FAQ

Q: How do I decode the Schneider M340 processor suffix?
A: The suffix digits indicate integrated communication: BMXP342000 = Modbus serial + Ethernet; BMXP3420102 = Modbus serial + CANopen; BMXP342030 = Ethernet + CANopen + USB. The trailing H indicates severe environment coating.

Q: What is the difference between BMXP341000 and BMXP342000?
A: BMXP341000 is a Level 1 standard CPU with 512 discrete / 128 analog I/O and 2 MB RAM. BMXP342000 is a Level 2 performance CPU with 1,024 discrete / 256 analog I/O and 4 MB RAM.

Q: What software is used to program this processor?
A: EcoStruxure Control Expert (formerly Unity Pro) is the programming environment for all BMXP34 series processors.

Q: Is the SD memory card included?
A: Yes. The processor ships with an 8 MB SD memory card (BMXRMS008MP).

Installation Guide

1. Install the processor in the first slot of the X80 rack (slot 00)
2. Connect 24 V DC power to the rack power supply
3. Attach Ethernet cable to the RJ45 port for network communication
4. Connect programming cable to the USB Mini-B port
5. Insert the SD memory card into the front slot
6. Configure processor and I/O using EcoStruxure Control Expert
7. Verify RUN and ERR LEDs indicate proper startup status

Selection Tips

• Select BMXP342000 for performance applications requiring integrated Ethernet and Modbus serial
• For Modbus + CANopen, choose BMXP3420102
• For Ethernet + CANopen + USB, choose BMXP342030
• For standard Level 1 applications, BMXP341000 provides cost-effective control
• For harsh environments, select the H-suffix variant (e.g., BMXP342000H)
