I have recently faced a problem for our PLC that is controlling a Electro-compressor.
Our PLC has communication wit site via two paths, one is via "Fiberoptics Module Profibus"(OZD Profi 12M) and the other is via ET200 S(IM151: 6ES7 151 -1AA02-0ab0). The problem is the IM151 communication failure with PLC, On IM 151 the "SF" led is lit and the "BF" led is blinking, on CPU the "BUS2" is also blinking.
I reloaded the configuration file into PLC, replaced the IM151 with a healthy one, even changed the interconnection cable but the problem was not fixed.
I would greatly appreciate if someone can advise me on resolving the matter.

Vahid
