Product Overview

When your automation system demands reliable and scalable control, the Schneider BMXP3420102CL processor module delivers. Part of the Modicon M340 platform, this module handles up to 1024 discrete I/O in multi-rack configurations and 704 I/O in single-rack setups. It requires a memory card (not supplied) to operate, ensuring your application data stays secure and customizable.

Technical Specifications

The BMXP3420102CL offers robust performance with an internal RAM of 4096 kB, including 256 kB for data and 3584 kB for program constants and symbols. Execution times are efficient: 0.12 µs for Boolean instructions and 1.16 µs for floating points. It supports up to 4 racks and 11 slots, with a current consumption of 90 mA at 24 V DC. The module weighs 0.21 kg and operates in ambient temperatures from 0 to 60 °C.

Industry Applications

This processor module excels in discrete manufacturing, process control, and material handling systems. Its CANopen master interface supports up to 63 devices, making it ideal for coordinated motion control in packaging lines or conveyor systems. The integrated Modbus serial links enable seamless communication with legacy equipment, reducing integration costs.

Installation & Setup

Mount the BMXP3420102CL onto a Modicon M340 rack using the internal power supply via rack. Insert a compatible memory card (sold separately) before powering up. Configure the module using Unity Pro software, setting up CANopen and Modbus parameters as needed. Ensure the ambient temperature stays within 0–60 °C and relative humidity between 10–95% without condensation.

Maintenance & Reliability

The BMXP3420102CL includes diagnostic counters for Modbus and event counters, simplifying troubleshooting. Its IP20 protection suits clean industrial environments. Regularly inspect status LEDs—green for processor running, red for faults—to catch issues early. Following manufacturer guidelines for periodic checks extends service life and minimizes downtime.

Compatibility & Integration

This module integrates with up to 2 Ethernet communication modules and 4 AS-Interface modules. It supports CANopen M20 DS 301 V4.02, DS 303-2, and DS 405 devices via daisy-chaining. Serial links include RS232C and RS485 for Modbus RTU/ASCII and character mode, with baud rates from 0.3 to 19.2 kbit/s. The USB port at 12 Mbit/s facilitates local programming.
