NW-BM85C002 Multiplexer 8 Data Bits Modbus Plus Schneider

NW-BM85C002 Modicon Multiplexer Module

Product Introduction

The Schneider Electric NW-BM85C002 functions as a specialized multiplexer module designed to streamline communication within Modicon automation networks. This unit operates using the Modbus Plus protocol, which enables high-speed data exchange between controllers, drives, and supervisory systems. It provides a configurable serial interface with 8 data bits and 1 stop bit, allowing engineers to fine-tune port parameters for specific device requirements. Additionally, port priority settings can be adjusted to optimize data flow based on application needs. The NW-BM85C002 supports both panel-mounted and rack-mounted installations, delivering versatility for new projects or system retrofits. Its primary role involves network bridging and signal multiplexing, ensuring efficient data routing across complex industrial topologies.

Modbus Plus Communication Protocol

This multiplexer leverages the robust Modbus Plus networking standard, which is widely adopted in Schneider Electric control systems. Modbus Plus supports high-speed peer-to-peer communication, making it ideal for distributed control architectures. The NW-BM85C002 interfaces seamlessly with other Modbus Plus devices, including PLCs, operator terminals, and remote I/O stations. By handling data multiplexing, it reduces network congestion and improves overall system responsiveness. Furthermore, its compatibility with existing Modbus infrastructure simplifies integration into legacy automation environments. Engineers can deploy this module to expand network capacity without overhauling their current communication infrastructure.

• Communication Protocol: Modbus Plus (High-speed peer networking)

• Data Bits: 8 (Standard serial framing)

• Stop Bits: 1 (Configurable interface)

• Port Priority: Adjustable (Optimized data flow)

• Application: Network bridging and signal multiplexing

Port Configuration and Priority Settings

Serial communication reliability depends on correct parameter configuration, and the NW-BM85C002 addresses this requirement effectively. Its port supports 8 data bits with 1 stop bit, which matches the default settings of most Modbus-compatible devices. Moreover, the port priority feature allows system integrators to assign preference levels to different communication channels. This ensures that critical messages receive bandwidth priority over less time-sensitive data. Consequently, the NW-BM85C002 enhances deterministic communication in mixed-traffic environments. These configurable options make it suitable for applications ranging from simple data logging to complex coordinated motion control.

• Data Framing: 8 data bits, 1 stop bit

• Priority Settings: User-configurable per port

• Interface Type: Serial (Modbus Plus compliant)
