A motor control center communication system (100) configured to interface with a communication network (16). The system includes a plurality of motor control units (MCUs) (18), and a MCU controller (12) configured to transmit and receive data signals via the communication network (16) to and from, the plurality of MCUs (18). Each of the plurality of MCUs (18) includes a magnetic contactor (22) having electrical contacts operable between open and closed positions, and a local control module (30) operatively connected to the associated magnetic contactor (22) and to the MCU controller (12), and configured to monitor a status of the electrical contacts, transmit the monitored status information to the MCU controller (12), and actuate the associated magnetic contactor (22) based on data signals received from the MCU controller (12). |
