Turn off the power supply to the node.
Plug in an end module behind the fieldbus coupler.
Turn the power supply on.
Observe the error argument signaled.
Replace the fieldbus coupler.
Identify the faulty I/O module by turning off the power
supply.
Plug the end module into the middle of the node.
Turn the power supply on again.
