If the AI880A are used in Safety applications there are restrictions on how to
access data and the HART parameter are recommended to be set to Read only.
Device specific HART commands are not predefined and can be implemented as
both read or write commands. If device specific commands are to be used the
parameter has to be set to Full mode.
Note: If the HART routing functionality of AI880A is not restricted by the
modules configuration settings (Read only or Disabled), the operation procedures
must include restrictions for use of this function.
If a write command is sent when the AI880A is in Read only mode the module
will return an error which is reported back to the AI880 DTM. The AI880 DTM
will display an error message “No connection” in the Fieldbus Builder (FBB)
view stating which command that has failed. The AI880 DTM will also send an
error report back to the HART DTM and it is up to this DTM to decide how to act
on the error.
