Fault indication with a Discrete Output
To indicate faults via a Discrete Output, set Discrete Output Source to Fault. Then, if a fault occurs, the
Discrete Output is always ON and the setting of Discrete Output Fault Action is ignored.

6.4 Configure the Discrete Input

The Discrete Input is used to initiate one or more transmitter actions from a remote input device. Your
transmitter has one Discrete Input.
The Discrete Input parameters include:
• Discrete Input Action
• Discrete Input Polarity
Important
Whenever you change a Discrete Input parameter, verify all other Discrete Input 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.

ProLink III Device Tools → Configuration → I/O → Action Assignment
Field Communicator Configure → Alert Setup → Discrete Events → Assign Discrete Action
Discrete Input Action controls the action or actions that the transmitter will perform when the Discrete Input
transitions from OFF to ON.
Important
Before assigning actions to an enhanced event or Discrete Input, check the status of the event or the remote
input device. If it is ON, all assigned actions will be performed when the new configuration is implemented. If
this is not acceptable, wait until an appropriate time to assign actions to the event or Discrete Input.
Procedure
1. Select an action.
2. Select the Discrete Input that will perform the selected action.
3. Repeat until you have assigned all the actions to be performed by the Discrete Input.
