Schneider BMXP3420302 Modicon M340 Ethernet CANopen CPU Processor Module
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | BMXP3420302 |
Product Overview
The Schneider BMXP3420302 is a high-performance Modicon M340 processor module designed for industrial automation systems requiring embedded Ethernet, CANopen master and Modbus serial communication.
This processor is used as the central CPU within a compatible Modicon M340 and X80 rack architecture. It executes the control application, manages local and distributed I/O, exchanges data with connected automation devices and coordinates supported communication networks.
The combined Ethernet and CANopen architecture makes the BMXP3420302 particularly relevant for machines and process systems using HMI panels, SCADA systems, variable speed drives, servo drives, remote I/O and other compatible CANopen or Ethernet devices.

Compatible System and Applications
The BMXP3420302 is suitable for manufacturing lines, packaging machinery, material-handling equipment, water-treatment systems, process skids, conveyors and automation systems requiring both Ethernet and CANopen communication.
The Ethernet interface may connect compatible HMI, SCADA, engineering stations and industrial network devices. The CANopen master may coordinate compatible drives, remote I/O and other CANopen nodes.
The complete architecture must be reviewed before replacement, including the rack, power supply, I/O modules, communication modules, Ethernet addressing, CANopen node list and serial settings.
Maintenance and Replacement Notes
Verify the complete BMXP3420302 commercial reference. BMXP342020 provides embedded Ethernet but does not have the same CANopen positioning, while BMXP3420102 provides CANopen positioning without the same embedded Ethernet configuration.
Before removing the installed processor, back up the EcoStruxure Control Expert or Unity Pro project, CPU firmware, memory-card data, Ethernet configuration, CANopen topology, serial parameters and complete rack-module list.
A replacement CPU may require firmware alignment, project download, network reconfiguration and a controlled machine restart. Do not assume plug-and-run replacement without the original application backup.
