Hello.

Few month ago I posted here but not get final answer on this, so I tired one more time.

System running on PLC s7-300 with several profibus ET200 slaves. One of them time to time lost connection with master and goes in error. With it's LED indication I can not determine what is issue, but in diagnostic written: module different form expected. Module with same number as in HW configuration.

 I replaced the module with new one and it worked since than but now same problem appaired again.

Any recommendation, support or advice much appreciated.

See attached video for ET200 LED blinking.
