Schneider BMXP3420102 Modicon M340 CPU Processor Module with CANopen Master
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | BMXP3420102 |
Product Overview
The Schneider BMXP3420102 is a Modicon M340 performance processor module designed for automation systems requiring embedded CANopen-master and Modbus serial communication positioning.
The processor installs in a compatible Modicon M340 or X80 rack and manages the control application, local I/O system and supported CANopen network devices. It is particularly relevant for machines using CANopen-connected variable speed drives, servo drives, distributed I/O or other compatible field devices.
The BMXP3420102 must not be confused with the BMXP3420302. Both references include CANopen positioning, but BMXP3420302 additionally includes embedded Ethernet positioning.

Compatible System and Applications
The BMXP3420102 is suitable for packaging machinery, conveyors, material-handling equipment, assembly systems and industrial machines using CANopen-connected drives or distributed devices.
The CANopen network configuration is part of the machine-control project. Replacement requires the original node list, baud rate, device profiles, termination arrangement and controller application.
Where Ethernet communication is required, verify whether the system uses a separate Ethernet communication module or whether a different CPU reference is required.
Maintenance and Replacement Notes
Verify the complete BMXP3420102 reference before ordering. BMXP3420302 provides Ethernet and CANopen positioning, while BMXP342020 is primarily the embedded-Ethernet processor variant.
Before replacement, back up the Control Expert or Unity Pro application, CPU firmware, CANopen network configuration, serial parameters, memory-card data and full rack-module list.
Do not assume that a replacement CPU with CANopen will operate correctly without restoring the original application and validating every network node.
