Schneider BMXP341000 Modicon M340 Processor

Schneider Electric BMXP341000 Modicon M340 PLC Processor Module

The Schneider Electric BMXP341000 is a standard-performance programmable logic controller processor module engineered for the Modicon M340 automation platform. It functions as the central processing unit, executing control programs, managing system I/O, and coordinating field communications across machinery and process automation applications.

Capacity and Processing Architecture

The processor handles up to 512 discrete I/O points and 66 analog channels in a single rack, expanding to 128 analog channels and 20 application-specific channels across a maximum of 2 racks (up to 11 slots total). Its internal memory structure includes 2,048 KB of RAM, providing approximately 1,792 KB for program memory and 128 KB for data storage under Unity Pro and EcoStruxure Control Expert environments.

Integrated Connectivity and Expansion Options

Communication interfaces include an integrated 12 Mbit/s USB port for programming and maintenance, alongside an RJ45 serial port supporting RS-232 and RS-485 signaling at rates from 0.3 to 19.2 kbit/s. The serial link supports Modbus RTU/ASCII (Master/Slave) and Character Mode for up to 32 devices per segment across an address range of 0–248. The rack configuration also accommodates up to 2 Ethernet communication modules and 2 AS-Interface modules.
