Loading...What to do if all signals for a station are faulty in Pepperl+Fuchs I/O Systems?
If all signals for a station are faulty in your Pepperl+Fuchs I/O Systems, start by checking that the power supply is working properly. Next, inspect the bus connection for any issues. Finally, use a bus monitor to check the bus communication itself.
