text: <s>[INST] Loop Detected Error in EN2TR Module. We have rockwell dcs with L75 controller and EN2TR. In one of the network the EN2TR module went to fault with error code as Loop Detected. Beacon time out and interval went to huge number outside the range. Anyone faced this issue? [/INST] Loop problems in DLR networks might be solved declaring a second Supervisor in the network. With 2 supervisors, one be the active supervisor and the other the backup supervisor (selecting which is the active, can be done with the precedence number, the highest wins).\n </s>
