Fault indication with the discrete output
To indicate faults via the discrete output, set parameters as follows:
•
Discrete Output Source
= Fault
•
Discrete Output Fault Action
= None
Note
If Discrete Output Source is set to Fault and a fault occurs, the discrete output is always ON. The setting
of Discrete Output Fault Action is ignored.

Configure events
An event occurs when the real-time value of a user-specified process variable moves past a
user-defined setpoint. Events are used to provide notification of process changes or to
perform specific transmitter actions if a process change occurs.
user-defined setpoint. Events are used to provide notification of process changes or to
perform specific transmitter actions if a process change occurs.
Your transmitter supports two event models:
•
Basic event model
•
Enhanced event model
