The BMXP342030 serves as the central processing unit for Modicon M340 programmable automation controllers. This performance-level CPU combines a CANopen master port with Ethernet TCP/IP communication. Engineers select this module when their machines rely on CANopen devices and also need plant network access.
Furthermore, the integrated CANopen master follows the DS405 profile. This allows direct control of drives, remote I/O, and encoders without extra communication cards. Meanwhile, the Ethernet port handles Modbus TCP/IP traffic and programming tasks.
The BMXP342030 processor runs on an ARM9 core clocked at 180 MHz. Its program memory reaches 3584 KB, which covers application code, symbols, and comments. Data memory is 256 KB for variables and constants. Internal RAM totals 4096 KB.
Scan performance meets demanding control requirements. 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. The module manages one local rack plus three expansion racks. Therefore, a full system can use four racks in total.
The table below summarizes the key parameters:
| Parameter | Specification |
|---|---|
| Processor | ARM9, 180 MHz |
| 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 |
| Application Channels | 36 |
The BMXP342030 includes three built-in communication ports. First, a CANopen RJ45 port acts as a master on the DS405 profile. Second, an Ethernet RJ45 port supports 10/100 Mbps connections for Modbus TCP/IP. Third, a USB Mini-B port serves programming tasks.
Additionally, optional X80 communication modules expand connectivity further. Supported options include the BMXNOM0200 for Modbus serial and the BMENOC03xx for Ethernet/IP. These modules slot into the rack alongside the CPU.
The module measures 100 mm in height, 28 mm in width, and 93 mm in depth. It weighs 0.200 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 2.9 W. The module draws 120 mA at 24 V DC through the backplane. Supply voltage arrives via the rack, so no separate power wiring is required.
Installing the BMXP342030 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 CANopen cable to its RJ45 port for device networking. Connect the Ethernet cable to the second RJ45 port for plant network access. The USB port accepts a standard Mini-B cable for programming with EcoStruxure Machine Expert or Unity Pro software.
After power-up, check the LED indicators on the front panel. These LEDs show module status, CANopen activity, Ethernet link status, and fault conditions. If any red LED remains lit, consult the diagnostic documentation.
