Modbus Cradle Communication Module (CCM)

The optional Modbus cradle communication module (CCM) is installed adjacent to the circuit breaker

cradle and is the gateway between the Modbus network and the Modbus BCM. The Modbus CCM

provides circuit breaker cradle status including connected position (CE), disconnected position (CD) and

test position (CT). The CCM monitors the communication parameters of the Modbus BCM and trip unit

when it detects a circuit breaker being racked from the cradle. When the circuit breaker is reinstalled or a

spare circuit breaker is installed and racked into the cradle, the CCM automatically downloads the

address, baud rate, and parity into the BCM. This capability allows a circuit breaker to be replaced

without the need to manually configure the communication parameters in the Modbus BCM.

The CCM maintains an event log of the date and time of the last circuit breaker transition. In order to

aid system communication troubleshooting, the CCM has visual indication of the module’s operating

status by means of two LEDs.
