Product Overview

The Schneider Electric BMXNOM0200 acts as a high-performance, dual-port serial communication bridge for the Modicon M340 and M580 (X80) automation platforms. This module integrates legacy serial-based hardware, such as power meters, VFDs, and barcode scanners, into modern Ethernet-based control architectures. It manages two distinct serial networks simultaneously, preserving existing field-level investments while enabling advanced data acquisition. We supply this module as 100% Brand New and Original, ensuring your industrial network maintains maximum reliability and factory-certified performance.

Technical Specifications

Engineering Advantages

• Dual-Network Autonomy: The BMXNOM0200 features two independent ports, allowing for the simultaneous operation of an RS-232 point-to-point link and an RS-485 multi-drop network. This configuration eliminates the need for multiple communication cards, saving valuable backplane slots and reducing system costs.

• Broad Protocol Versatility: The module natively executes Modbus RTU, Modbus ASCII, and Character Mode (ASCII) instructions. This flexibility ensures seamless communication with a wide variety of third-party instrumentation, from simple weight scales to complex power quality analyzers.

• High-Speed Data Throughput: With programmable baud rates reaching 115.2 kbit/s, the module facilitates rapid data exchange. This speed ensures that process variables from serial field devices update within the PLC's logic cycle, maintaining real-time control accuracy.

• Streamlined Integration via RJ45: The use of standard RJ45 connectors simplifies field wiring. By utilizing Schneider Electric’s range of Modbus cables and T-junctions, engineers can implement secure, vibration-proof connections without the complexity of traditional D-sub wiring.

• Unified Configuration Environment: The module integrates fully with EcoStruxure Control Expert (formerly Unity Pro). Engineers configure communication parameters through a standard software interface, which accelerates commissioning and simplifies future maintenance or network scaling.

FAQs

Can the BMXNOM0200 function as a Modbus Master and Slave simultaneously?

Yes. Since the two ports operate independently, you can configure one port as a Modbus Master to poll field devices and the other as a Modbus Slave to share data with a supervisory system or another PLC.

Does this module require an external power supply?

No. The BMXNOM0200 draws its required 100 mA current directly from the X80 backplane at 3.3 V DC. This "plug-and-play" power capability simplifies cabinet wiring and reduces the load on your field-side 24VDC supplies.

What is the maximum number of devices I can connect via RS-485?

The RS-485 interface supports a multi-drop topology for up to 32 devices (including the master) over a total cable length of 1200 meters, provided you utilize proper termination resistors at both ends of the segment.

How do I verify the condition of this module?

We supply the BMXNOM0200 strictly as 100% Brand New and Original. Each module arrives in original Schneider Electric factory packaging with a verified serial number and carries a 12-month warranty, protecting you against the risks of used or surplus inventory.
