Description

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 Modbus client communication channel.

The circuit breakers can be connected to:

An RS-485 serial line network with Modbus protocol using dedicated interfaces such as:
- The BSCM Modbus SL/ULP module and the Modbus SL hub.
- The IFM Modbus SL communication interface for one circuit breaker.
An Ethernet network with Modbus TCP/IP protocol using dedicated interfaces such as:
- The IFE Ethernet communication interface for one circuit breaker.
- The IFE Ethernet switchboard server.

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.
