Overview
Discrete Output Fault Action
controls the behavior of the discrete output if the transmitter
encounters an internal fault condition.
Note
For some faults only: 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.
implement the fault action until the timeout has elapsed.
CAUTION!
Do not use Discrete Output Fault Action as a fault indicator. If you do, you may not be able to
distinguish a fault condition from a normal operating condition. If you want to use the discrete
output as a fault indicator, see
