Width	36 mm (1 slot)
Depth	86 mm
Mounting	M340 backplane
Slot Requirement	1 (single-width)

This processor module weighs only 0.32 kg for lightweight rack installation. The unit occupies a single slot in an M340 rack. Its height reaches 104 mm with the front cover closed. You can insert the Schneider BMXP342030 next to any M340 I/O modules.

Communication Interfaces

A USB mini-B port provides local programming access to the CPU. One Ethernet port supports Modbus TCP/IP for network communications. The front panel includes an SD card slot for data logging or program backup. You will also find a serial port for Modbus RS-232 connections. Each interface operates independently for multi-protocol support.

Energy Storage and Data Retention

The Schneider BMXP342030 uses a lithium battery for retentive data backup. This battery maintains RAM contents for up to 10 months without external power. An internal supercapacitor provides 72 hours of real-time clock backup. The module also includes 256 KB of non-volatile flash for program storage. You do not lose application code when replacing the battery.

Internal Components and Indicators

A 32-bit RISC processor runs all automation tasks efficiently. The front panel features 7 status LEDs for power, run, and I/O. You will find 16 diagnostic LEDs for communication port activity. The Schneider BMXP342030 contains approximately 210 surface-mount components. A removable SD card slot accepts standard industrial-grade cards up to 2 GB.

System Integration and Use

Transitioning to this CPU simplifies your M340 system architecture. You can program the module using EcoStruxure Control Expert software. The processor supports up to 16 distributed I/O racks over the backplane. Use the Schneider BMXP342030 for pump stations, conveyor systems, or HVAC control. For best results, update the firmware to the latest version before deployment.
