I am running 1756-L63 ControlLogix PLC with 1756-CNB/E. One of the modules in this network is 1788-CN2DN ControlNet to DeviceNet converter. I am trying to commission this unit and have encountered a problem. Module Status flashes RED and Linking Activity Status is OFF. Iran RSNetWorkx for COntrolNet and the itpicks up the module with "Missing" Status. Read manuals and tried everything and I am not able to get the Linking Activity Status to flash green and Module Status to turn off. Any suggestions ?
