You can enable open circuit diagnostics on any digital output channel. If the output channel is energized and the current falls below open circuit detection specifications, the User Program will return a fault on DOn.OpenCircuitFault.
You can use open circuit faults in two ways:
You can check the Fail-safe box for DOn.OpenCircuitFault. If an open circuit fault occurs, the module will go into Fail-safe Mode.
You can use DOn.OpenCircuitFault in transition logic on the State Machine Diagram. If an open circuit fault occurs, the User Program will transition to a user-configured state.
