Schneider BMXP341000 M340 CPU Module Level 1

Schneider Electric BMXP341000 Modicon M340 Standard CPU Module

Product Introduction

The BMXP341000 belongs to the Modicon M340 automation platform from Schneider Electric. This Level 1 CPU handles mid-range control tasks for machines and process lines. Moreover, it supports up to 512 discrete points and 128 analog points. As a result, system integrators use it in manufacturing, water treatment, and building automation projects.

Technical Specifications

Processor and Memory

First, the module runs an ARM9 processor with a 110 MHz clock speed. It provides 1792 KB of program memory for applications, symbols, and comments. Besides, it offers 128 KB of data memory for data and constants. The total internal RAM reaches 2048 KB, which supports smooth program execution.

Scan Performance

Next, the CPU executes 5.4 Kinst/ms for 100% boolean instructions. It also reaches 4.2 Kinst/ms for mixed instructions. Therefore, it meets the demands of fast logic and interlock routines. Meanwhile, engineers program it with EcoStruxure Machine Expert or Unity Pro.

I/O Capacity and Rack Support

Moreover, the controller supports up to 512 discrete I/O points. It also handles up to 128 analog I/O points. The CPU fits 4, 6, 8, and 12-slot X80 racks. In addition, it accepts one main local rack and one expansion rack.

Communication Features

The CPU includes one Modbus serial port on RJ45 with RS232/RS485. Furthermore, it provides one USB Mini-B port for programming. The serial port supports Modbus RTU, Modbus ASCII, and character mode. Additionally, optional X80 modules add Modbus serial, CANopen, Ethernet/IP, or extra serial links.

Electrical Parameters

Specifically, the module draws 2.2 W of power. It consumes 90 mA of bus current at 24 V DC. The supply voltage is 24 V DC through the backplane.

Mechanical and Environmental Parameters

The CPU measures 100 × 28 × 93 mm (H×W×D). It weighs 0.200 kg, so it fits compact panels. The operating temperature range spans 0°C to +60°C. Meanwhile, storage temperature ranges from -25°C to +70°C. Relative humidity tolerance sits between 5% and 95%, non-condensing. Finally, the protection rating is IP20.

Installation Guide

Mounting Steps

First, confirm that the X80 rack has a free CPU slot. Next, align the module with the rack guides. Then, slide it in until the backplane connector seats fully. After that, tighten the retaining screw.

Wiring and Commissioning

Additionally, connect the Modbus serial cable to the RJ45 port. Confirm that the RS232 or RS485 mode matches the field device. Furthermore, download the application through the USB or serial link. Finally, verify I/O mapping before running the process.

Lifecycle Note

However, this CPU reached End of Sale on 2020-11-01. Therefore, buyers should plan a migration to M580 or the current M340 range. Meanwhile, the BMXP341000 remains available through surplus and refurbished channels.
