Output simulation State of relay 1 State of relay 2 Expected result on the
terminals of the I/O module
Simulating active Closed Closed Closed
Simulating inactive Open Open Open
Fault 1 Closed Open Open
Fault 2 Open Closed Open
The Fault 1 and Fault 2 options can be used to check the correct switching behavior
of the two relays.
