7.3 Troubleshooting

Troubleshooting of the system is done by examining the LEDs on the front panel of the PLC

and the LEDs on the front of the module. The following can help with troubleshooting.

LINK-LED

 Check the LINK LED status to see if a connection to the Ethernet is established. See

section Ethernet Status (page 86).

Cable

 Check the pin assignment of each connector on the PROFIBUS cable.

 Check if the bus termination resistors are switched on at each end of the cable, and

switched off at all other connectors in between.
