Can i get Port link failure status while using Dual Ring Switches (DRS)
You may configure the Port link failure via web page. Go to port configuration and enable "Propagate connection error" for eg. ports 3&4. Then under Diagnostics >>Device status >> enable Monitor for Connection error only. Once this is done, the fault led on the switch gets ON when there is a link failure. Also the corresponding fault contact is generated at the connecting terminal 2 & 6, which can be wired as digital input channel of the PLC to know the status.
