Product Overview
The Schneider BMXP342000 processor module is a key component of the Modicon M340 automation platform, designed to serve as the control brain in moderate-complexity industrial systems. It supports up to 1024 discrete I/O points and 256 analog I/O channels, making it an excellent choice for upgrading from older Modicon platforms or for new installations requiring reliable, scalable processing. With built-in Modbus serial communication and a generous 4 MB internal RAM (including 256 kB data and 3584 kB program/constants/symbols), the BMXP342000 handles demanding control tasks efficiently.

Industry Applications
The BMXP342000 excels in applications such as water treatment, material handling, and packaging lines where moderate I/O counts and deterministic control are required. For example, in a conveyor sorting system, its 1024 discrete I/O capacity handles numerous sensors and actuators, while the Modbus serial link integrates easily with variable-frequency drives and HMIs. In a wastewater treatment upgrade project, replacing an older PLC with the Schneider BMXP342000 reduces downtime while offering robust analog I/O for pH and flow monitoring.
Compatibility & Integration
This processor module fits into a single-rack or multi-rack Modicon M340 backplane with 11 slots. It supports up to 2 Ethernet communication modules and 4 AS-Interface modules for expanded networking. The BMXP342000 uses the Modbus RTU/ASCII protocol over RS232C or RS485, enabling communication with a wide range of legacy and modern devices. It also includes a USB port for local programming via EcoStruxure Control Expert.
Selection Guide & Purchasing Advice
When upgrading or replacing a control system, ensure the existing rack and power supply are compatible with the Modicon M340 platform. The BMXP342000 requires a supplied memory card (BMXRMS008MP) for reliable program backup.
