were just starting to use hart signals from smart devices back to our deltav 11.3.1 system and AMS. In deltav, for each device we can have 4 x device alarms (COMM_ALM, MAINT_ALM, FAILED_ALM & ADVISE_ALM) but the associated module also have a pv bad alarm or module alarm. My question is, whats the difference between the smart alarms and the standard deltav module bad alarm. Is there a need to alarm on both? any advise would be great.
