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.
8.7 Configure a Discrete Input
Use a Discrete Input to initiate one or more transmitter actions from a remote input device.
Depending on your purchase order and channel configuration, your transmitter may have 0–2 Discrete
Inputs. Channel C can be configured as Discrete Input 1, and Channel D can be configured as Discrete Input 2.

Action Assignment
Discrete Input Action
controls the action or actions that the transmitter will perform when the Discrete Input
transitions from OFF to ON.
CAUTION
Before assigning actions to a Discrete Input, check the status of 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,
change the status of the remote input device or wait until an appropriate time to assign actions.
Procedure
