Modbus Communication

The Modbus communication option enables Schneider Electric low voltage circuit breakers to be connected to a supervisor or to any other device with a master Modbus communication channel.

The circuit breakers can be connected to an RS-485 serial line network with Modbus protocol or an Ethernet network with Modbus TCP/IP protocol using dedicated interfaces like:

• the IFM Modbus-SL interface for one circuit breaker to connect the circuit breaker to an RS-485 serial line network or,

• the IFE Ethernet interface for one circuit breaker or the IFE Ethernet switchboard server to connect the circuit breaker to an Ethernet network.

Access to Functions

The Modbus communication option provides access to many functions, including:

• read metering and diagnostic data

• read status conditions and remote operations

• transfer of time-stamped events

• display protection settings

• read the circuit breakers identification and configuration data

• remote control of the circuit breaker

• time-setting and synchronization

This list depends on the composition of the intelligent modular unit (IMU) (type of circuit breaker, of MicroLogic trip unit, and so on) and the enabled functions.
