Integrate the meter with the control system
The discrete output parameters include:
•
Discrete Output Source
•
Discrete Output Polarity
•
Discrete Output Fault Action
•
Discrete Output Power Source
Postrequisites
Important
Whenever you change a discrete output parameter, verify all other discrete output parameters before
returning the flowmeter to service. In some situations, the transmitter automatically loads a set of stored
values, and these values may not be appropriate for your application.
