Description

Modbus Communication

The Modbus communication option enables Schneider Electric low voltage circuit breakers to be connected to a network with a client Modbus communication channel.

The Modbus communication option is available with:

• MasterPacT MTZ circuit breakers with MicroLogic X control unit

• MasterPacT MTZ circuit breakers with MicroLogic Active control unit and BCIM module

• MasterPacT NT/NW, ComPacT NS and PowerPacT P- and R-frame circuit breakers with MicroLogic A/E/P/H trip unit and BCM ULP module

• ComPacT NSX and PowerPacT H-, J-, and L-frame circuit breakers with MicroLogic 5/6/7 trip unit and BSCM module

The circuit breakers can be connected:

• to an RS-485 serial line network with Modbus RTU protocol using the IFM Modbus-SL interface for one circuit breaker

• to an Ethernet network with Modbus TCP/IP protocol using dedicated interfaces like:

  • the IFE Ethernet interface for one circuit breaker.

  • the IFE Ethernet switchboard server.

  • the EIFE embedded Ethernet interface for MasterPacT MTZ drawout circuit breaker.

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 (type of circuit breaker, type of MicroLogic control unit or trip unit, IO application module, and so on) and the enabled functions.
