Schneider BMXP342020 Modicon M340 Ethernet CPU Processor Module
| Place of Origin | Germany |
| Brand Name | Schneider Electric |
| Model Number | BMXP342020 |
Product Overview
The Schneider BMXP342020 is a Modicon M340 performance processor module with embedded Ethernet and Modbus serial communication positioning. It is designed for industrial control systems that require direct Ethernet integration with compatible HMI, SCADA, engineering and automation-network equipment.
The processor installs in a compatible Modicon M340 or X80 rack and serves as the central controller for the local I/O and connected automation system. It executes the machine or process application and manages communication according to the configured EcoStruxure Control Expert project.
The BMXP342020 is commonly selected for M340 systems that require embedded Ethernet but do not require the embedded CANopen-master configuration associated with BMXP3420302.

Compatible System and Applications
The BMXP342020 is suitable for factory automation, process-control skids, packaging lines, conveyors, water-treatment equipment, pumping systems and machinery requiring Ethernet connection to compatible control or supervisory devices.
Typical network devices may include HMI panels, SCADA stations, engineering computers, Ethernet communication modules and compatible industrial controllers.
Ethernet compatibility must be evaluated from the complete project rather than only from the presence of an Ethernet port. Required services, communication objects, addressing and network structure may depend on firmware and application configuration.
Maintenance and Replacement Notes
Confirm that the installed processor is BMXP342020. BMXP3420302 includes additional CANopen positioning, while BMXP342000 does not provide the same embedded Ethernet architecture.
Before replacement, save the Control Expert or Unity Pro application, Ethernet settings, serial parameters, firmware version, memory-card contents and full rack configuration.
After installing the replacement processor, the project may require firmware alignment, application download, network testing and verification of every connected I/O and communication module.
Related Models
Related processor references include BMXP3420302 with Ethernet and CANopen, BMXP3420102 with CANopen positioning, BMXP342000 as a performance base processor and BMXP341000 as an entry-level processor.
Inquiry and Supply Notes
Please provide the complete processor reference, firmware version, rack and power-supply models, full module list, Ethernet addressing, serial communication settings and software-project backup status.
Memory-card requirements, communication services, product condition, functional testing, regional availability and delivery time must be confirmed before quotation.
