Discrete Output Fault Action
controls the behavior of the discrete output if the transmitter encounters an
internal fault condition.
Note
If
Last Measured Value Timeout
is set to a non-zero value, the transmitter will not implement the fault action
until the timeout has elapsed.
Do not use
Discrete Output Fault Action
as a fault indicator. Because the discrete output
is always ON or OFF, you may not be able to distinguish its fault action from its normal
operating state.
Procedure
Set
Discrete Output Fault Action
as desired.
The default setting is
None
