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 master Modbus communication channel.

The Modbus communication option is available for the MasterPact MTZ circuit breakers with the MicroLogic X control unit and the ULP port module.

The MasterPact MTZ circuit breakers can be connected:

• to an RS-485 serial line network with Modbus protocol using the IFM Modbus-SL interface for one circuit breaker with part number LV434000.

• 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, IO application module, and so on) and the enabled functions.

Convention

The electrical phases described as phase 1, phase 2, phase 3 cover both IEC standard and UL standard, with the following equivalence:
