None (default) Discrete output is controlled by its assignment
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.
6.5 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.
Your transmitter supports two event models:
Basic event model
Enhanced event model
Integrate the meter with the control system
