Product Details
Product Overview
The Schneider Electric BMXP342020 functions as the high-performance core processing unit for the Modicon M340 programmable automation platform. This mid-range processor coordinates local and distributed I/O architectures, executing complex machine control, instrumentation tracking, and factory automation algorithms. Featuring built-in Ethernet and serial connectivity, this Transparent Ready CPU directly links plant floor equipment with enterprise-level supervisory control and data acquisition (SCADA) networks. We guarantee this processor module arrives in 100% brand new, original factory-sealed condition.

Engineering Advantages
-
Integrated Class B10 Web Server Deployment: The included BMXRMS008MP memory card unlocks native Class B10 web services directly from the CPU. This feature allows plant operators to inspect hardware configurations, review diagnostic counters, and modify application variables remotely via a standard web browser, bypassing the need for dedicated programming software on the factory floor.
-
Deterministic Multi-Task Application Execution: The processor executes a multi-tier task architecture containing a cyclic master task, a fast periodic task, and up to 64 independent event tasks. With Boolean instructions compiling in 0.12 microseconds, this layout allows system designers to segregate slow-moving thermodynamic process loops from high-speed safety interlocks and packaging triggers.
-
Versatile Co-Processor Expansion Capacity: The CPU backplane architecture supports up to two independent Ethernet communication modules and four AS-Interface modules across four local racks. This flexibility enables engineers to integrate massive plant networks without overloading the primary execution cycle of the central processor.
-
Dual-Protocol Baseband Serial Engineering: The non-isolated RJ45 serial port combines RS232C and RS485 physical layer hardware on a single interface, running both master/slave Modbus RTU/ASCII and asynchronous character modes. The system handles long-distance lines up to 3280.8 feet (1000 m) when using external isolation blocks, permitting hassle-free integration of legacy barcode readers, weighing scales, and motor drives.
FAQs
-
Does this BMXP342020 processor come complete with the memory card?
Yes. We ship this processor 100% brand new in its original factory box, which contains the essential Schneider Electric BMXRMS008MP memory card. This card backs up your complete control application, system constants, and user symbols while enabling the embedded web diagnostic services.
-
Can I program this processor module via a standard USB connection?
Yes. The front panel features a high-speed 12 Mbit/s USB type-B programming interface. You can connect your laptop directly to this port using a standard USB cable to upload software configurations, force data values, and view live application logic within the programming environment.
-
What happens to my running application variables if the system loses input power?
The processor retains active application state data internally. The system automatically mirrors critical program parameters, constants, and network settings onto the supplied BMXRMS008MP flash memory card to prevent data corruption or program loss during unexpected power outages.
-
How do I configure the Ethernet port speed on this module?
The integrated RJ45 Ethernet port features an auto-sensing 10BASE-T/100BASE-TX controller interface. It automatically detects the network link speed and duplex settings of your network switches or SCADA terminals, optimizing communication bandwidth without requiring manual hardware DIP-switch adjustments.
