We are facing the problem of communication failure between seimens drives and ABB DCS. Between drives and DCS on RLM -01 module for communication purpose. We found red blinking i.e error blinking in RLM -o1 module. So we replaced with new one but after one month same problem again came. So again we installed old RLM-01 module. Now also RED blinking is coming but sometimes drives are not tripping. What will be the cause for this problem?
