Schneider BMENUA0100 M580 Serial Module

Schneider BMENUA0100 Modicon M580 Serial Module

Product Introduction

The BMENUA0100 provides serial communication capability for the Schneider Electric Modicon M580 platform. Specifically, it bridges modern Ethernet-based controllers with legacy serial devices. This module installs in an X80 rack using a single X-bus slot. As a result, engineers can integrate existing Modbus RTU or ASCII equipment without replacing field devices. Furthermore, the BMENUA0100 supports both RS232 and RS485 physical layers. It suits applications involving weigh scales, barcode readers, analyzers, and older drives. Typical industries include water treatment, food processing, and legacy manufacturing upgrades.

Technical Specifications

Port Configuration and Compatibility

One serial port supports both RS232 and RS485 standards. The port handles point-to-point and multidrop network topologies. Wiring selection depends on cable length and noise conditions. RS232 suits short-distance connections up to 15 meters. Meanwhile, RS485 supports longer runs up to 1200 meters in noisy environments. The module fits any X80 rack with an available X-bus slot.

Communication Protocols

The module supports Modbus RTU and Modbus ASCII protocols. These protocols enable communication with Modbus-compatible devices such as sensors, meters, and PLCs. Additionally, character mode allows raw data transmission for custom protocols. This flexibility helps integrate non-standard serial equipment. Data rates and framing parameters are configurable through the programming software.

Electrical Characteristics

Power comes from the backplane supply. The module accepts 3.3 V DC and 24 V DC via the backplane. Bus current draw reaches 300 mA at 5 V DC. Since the module draws power internally, no separate power wiring is required. This design simplifies cabinet layout and reduces installation cost.

Mechanical and Environmental Parameters

The module measures 100 × 28 × 93 mm (H × W × D) and weighs approximately 0.15 kg. It occupies 1 slot on the X-bus backplane. The IP degree of protection is IP20, suitable for cabinet installation. Operating temperature ranges from 0°C to +60°C. Storage temperature spans -25°C to +70°C. Relative humidity tolerates 5% to 95% without condensation.

Installation Guide

Step 1: Prepare the Rack

First, disconnect all power sources before starting installation. Verify that the X80 rack has an available X-bus slot. Remove the protective cover from the target connector.

Step 2: Insert the Module

Next, align the BMENUA0100 with the guide rails on the selected slot. Push the module firmly into the backplane connector until it seats completely.

Step 3: Secure the Module

Once seated, tighten the retaining screw at the top of the module. Confirm that the module sits flush against the rack.

Step 4: Wire and Configure

Finally, connect the serial cable to the RS232 or RS485 terminals. Apply power and configure protocol parameters through the programming software. Verify communication with the connected serial device.
