integers, the
data must be separated into two 16-bit integers.) When the parameter is a
REAL, the data needs to be copied using a COP command to a REAL tag.
See subsequent sections in this chapter for ladder logic examples. See the
drive documentation to determine if the Datalink parameter is a 16-bit or
32-bit integer parameter, or a REAL parameter.
Using 16-Bit Datalinks to Read/Write 32-Bit Parameters
This subsection only pertains to PowerFlex 70 (standard or enhanced
control), PowerFlex 700 (standard control), and PowerFlex 700H drives
which use 16-bit Datalinks. To read or write a 32-bit parameter using 16-bit
Datalinks, typically both Datalinks of a pair (A, B, C, D) are set to the same
32-bit parameter. For example, to read parameter 10 - [Elapsed Run Time]
in a PowerFlex 70 drive, both Datalink A1 Out (Parameter 310) and
Datalink A2 Out (Parameter 311) are set to ‘10’. Datalink A1 Out will
contain the least significant word (LSW) and Datalink A2 Out will contain
the most significant word (MSW).
32-bit data is stored in binary as follows:
In this example, the parameter 10 - [Elapsed Run Time] value of 6553.9 Hrs
is read as ‘6553.9’ in Datalink A1 Out (Parameter 310) and Datalink A2
Out (Parameter 311).

Regardless of the Datalink combination, Datalink x1 Out will always
contain the LSW and Datalink x2 Out will always contain the MSW. In the
following example, the PowerFlex 70 drive parameter 242 - [Power Up

Example Ladder Logic
Program Information
The example ladder logic programs in the sections of this chapter are
intended for and operate PowerFlex 7-Class drives.
Functions of the Example Programs
The example programs enable you to do the following:
• Receive Logic Status information from the drive.
• Send a Logic Command to control the drive (for example, start, stop).
• Send a Reference to the drive and receive Feedback from the drive.
• Send/receive Datalink data to/from the drive.
Logic Command/Status Words
These examples use the Logic Command word and Logic Status word for
PowerFlex 70/700 drives. Information for PowerFlex 750-Series drives has
been added to examples where applicable. See Appendix
D to view details.
The definition of the bits in these words may vary if you are using a
different DPI drive. See the documentation for your drive.

Example
You can use any of RSLogix 5000 software versions to create the ladder
logic. These are described in separate sections below. If your version of
RSLogix 5000 software supports drive Add-on Profiles, we recommend that
you use this method.
Creating Ladder Logic Using the RSLogix 5000 Drive Add-on Profiles,
Version 16.00 or Later
Because the drive Add-on Profile automatically created descriptive controller
tags (Figure 4.2
) for the entire I/O image in Chapter 4, you can use these tags
to directly control and monitor the drive without creating any ladder logic
program. However, if you intend to use Human Machine Interface devices
(PanelView, and so forth) to operate the drive and view its status, you will
need to create descriptive user-defined Program tags (Figure 5.1
) and a ladder
logic program that will pass the Controller tag data to the Program tags.
Figure 5.1 ControlLogix Program Tags for Drive Add-on Profile Ladder Logic
Program Example
An example ladder logic program that uses the automatically-created
descriptive Controller tags and passes their data to the user-defined Program
tags is shown in Figure 5.2
and Figure 5.3. Note that the prefix for the drive
Controller tags is determined by the name assigned when configuring the
I/O (Chapter
4).
Depending on the drive being used, see one of the following subsections for
information on speed Reference and Feedback scaling.

Creating Ladder Logic Using the RSLogix 5000 Classic Profile,
Versions 13.00…15.00
Because the RSLogix 5000 Classic Profile has been significantly improved
upon by RSLogix 5000 drive Add-on Profiles, version 16.00 or later, we
recommend using the RSLogix 5000 drive Add-on Profiles to take
advantage of their benefits (more intuitive, time saving, and less likely to
make ladder logic program errors).

In this example, the 20-COMM-C or 20-COMM-Q adapter/20-750-20COMM Communication Carrier Card is installed in Port 6, and a 24V I/O
module is installed in Port 5. Also, Data In B2…D2 (Parameters 898…902) and Data Out B2…D2 (Parameters 908…912) are enabled, but not
used.
TIP: Data In parameters are inputs into the drive that come from controller
outputs (for example, data to write to a drive parameter). Data Out
parameters are outputs from the drive that go to controller inputs (for
example, data to read a drive parameter).

Controller Tags
When you add the adapter and drive to the I/O configuration (Chapter 4
),
RSLogix 5000 software automatically creates generic (non-descriptive)
controller tags for them. In this example program, the following controller
tags are used.

For PowerFlex 750-Series drives, the destination tag can be a REAL or
DINT. Make the destination tag the same data type as the parameter being
read. For information on Datalink scaling, see page 5-12
.
TIP: When using a drive that has 16-bit Datalinks (PowerFlex 70,
PowerFlex 700, and PowerFlex 700H drives) to transfer a 32-bit parameter,
two contiguous drive Datalink parameters (for example, Data Out A1/A2,
B1/B2, and so forth) are required. To determine if a parameter is a 32-bit
parameter, see the Parameter section in the drive documentation and look
for a symbol in the ‘No.’ column. (All parameters in PowerFlex 700
Series B drives are 32-bit parameters.) For example, parameter 3 - [Output
Current] in a PowerFlex 70 EC drive is a 32-bit parameter. When using a
drive that has 32-bit Datalinks (PowerFlex 700 VC, PowerFlex 700S, and
PowerFlex 750-Series drives), only one drive Datalink parameter is required
to transfer any parameter.

Publication 20COMM-UM003F-EN-P
Understanding PLC-5 Controller Data Table Addresses
Because the PLC-5 controller is a 16-bit platform and is used with the
32-bit 20-COMM-C or 20-COMM-Q adapter, the data will be transposed
from the least-significant word (LSW) to the most-significant word (MSW)
in the controller.
When the I/O was configured (Chapter 4
), two available data table
addresses (N9:0 for input data and N10:0 for output data) were used.
Figure 5.12
shows the data file address structure for this example.
Figure 5.12 Data File Table for Example Ladder Logic Program
Depending on the drive, Table 5.J, Table 5.K, Table 5.L, Table 5.M,
Table 5.N
, or Table 5.O show the I/O definitions as they relate to the N9:0
and N10:0 data table addresses in Figure 5.12
being used in this example.
TIP: When using a drive that has 16-bit Datalinks (PowerFlex 70,
PowerFlex 700, and PowerFlex 700H drives) to transfer a 32-bit parameter,
two contiguous drive Datalink parameters (for example, Data Out A1/A2,
B1/B2, and so forth) are required. To determine if a parameter is a 32-bit
parameter, see the Parameter section in the drive documentation and look
for a symbol in the ‘No.’ column. (All parameters in PowerFlex 700
Series B drives are 32-bit parameters.) For example, parameter 3 - [Output
Current] in a PowerFlex 70 EC drive is a 32-bit parameter. When using a
drive that has 32-bit Datalinks (PowerFlex 700 VC, PowerFlex 700S, and
PowerFlex 750-Series drives), only one drive Datalink parameter is required
to transfer any parameter.

With any drive, you can use the controller data table addresses to directly
control and monitor the drive without creating any ladder logic program.
However, if you intend to use Human Machine Interface devices
(PanelView, and so forth) to operate the drive and view its status, you will
need to create descriptive controller data table addresses (Table 5.P
and
Table 5.Q
) and a ladder logic program that will pass that data to the data
table addresses used for messaging.
Table 5.P PLC-5 and Program Data Table Address Descriptions for Example Logic
Status/Feedback Ladder Logic Program
Table 5.Q Program and PLC-5 Data Table Address Descriptions for Example Logic

An example ladder logic program that uses these descriptive controller data
table addresses and passes their data to the descriptive program data table
addresses is shown in Figure 5.13

In this example, the 20-COMM-C or 20-COMM-Q adapter/20-750-20COMM Communication Carrier Card is installed in Port 6, and a 24V I/O
module is installed in Port 5. Also, Data In B2…D2 (Parameters 898…902) and Data Out B2…D2 (Parameters 908…912) are enabled, but not
used.
TIP: Data In parameters are inputs into the drive that come from controller
outputs (for example, data to write to a drive parameter). Data Out
parameters are outputs from the drive that go to controller inputs (for
example, data to read a drive parameter).
Using the I/O 5-41
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Understanding SLC 500 Controller Data Table Addresses
Because the SLC 500 controller is a 16-bit platform and is used with the
32-bit 20-COMM-C or 20-COMM-Q adapter, the data will be transposed
from the least-significant word (LSW) to the most-significant word (MSW)
in the controller.
When the I/O was configured (Chapter 4
), two available default memory
addresses (M1:e.3 for input data and M0:e.3 for output data) were used.
However, because memory addresses cannot be used to display real data,
COP instructions will be used in this example to convert these addresses to
N data table addresses. With this conversion, the M1:e.3 address will
become N9:0 and the M0:e.3 address will become N10:0.
Figure 5.17
shows an example ladder logic program to convert memory
addresses to N data table addresses.
Figure 5.17 SLC 500 Example Ladder Logic Program to Convert Memory Addresses
After the conversion, Figure 5.18 shows the entire data file address structure
for this example.
TIP: When using a drive that has 16-bit Datalinks (PowerFlex 70,
PowerFlex 700, and PowerFlex 700H drives) to transfer a 32-bit parameter,
two contiguous drive Datalink parameters (for example, Data Out A1/A2,
B1/B2, and so forth) are required. To determine if a parameter is a 32-bit
parameter, see the Parameter section in the drive documentation and look
for a symbol in the ‘No.’ column. (All parameters in PowerFlex 700
Series B drives are 32-bit parameters.) For example, parameter 3 - [Output
Current] in a PowerFlex 70 EC drive is a 32-bit parameter. When using a
drive that has 32-bit Datalinks (PowerFlex 700 VC, PowerFlex 700S, and
PowerFlex 750-Series drives), only one drive Datalink parameter is required
to transfer any parameter.
32
TIP: In the ladder logic COP instructions, the number following the colon
in the #M1 and #M0 addresses is the slot number in which the scanner
resides. For example, if the 1747-SCNR scanner is in slot 3, then the #M1
address becomes #M1:3.3 and the #M0 address becomes #M0:3.3.

To operate any drive and view its status using the data table addresses,
Human Machine Interface devices (PanelView, and so forth), or a ladder
logic program, you will need to create descriptive controller data table
addresses (Table 5.X
and Table 5.Y) and a ladder logic program that will
pass the controller address data to the program data table addresses.
Table 5.X SLC 500 and Program Data Table Address Descriptions for Example Logic
Status/Feedback Ladder Logic Program
Table 5.Y Program and SLC 500 Data Table Address Descriptions for Example Logic
Command/Reference Ladder Logic Program
Important:In addition to the Run mode for the processor, the scanner also
has its own Run mode. To change the scanner mode from IDLE
to RUN, set Bit 10 in data table address O:e.0, where e = the
scanner slot number. For this example, we set Bit 10 in data
table address O:1.0.
An example ladder logic program that uses these descriptive controller data
table addresses and passes their data to the descriptive program data table
addresses is shown in Figure 5.19

Using Explicit Messaging
This chapter provides information and examples that explain how to use
Explicit Messaging to configure and monitor the adapter and connected
PowerFlex 7-Class drive or PowerFlex 750-Series drive.
Important:When used in a PowerFlex 750-Series drive, the 20-COMM-C
or 20-COMM-Q adapter must have firmware 3.001 or later to
support explicit messaging to drive parameters (Port 0).
Furthermore, the adapter requires firmware 3.002 or later for
explicit messaging to parameters of peripherals in drive Ports
1…14.
Refer to Chapter 5
for information about the I/O Image, using Logic
Command/Status, Reference/Feedback, and Datalinks.

!
ATTENTION: Risk of equipment damage exists. If Explicit
Messages are programmed to write parameter data to Nonvolatile
Storage (NVS) frequently, the NVS will quickly exceed its life
cycle and cause the drive to malfunction. Do not create a program
that frequently uses Explicit Messages to write parameter data to
NVS. Datalinks do not write to NVS and should be used for
frequently changed parameters.

About Explicit Messaging
Explicit Messaging is used to transfer data that does not require continuous
updates. With Explicit Messaging, you can configure and monitor a slave
device’s parameters on the network.
Important:When an explicit message is performed, by default no
connection is made because it is an ‘unconnected’ message.
When timing of the message transaction is important, you can
create a dedicated message connection between the controller
and drive by checking the ‘Connected’ box on the
Communications tab message configuration screen during
message setup. These message connections are in addition to
the I/O connection. However, the trade off for more message
connections is decreased network performance. If your
application cannot tolerate this, we recommend to not check the
‘Connected’ box.
Important:PowerFlex 7-Class and PowerFlex 750-Series drives have
explicit messaging limitations. Table 6.A
shows the ControlNet
Object Class code compatibilities for these drives.

Performing Explicit
Messages
There are five basic events in the Explicit Messaging process. The details of
each step will vary depending on the type of controller being used. See the
documentation for your controller.
Important:There must be a request message and a response message for all
Explicit Messages, whether you are reading or writing data.
Figure 6.1 Explicit Message Process
For information on the maximum number of Explicit Messages that can be
executed at a time, see the documentation for the scanner or bridge and/or
controller that is being used.
Event Description
➊
You format the required data and set up the ladder logic program to send an Explicit
Message request to the scanner or bridge module (download).
➋
The scanner or bridge module transmits the Explicit Message Request to the slave device
over the network.
➌
The slave device transmits the Explicit Message Response back to the scanner. The data is
stored in the scanner buffer.
➍
The controller retrieves the Explicit Message Response from the scanner’s buffer (upload).
➎
The Explicit Message is complete.

PowerFlex 700S drive, Output Current is a floating point number requiring the Data Type field to be set to ‘REAL’ when
creating the controller tag. See the drive documentation to determine the size of the parameter and its data type (16-bit or
32-bit integer or REAL).

ControlLogix Controller Example Ladder Logic Program to Write a Single Parameter
Using RSLogix 5000 Software, Version 15.00 or Later
A Parameter Write message is used to write to a single parameter. This
write message example writes a value to parameter 140 - [Accel Time 1] in
a PowerFlex 7-Class drive.
Important:Parameter Object Class code 0x0F is not supported in
PowerFlex 750-Series drives. To do a single parameter write,
follow the RSLogix 5000 software (any version) single write
example on page 6-10
.
Table 6.D Example Controller Tags to Write a Single Parameter
Figure 6.6 Example Ladder Logic to Write a Single Parameter
Important:If the explicit message single write must be written
continuously, use DPI Parameter Object Class code 0x93 or
Host DPI Parameter Object Class code 0x9F and attribute A (10
decimal; see page 6-11
). This writes to RAM—not NVS
(EEPROM) memory. This example single write message using
Class code F writes to NVS. Over time, continuous writes will
exceed the EEPROM life cycle and cause the drive to
malfunction.

(10 decimal) will write the parameter value to temporary memory, which deletes the parameter value after the drive is power cycled. When frequent write messages
are required, we recommend using the ‘A’ (10 decimal) setting.

In this example, we are reading five parameters. Each parameter being read requires an array of three INT registers. Therefore, a
controller tag was created with its Data Type field set to ‘INT[15]’. Also, the Source Length field on the Message Configuration
screen must correspond to the selected Data Type in bytes (for this example, 30 bytes for an INT[15] array). Scattered read
messages always assume that every parameter being read is a 32-bit integer, regardless of its actual data type. Maximum length
is 132 bytes or 66 words which equates to 22 parameters. For parameter numbering, see DPI Parameter Object
on page C-16
(Class code 0x93) or Host DPI Parameter Object

on page C-30 (Class code 0x9F) to determine the instance number. For example, to read
parameter 4 of a peripheral in Port 5 of a PowerFlex 750-Series drive, the instance would be 21504 + 4 = 21508 or 5404 (Hex).

In this example, Output Current is a 32-bit integer parameter requiring the Size in Elements field to be set to ‘2’. If the parameter being
read is a 16-bit integer, the Size in Elements must be set to ‘1’. When using a PowerFlex 700S or PowerFlex 750-Series drive, Output
Current is a REAL (floating point) parameter. You must still write this data to an integer file with Size in Elements set to ‘2’. The following
page shows ladder logic to convert the data into a floating point.

Setting the Attribute value to ‘9’ will write the parameter value to the drive’s Nonvolatile Storage (EEPROM) memory, which retains
the parameter value even after the drive is power cycled. Important: When set to ‘9’, the EEPROM may quickly exceed its life cycle
and cause the drive to malfunction. Setting the Attribute value to ‘A’ will write the parameter value to temporary memory, which
deletes the parameter value after the drive is power cycled. When frequent write messages are required, we recommend using the
‘A’ setting.

20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
SLC 500 Controller
Examples
The CIP messaging method provides two ways to perform explicit
messaging:
• Read/Write Parameter Service simplifies setup by requiring less data to
be entered in message configuration screens. However, the Read/Write
Parameter Service can only be used to perform single parameter read or
single parameter write explicit messages. (Multiple parameter reads or
writes must be performed using the Generic Get/Set Attribute Service
described below.)
Important:When performing a Write Parameter message, the data will
always be written to the drive’s Nonvolatile Storage (NVS).
Continuous NVS writes may damage the drive’s EEPROM.
If continuous writes are necessary, use the Generic Set
Attribute Single Service and attribute 10 (see page 6-51
).
• Generic Get/Set Attribute Service requires more setup data to be entered
in message configuration screens, but can be used to perform single
parameter read or write explicit messages or multiple parameter read or
write explicit messages. Also, the Generic Set Attribute Service offers
the choice of writing the data to the drive’s Nonvolatile Storage (NVS) or
the drive’s Random Access Memory (RAM; for Generic Set Attribute
Single service only, see page 6-51
). Note that when selecting the data to
be written to RAM, the data will be lost if the drive loses power.
For supported classes, instances, and attributes, see Appendix
C,
ControlNet Objects
.
Block transfer or CEM (ControlNet Explicit Message) instructions can be
used to perform explicit messaging. Since CEM instructions are easier to
configure and perform more efficiently, they are used for these examples.
Important:RSLogix 500 software, version 7.10 or later, and a SLC 5/03,
SLC 5/04, or SLC 5/05 controller, Series C with firmware
version 10.00 or later, are required to use CEM instructions.

In this example, Output Current is a 32-bit integer parameter requiring the Size in Words field to be set to ‘2’. If the parameter being read is a 16-bit
integer, the Size in Words must be set to ‘1’. When using a PowerFlex 700S or PowerFlex 750-Series drive, Output Current is a floating point number
requiring the Size in Words to be set to ‘2’. See the drive documentation to determine the size of the parameter and its data type (16-bit or 32-bit integer

SLC 500 Controller Example Ladder Logic Program to Write a Single Parameter
Using Read/Write Parameter Service
A Write Parameter message is used to write to a single parameter. This
write message example writes a value to parameter 140 - [Accel Time 1] in
a PowerFlex 7-Class drive.
Important:Parameter Object Class code 0x0F is not supported in
PowerFlex 750-Series drives. To do a single parameter write,
follow the SLC 500 (Generic Attribute Service) single write
example on page 6-51
.
Figure 6.54 Example Ladder Logic to Write a Single Parameter
Important:If the explicit message single write must be written
continuously, use the Generic Set Attribute Single service and
attribute A (10 decimal; see page 6-51
). This writes to RAM—
not NVS (EEPROM) memory. This example single write
message using Class code F writes to NVS. Over time,
continuous writes will exceed the EEPROM life cycle and
cause the drive to malfunction.

Setting the Attribute value to ‘9’ will write the parameter value to the drive’s Nonvolatile Storage (EEPROM) memory, which retains the parameter value even
after the drive is power cycled. Important: When set to ‘9’, the EEPROM may quickly exceed its life cycle and cause the drive to malfunction. Setting the

When frequent write messages are required, we recommend using the ‘A’ (10 decimal) setting.

In this example, Accel Time 1 is a 16-bit integer parameter requiring the Size in Words field to be set to ‘1’. If the parameter being written to is a 32-bit

The PowerFlex 750-Series drive uses 32-bit integer and REAL parameters.
A COP command must be used to copy the N60 integer array to a 16-bit
integer or floating tag. Figure 6.74
shows the ladder logic used for this
example. If the parameter data type is a 32-bit integer, the data remains split
into two 16-bit integers because there are no 32-bit integers in the SLC 500
controller. If the parameter data type is a REAL, then the destination tag is a
floating point. In this case, the value must first be swapped with the high
and low 16-bit integers, and then the two integers copied (COP) into a
floating point address. See the drive documentation to determine the
parameter data type (32-bit integer or REAL).

In this example, we are writing to five parameters. Each parameter being written to requires three contiguous 16-bit words. Scattered write messages
always assume that every parameter being written to is a 32-bit integer, regardless of its actual data type. The data structure format is the same as
shown on page 6-53

Viewing and Clearing
Events
The adapter has an event queue to record significant events that occur in the
operation of the adapter. When such an event occurs, an entry is put into the
event queue. You can view the event queue with any of these drive
configuration tools:
• LCD PowerFlex 7-Class HIM
• Connected Components Workbench software, version 1.02 or later
• DriveExplorer software, version 2.01 or later
• DriveExecutive software, version 1.01 or later
The event queue can contain up to 32 entries. Eventually the event queue
will become full, since its contents are retained through adapter resets. At
that point, a new entry replaces the oldest entry. Only an event queue clear
operation or adapter power cycle will clear the event queue contents.
Resetting the adapter to defaults has no effect on the event queue.

Using the Adapter in a DPI External Comms Kit
(20-XCOMM-DC-BASE)
This chapter provides information and examples that explain how to use the
adapter in a DPI External Comms Kit (20-XCOMM-DC-BASE).
The adapter is typically installed in the internal communication slot on the
PowerFlex 7-Class drive. However, an externally-mounted adapter may be
desired when:
• The PowerFlex drive is already connected to an existing network, such as
Remote I/O, and a second network is desired for a DriveExplorer or
DriveExecutive software tool, data collection, and so forth.
• The PowerFlex drive is remotely located next to some I/O devices that
also need to be networked. The DPI External Comms Kit has an option
slot for general-purpose network I/O that a controller can use. Both the
drive and I/O devices are handled as one node on the network to reduce
the network node count.
Installing the Adapter
The adapter can be installed in a DPI External Comms Kit.

I/O Board Option
(20-XCOMM-IO-OPT1)
The I/O Board option, when installed in the DPI External Comms Kit, can
be used with only a Series B adapter, firmware revision 3.xxx or later. The
I/O Board provides six DC inputs and two Relay outputs for use by a
controller on the network.
Figure 8.2 I/O Connector Function Descriptions
For more information, see the I/O Board Option Installation Instructions,
publication 20COMM-IN002.
Understanding the I/O Image
(Drive + I/O Option)
The data for the optional I/O Board is sent over the I/O connection using
Datalink D. When the optional I/O Board is installed in the DPI External
Comms Kit, Datalink D is dedicated only for this function and is not
available for other uses. When the adapter detects the presence of the
optional I/O Board, the I/O image is modified as shown in Figure 8.3
.

The data from the I/O Board is loaded into the Datalink word starting with
bit 0 of Datalink D1 and concluding with bit 14. Bit 15 of Datalink D1 is
reserved as an input valid Status flag. When the input data is valid, bit 15 =
1.
For example, for the 20-XCOMM-IO-OPT1, the digital inputs and digital
outputs are mapped as shown in Figure 8.4
and Figure 8.5 respectively.
Figure 8.4 I/O Board Option Digital Input Mapping
Figure 8.5 I/O Board Option Digital Output Mapping
Important:On power-up or reset, the outputs will be in a ‘non-activated’
state.
Configuring the Adapter to
Use the Optional I/O Data
To configure the adapter to use the optional I/O Board, Parameters 13 -
[DPI I/O Cfg], 25 - [M-S Input], and 26 - [M-S Output] must be set. To
send input/output data from the optional I/O board to the network, do the
following:
• Turn on bit 4 (1xxxx) in Parameter 25 - [M-S Input]
• Turn on bit 4 (1xxxx) in Parameter 26 - [M-S Output]
• Turn off bit 4 (0xxxx) in Parameter 13 - [DPI I/O Cfg]
Setting the Datalink D bit 4 in the M-S Input and M-S Output parameters
directs the communication adapter to send Datalink D back to the controller.
Turning off bit 4 in the DPI I/O Cfg parameter directs the communication
adapter to not send Datalink D data back to the drive. For more information
on I/O Messaging and Configuring Datalinks, see Chapter 5
, Using the I/O.
If the I/O Board Fault Action Jumper (JMP1) is set to the Fault
Configurable position, Parameter 23 - [Flt Cfg D1 In] is used to set the
states of the outputs when the I/O Board takes its Fault Action. For details
on setting the Fault Action jumper, see the I/O Board Option Installation
Instructions, publication 20COMM-IN002.

N-File Description
N41 This N-file lets you read and write control I/O messages. You can write control I/O
messages only when all of the following conditions are true:
• The adapter is not receiving I/O from a scanner. For example, there is no scanner on
the network, the scanner is in idle (program) mode, the scanner is faulted, or the
adapter is not mapped to the scanner.
• The adapter is not receiving peer I/O from another adapter.
• The value of N42:3 is set to a non-zero value.

N-File Description
N150…N199 These N-files let you read and write parameter values in DPI Port 0 (the host
PowerFlex drive) as 32-bit double words. You can interpret the data in various ways
(for example, 32-bit real, 32-bit integer) To read a parameter, you need to send a
message with two elements. For example, to read parameter 1, read two elements
beginning at N150:2. As another example, to read parameters 2…6, read ten
elements beginning at N150:4.

20 Extended Parameter
Reference
0 = Not an Extended Parameter Reference
1 = Extended Parameter Reference
An Extended Parameter Reference contains a reference to another parameter. The value is
formatted the same as an analog mode Indirect Selector parameter (SSpppp, where SS =
slot number of device to which this Extended Parameter Reference is pointing, and pppp =
number of the parameter or diagnostic item to which this Extended Parameter Reference is
pointing). Note that an Extended Parameter Reference can only select parameters unlike
an Indirect Selector. An Extended Parameter Reference could be used to configure a
Datalink or show the source of a Reference (among other uses).
21 Uses Rating Table Object This parameter has rating-dependent defaults and limits that can be obtained from the
Rating Table Object. The Offline Read Full will include the default value for the smallest
rating and limits that will accommodate the full range of values allowed in the family of
devices using this particular combination of Family Code and Config Code. The Online
Read Full will include the rating-dependent default and limit values for this particular
combination of Family Code, Config Code, and Rating Code.
22 Writable Referenced
Parameter
This bit must be zero unless the parameter is an Extended Parameter Reference. If the
parameter is an Extended Parameter Reference, then:
0 = The referenced parameter may be read-only or writable.
1 = The referenced parameter must always be writable (including while running).
23 Disallow Zero This bit must be zero unless the parameter is an Indirect Selector or Extended Parameter
Reference. If the parameter is an Indirect Selector or Extended Parameter Reference, then:
0 = Allow zero
1 = Disallow zero
If this bit is cleared (indicating that a value of zero is allowed), the device must support the
‘Zero Text’ parameter attribute so that a software tool or HIM can obtain text from the Zero
Text parameter attribute.
If this bit is set (indicating that a value of zero is disallowed), a software tool or HIM will not
allow the user to enter a value of zero.
24 Datalink Out This bit is used by offline tools and indicates that this is a Datalink Out parameter. Bit 20
must also be set.
25 Datalink In This bit is used by offline tools and indicates that this is a Datalink In parameter. Bits 20 and
22 must also be set.
26 Not Writable While IO Active This parameter cannot be written if the I/O data being exchanged between the Host and the
peripheral is valid.

Common Services
Object-Specific Services
The table below lists the parameters for the Get_Attributes_Scattered and
Set_Attributes_Scattered object-specific service.
27 Command Parameter This parameter commands the drive to take an action, such as ‘Reset Defaults’ or
‘Autotune’, and then returns to a value of zero. Offline software tools will not allow setting
this parameter to anything other than a value of zero. If an offline file contains a Command
Parameter with a non-zero value, the offline software tool will change the value to zero.
Note that command parameters cannot have values that do not return to zero.
28 Current Value Is Default This bit identifies a parameter that will not change if a ‘Reset Defaults’ is commanded. For
example, if a drive contains a Language parameter that is set to German, setting defaults
will leave the parameter set to German. Likewise, if the parameter is set to French, setting
defaults will leave the parameter set to French.
29 Use Zero Text If the ‘Disallow Zero’ bit is set, this bit must be cleared. If the ‘Disallow Zero’ bit is cleared,
then:
0 = Use Disabled Text parameter class attribute.
1 = Use Zero Text parameter instance attribute.

20 Extended Parameter
Reference
0 = Not an Extended Parameter Reference
1 = Extended Parameter Reference
An Extended Parameter Reference contains a reference to another parameter. The value is
formatted the same as an analog mode Indirect Selector parameter (SSpppp, where SS =
slot number of device to which this Extended Parameter Reference is pointing, and pppp =
number of the parameter or diagnostic item to which this Extended Parameter Reference is
pointing). Note that an Extended Parameter Reference can only select parameters unlike
an Indirect Selector. An Extended Parameter Reference could be used to configure a
Datalink or show the source of a Reference (among other uses).
21 Uses Rating Table Object This parameter has rating-dependent defaults and limits that can be obtained from the
Rating Table Object. The Offline Read Full will include the default value for the smallest
rating and limits that will accommodate the full range of values allowed in the family of
devices using this particular combination of Family Code and Config Code. The Online
Read Full will include the rating-dependent default and limit values for this particular
combination of Family Code, Config Code, and Rating Code.
22 Writable Referenced
Parameter
This bit must be zero unless the parameter is an Extended Parameter Reference. If the
parameter is an Extended Parameter Reference, then:
0 = The referenced parameter may be read-only or writable.
1 = The referenced parameter must always be writable (including while running).
23 Disallow Zero This bit must be zero unless the parameter is an Indirect Selector or Extended Parameter
Reference. If the parameter is an Indirect Selector or Extended Parameter Reference, then:
0 = Allow zero
1 = Disallow zero
If this bit is cleared (indicating that a value of zero is allowed), the device must support the
‘Zero Text’ parameter attribute so that a software tool or HIM can obtain text from the Zero
Text parameter attribute.
If this bit is set (indicating that a value of zero is disallowed), a software tool or HIM will not
allow the user to enter a value of zero.
24 Datalink Out This bit is used by offline tools and indicates that this is a Datalink Out parameter. Bit 20
must also be set.
25 Datalink In This bit is used by offline tools and indicates that this is a Datalink In parameter. Bits 20 and
22 must also be set.
26 Not Writable While IO Active This parameter cannot be written if the I/O data being exchanged between the Host and the
peripheral is valid.

Common Services
Object Specific Services
The table below lists the parameters for the Get_Attributes_Scattered and
Set_Attributes_Scattered object-specific service.
27 Command Parameter This parameter commands the drive to take an action, such as ‘Reset Defaults’ or
‘Autotune’, and then returns to a value of zero. Offline software tools will not allow setting
this parameter to anything other than a value of zero. If an offline file contains a Command
Parameter with a non-zero value, the offline software tool will change the value to zero.
Note that command parameters cannot have values that do not return to zero.
28 Current Value Is Default This bit identifies a parameter that will not change if a ‘Reset Defaults’ is commanded. For
example, if a drive contains a Language parameter that is set to German, setting defaults
will leave the parameter set to German. Likewise, if the parameter is set to French, setting
defaults will leave the parameter set to French.
29 Use Zero Text If the ‘Disallow Zero’ bit is set, this bit must be cleared. If the ‘Disallow Zero’ bit is cleared,
then:
0 = Use Disabled Text parameter class attribute.
1 = Use Zero Text parameter instance attribute.

20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Glossary
A Adapter
Devices such as drives, controllers, and computers usually require a
network communication adapter to provide a communication interface
between them and a network such as ControlNet. An adapter reads data on
the network and transmits it to the connected device. It also reads data in the
device and transmits it to the network.
The 20-COMM-C (coax) or 20-COMM-Q (fiber) ControlNet adapter
connects PowerFlex 7-Class drives to a ControlNet network. Adapters are
sometimes also called ‘cards’, ‘embedded communication options’,
‘gateways’, ‘modules’, or ‘peripherals’.
B Bridge
A network device that can route messages from one network to another. A
bridge also refers to a communication module in a ControlLogix controller
that connects the controller to a network. See also Scanner.
Bus Off
A bus off condition occurs when an abnormal rate of errors is detected on
the Control Area Network (CAN) bus in a device. The bus-off device cannot
receive or transmit messages on the network. This condition is often caused
by corruption of the network data signals due to noise or data rate
mismatch.
C CAN (Controller Area Network)
CAN is a serial bus protocol on which DPI is based.
CIP (Common Industrial Protocol)
CIP is the transport and application layer protocol used for messaging over
EtherNet/IP, ControlNet, and DeviceNet networks. The protocol is used for
implicit messaging (real-time I/O) and explicit messaging (configuration,
data collection, and diagnostics).
Connected Components Workbench Software
The recommended tool for monitoring and configuring Allen-Bradley
products and network communication adapters. It can be used on computers
running various Microsoft operating systems. You can obtain a free copy of
Connect Components Workbench software at http://www.ab.com/support/
abdrives/webupdate/software.html.
ControlFLASH
A free software tool used to electronically update firmware of
Allen-Bradley products and network communication adapters.
ControlFLASH software is downloaded automatically when the firmware
revision file for the product being updated is downloaded from the
Allen-Bradley updates website to your computer.
G-2 Glossary
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Controller
A controller, also called programmable logic controller, is a solid-state
control system that has a user-programmable memory for storage of
instructions to implement specific functions such as I/O control, logic,
timing, counting, report generation, communication, arithmetic, and data
file manipulation. A controller consists of a central processor, input/output
interface, and memory. See also Scanner.
ControlNet Network
ControlNet is an open producer/consumer communication network with
features, such as redundant media and deterministic I/O timing, designed
for high-performance or time-critical requirements.
More information about ControlNet and the ControlNet specification is
available online at http://www.controlnet.org
.
D Data Rate
The speed at which data is transferred on the ControlNet network (fixed at 5
Mbps).
Datalinks
A Datalink is a type of pointer used by PowerFlex 7-Class drives to transfer
data to and from the controller. Datalinks allow specified parameters to be
read or written to without using explicit messages. When enabled, each
Datalink consumes either four bytes or eight bytes in both the input and
output image table of the controller. The drive determines the size of
Datalinks.
DPI (Drive Peripheral Interface)
A second generation peripheral communication interface used by various
Allen-Bradley drives and power products, such as PowerFlex 7-Class
drives. It is a functional enhancement to SCANport.
DPI Peripheral
A device that provides an interface between DPI and a network or user.
Peripheral devices are also referred to as ‘adapters’ or ‘modules’. The
20-COMM-C or 20-COMM-Q adapter, 1203-USB or 1203-SSS converter,
and PowerFlex 7-Class HIMs (catalog number 20-HIM-xxx) are examples
of DPI peripherals.
DPI Product
A device that uses the DPI communication interface to communicate with
one or more peripheral devices. For example, a motor drive such as a
PowerFlex 7-Class drive is a DPI product. In this manual, a DPI product is
also referred to as ‘drive’ or ‘host’.

DriveExplorer Software
A tool for monitoring and configuring Allen-Bradley products and network
communication adapters. It can be used on computers running various
Microsoft Windows operating systems. DriveExplorer software, version
3.xx or later, can be used to configure this adapter and PowerFlex drives.
This software tool has been discontinued and is now available as freeware
at http://www.ab.com/support/abdrives/webupdate/software.html
. There are
no plans to provide future updates to this tool and the download is being
provided ‘as-is’ for users that lost their DriveExplorer CD, or need to
configure legacy products not supported by Connected Components
Workbench software.
DriveTools SP Software
A software suite designed for running on various Microsoft Windows
operating systems. This software suite provides a family of tools, including
DriveExecutive software (version 3.01 or later), that you can use to
program, monitor, control, troubleshoot, and maintain Allen-Bradley
products. DriveTools SP software can be used with PowerFlex 7-Class and
PowerFlex 4-Class drives, and legacy drives that implement the SCANport
communication interface. Information about DriveTools SP software can be
accessed at http://www.ab.com/drives/drivetools
.
E EDS (Electronic Data Sheet) Files
Simple text files that are used by network configuration tools such as
RSNetWorx for ControlNet software to describe products so that you can
easily commission them on a network. EDS files describe a product device
type and revision. EDS files for many Allen-Bradley products can be found
at http://www.ab.com/networks/eds
.
Explicit Messaging
Explicit Messages are used to transfer data that does not require continuous
updates. They are typically used to configure, monitor, and diagnose
devices over the network.
F Fault Action
A fault action determines how the adapter and connected drive act when a
communication fault (for example, a disconnected cable) occurs or when
the controller is switched out of run mode. The former uses a
communication fault action, and the latter uses an idle fault action.
Fault Configuration
When communication is disrupted (for example, a cable is disconnected),
the adapter and PowerFlex drive can respond with a user-defined fault
configuration. The user sets the data that is sent to the drive using specific
fault configuration parameters in the adapter. When a fault action parameter
is set to use the fault configuration data and a fault occurs, the data from
these parameters is sent as the Logic Command, Reference, and/or
Datalinks.
G-4 Glossary
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
H HIM (Human Interface Module)
A device that can be used to configure and control a drive. PowerFlex
7-Class HIMs (catalog number 20-HIM-xx) can be used to configure
PowerFlex 7-Class drives and their connected peripherals.
Hold Last
When communication is disrupted (for example, a cable is disconnected),
the adapter and PowerFlex drive can respond by holding last. Hold last
results in the drive receiving the last data received via the network
connection before the disruption. If the drive was running and using the
Reference from the adapter, it will continue to run at the same Reference.
Host Parameters (only PowerFlex 750-Series drives)
Host parameters are used to configure peripherals connected to a PowerFlex
750-Series drive. When using a PowerFlex 7-Class HIM (catalog number
20-HIM-A3/-A5/-C3S/-C5S), Host parameters do not appear. When using a
PowerFlex 750-Series HIM (catalog number 20-HIM-A6/-C6S), Host
parameters appear in the HOST PARAM folder. You can also view Host
parameters with any of the following drive configuration tools:
• Connected Components Workbench software—click the tab for the
option module at the bottom of the window, click the Parameters icon in
the tool bar, and open the Host parameters folder.
• DriveExplorer software—find the option module in the treeview and
open its Parameters folder.
• DriveExecutive software—find the option module in the treeview,
expand the module in the tree, and open its Parameters folder.
I Idle Action
An idle action determines how the adapter and connected drive act when the
controller is switched out of run mode.
I/O Data
I/O data, sometimes called ‘implicit messages’ or ‘input/output’, is
time-critical data such as a Logic Command and Reference. The terms
‘input’ and ‘output’ are defined from the controller’s point of view. Output
is produced by the controller and consumed by the adapter. Input is
produced by the adapter and consumed by the controller.
L Logic Command/Logic Status
The Logic Command is used to control the PowerFlex 7-Class drive (for
example, start, stop, and direction). It consists of one 16-bit word of output
to the adapter from the network. The definitions of the bits in this word
depend on the drive, and are shown in Appendix
D.
Glossary G-5
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
The Logic Status is used to monitor the PowerFlex 7-Class drive (for
example, operating state and motor direction). It consists of one 16-bit word
of input from the adapter to the network. The definitions of the bits in this
word depend on the drive, and are shown in Appendix
D.
M Master-Slave Hierarchy
An adapter configured for a master-slave hierarchy exchanges data with the
master device. Usually, a network has one scanner which is the master
device, and all other devices (for example, drives connected to ControlNet
adapters) are slave devices.
On a network with multiple scanners (called a multimaster hierarchy), each
slave device must have a scanner specified as a master.
N Node Address
A unique address that identifies each node on a ControlNet network. The
valid range of ControlNet addresses is 1…99. The ControlNet adapter uses
two rotary switches to set the ControlNet address or, when the switches are
set to ‘00’, uses a parameter to set the node address. The adapter reads the
values of the switches only at power-up.
NVS (Nonvolatile Storage)
NVS is the permanent memory of a device. Devices such as the adapter and
drive store parameters and other information in NVS so that they are not lost
when the device loses power. NVS is sometimes called ‘EEPROM’.
P PCCC (Programmable Controller Communications Command)
PCCC is the protocol used by some controllers to communicate with
devices on a network. Some software products (for example, DriveExplorer
and DriveExecutive software) also use PCCC to communicate.
Ping
A message that is sent by a DPI product to its peripheral devices. They use
the ping to gather data about the product, including whether it can receive
messages and whether they can log in for control.
PowerFlex 7-Class (Architecture Class) Drives
The Allen-Bradley PowerFlex 7-Class family of drives supports DPI and, at
the time of publication, includes the PowerFlex 70, PowerFlex 700,
PowerFlex 700H, PowerFlex 700S, PowerFlex 700L, and PowerFlex 7000
drives.
PowerFlex 750-Series (Architecture Class) Drives
The Allen-Bradley PowerFlex 750-Series of drives supports DPI and, at the
time of publication, includes the PowerFlex 753 and PowerFlex 755 drives.
G-6 Glossary
20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Producer/Consumer Network
On producer/consumer networks, packets are identified by content rather
than an explicit destination. If a node needs the packet, it will accept the
identifier and consume the packet. The source, therefore, sends a packet
once and all the nodes consume the same packet if they need it. Data is
produced once, regardless of the number of consumers. Also, better
synchronization than Master-Slave networks is possible because data arrives
at each node at the same time.
R Reference/Feedback
The Reference is used to send a setpoint (for example, speed, frequency, and
torque) to the drive. It consists of one word of output to the adapter from the
network. The size of the word (either a 16-bit word or 32-bit word) is
determined by the drive.
Feedback is used to monitor the speed of the drive. It consists of one word
of input from the adapter to the network. The size of the word (either a
16-bit word or 32-bit word) is determined by the drive.
RSLogix 5/500/5000 Software
RSLogix software is a tool for configuring and monitoring controllers to
communicate with connected devices. It is a 32-bit application that runs on
various Windows operating systems. Information about RSLogix software
can be found at http://www.software.rockwell.com/rslogix
.
RSNetWorx for ControlNet Software
A software tool for configuring and monitoring ControlNet networks and
connected devices. It is a 32-bit application that can be used on computers
running various Windows operating systems. Information about
RSNetWorx for ControlNet software can be found at http://
www.software.rockwell.com/rsnetworx.
S Scanner
A scanner is a separate module (of a multi-module controller) or a built-in
component (of a single-module controller) that provides communication
with adapters connected to a network. See also Controller.
Status Indicators
LEDs that are used to report the status of the adapter, network, and drive.
They are on the adapter and can be viewed on the front cover of the drive
when the drive is powered.
U UDDT (User-Defined Data Type)
A structure data type that you define during the development of an
application (for example, to convert 32-bit REAL parameter data for written
and read values to correctly display them in human readable format).

Update
The process of updating firmware in a device. The adapter and its connected
PowerFlex 7-Class host drive and its peripherals can be updated using
various Allen-Bradley software tools. See Updating the Adapter
Firmware on page 3-8 for more information.
Z Zero Data
When communication is disrupted (for example, a cable is disconnected),
the adapter and drive can respond with zero data. Zero data results in the
drive receiving zero as values for Logic Command, Reference, and Datalink
data. If the drive was running and using the Reference from the adapter, it
will stay running but at zero Reference.
