Use of imperatives in HART Specifications
The key words (imperatives) "must", "required", "shall", "should", "recommended", "may", and "optional" when
used in this document are to be interpreted as follows:
Must
Must, Shall, or Required denotes an absolute mandatory requirement. For example, "All HART Field Devices
must implement all Universal Commands"
Should
Should or Recommended indicates a requirement that, given good cause/reason, can be ignored. However,
the consequences of ignoring the requirement must be fully understood and well justified before doing so.
May
May or Optional identifies a requirement that is completely optional and can be supported at the discretion of
the implementation. May can be used to identify optional Host Application or Master functionality and, when
this is the case, does not imply the function is optional in Field Devices.
Intellectual Property Rights
The FieldComm Group does not knowingly use or incorporate any information or data into the HART
Specifications which the FieldComm Group does not own or have lawful rights to use. Should the FieldComm
Group receive any notification regarding the existence of any conflicting Private IPR, the FieldComm Group will
review the disclosure and either (a) determine there is no conflict; (b) resolve the conflict with the IPR owner; or
(c) modify this specification to remove the conflicting requirement. In no case does the FieldComm Group
encourage implementers to infringe on any individual's or organization's IPR.
