Description of the BSCM Modbus SL/ULP Module

Presentation

The BSCM Modbus SL/ULP module with commercial reference LV434220 is a Breaker Status Control Module that can be used to communicate data via:

• Modbus Serial Line communication network

• ULP communication network

The following data is exchanged:

• OF and SDE circuit breaker states from the BSCM Modbus SL/ULP module

• SD circuit breaker state from SD auxiliary contact for BSCM Modbus SL/ULP module or NSX cord (if present)

• Control instructions for the communicating motor mechanism (if present): opening, closing, and resetting

• Information to assist the operator: storage of the last 10 events

When connected to a MicroLogic 5, 6 or 7 trip unit, the BSCM Modbus SL/ULP module gives access to MicroLogic data.

The BSCM Modbus SL/ULP module can be used in the following modes:

• Modbus SL only mode

• Modbus SL and ULP mode

• ULP only mode

If the BSCM Modbus SL/ULP module is used in Modbus SL only mode or in Modbus SL and ULP mode, the MicroLogic 5 or 6 trip units can be used to:

• display the BSCM Modbus SL/ULP module Modbus parameters.

• set the BSCM Modbus SL/ULP module Modbus parameters.
