Serial Link Module Schneider BMXNOM0200

Product Description

The BMXNOM0200 is a dual-port serial communication interface designed for the Modicon M340 Programmable Automation Controller (PAC) platform. It provides reliable connectivity between the PLC and serial-based peripheral devices, supporting Modbus and Character Mode (ASCII) communication.

This module plays a key role in integrating legacy equipment, variable speed drives, HMIs, meters, and third-party instrumentation into a modern control architecture while preserving existing serial networks.

Technical Specifications

Application Scenarios

The BMXNOM0200 is widely used in industrial and infrastructure systems where serial communication remains essential. Typical applications include:

• RS-485 communication with power meters and energy analyzers

• Integration of legacy barcode scanners or serial printers in logistics systems

• Control and monitoring of Modbus RTU–based VFDs

• RTU and telemetry integration in water and wastewater treatment facilities

FAQ

Does the BMXNOM0200 support isolated communication?
No. Both serial ports are non-isolated. For applications requiring electrical isolation, external optical or galvanic isolators should be used.

Can both ports be used simultaneously?
Yes. The two ports operate independently and may be configured with different protocols, baud rates, and roles.

Is this module compatible with the Modicon M580 series?
Yes. As part of the Common I/O range, the BMXNOM0200 can be used in M580 local or remote Ethernet racks (X80 platform).
