Schneider BMXP342010 M340 Performance CPU Module
The BMXP342010 is a performance CPU module from Schneider Electric's Modicon M340 series. It runs an ARM9 processor at 180 MHz with 3584 KB program memory and a built-in CANopen master port.
Product Introduction
The BMXP342020 serves as the central processing unit for Modicon M340 programmable automation controllers. This performance-level CPU module delivers fast scan times and generous memory capacity for medium to large automation projects. Engineers select this processor when they need reliable control across multiple racks with mixed discrete and analog I/O.
Furthermore, the module integrates both Ethernet TCP/IP and Modbus serial communication ports. This dual connectivity simplifies network architecture and reduces additional hardware costs. The built-in web server provides remote diagnostic capabilities without extra software.
Technical Specifications
The BMXP342020 processor runs on an ARM9 core clocked at 180 MHz. Its program memory reaches 3584 KB, which accommodates application code, symbols, and comments. Data memory is 256 KB for variables and constants. The internal RAM totals 4096 KB.
Scan performance is impressive. Boolean instruction execution takes just 0.12 microseconds. The processor handles 8.1 Kinst/ms for pure boolean logic and 6.4 Kinst/ms for mixed instructions.
For I/O capacity, this CPU supports up to 1024 discrete I/O points. Analog capacity reaches 256 points. A single rack configuration handles 704 discrete and 66 analog points. The module manages one local rack and three expansion racks. Therefore, you can build a system with four racks total.

| Program Memory | 3584 KB |
| Data Memory | 256 KB |
| Internal RAM | 4096 KB |
| Max Discrete I/O | 1024 points |
| Max Analog I/O | 256 points |
| Rack Support | 1 local + 3 expansion |
Communication and Networking
The BMXP342020 includes three built-in communication ports. First, an Ethernet RJ45 port supports 10/100 Mbps connections. This port handles Modbus TCP/IP and HTTP/HTTPS protocols. Second, a Modbus serial RJ45 port operates in RS232 or RS485 mode. Third, a USB Mini-B port serves programming tasks.
The embedded web server operates at Class B10. It enables custom HMI pages and remote monitoring. Additionally, the processor supports optional X80 communication modules for extended network options.
Mechanical and Environmental Parameters
The module measures 100 mm in height, 28 mm in width, and 93 mm in depth. It weighs 0.205 kg. Mounting occurs directly on the X80 backplane.
Operating temperature ranges from 0°C to +60°C. Storage temperature extends from -25°C to +70°C. Relative humidity tolerance is 5% to 95% without condensation. The protection rating is IP20, which suits cabinet installations.
Power consumption is modest at 2.4 W. The module draws 100 mA at 24 V DC through the backplane.
Installation Guide
Installing the BMXP342020 requires proper X80 rack preparation. First, verify that the rack slot is free and the backplane connector is clean. Next, align the module with the rack guides and slide it firmly into position. Then, tighten the safety screw on the front panel to lock the module in place.
For wiring, connect the Ethernet cable to the RJ45 port for network access. Connect the Modbus serial cable to the second RJ45 port if serial communication is needed. The USB port accepts a standard Mini-B cable for programming with EcoStruxure Machine Expert or Unity Pro software.
After power-up, check the eight LED indicators on the front panel. These LEDs show module status, communication activity, and fault conditions. If any red LED remains lit, consult the diagnostic documentation.
