The DiscreteDevice object provides sophisticated alarming capabilities, including:
-
Command timeout alarm, which indicates that the PV state did not change to match the Cmd state within a configurable timeout period.
-
Uncommanded change alarm, which indicates that the PV state changed from the expected Cmd state to some other state and the quality of PV is GOOD or UNCERTAIN (not BAD).
-
Individual alarms for each of Active1, Active2, and Fault state conditions.
-
Duration alarms for each of Active1 and Active2 states, indicating the discrete device has been in the state for too long of a time period.
