Selection Guide
Use the following criteria to determine whether BMXP341000 is the right processor for your application, or to select an appropriate upgrade:
- Application size ≤ 512 KB program + ≤ 1,024 I/O points → BMXP341000 is sufficient
- Need > 512 KB memory or > 1,024 I/O → Upgrade to BMXP342000 or BMXP3420302
- CANopen fieldbus required → Select BMXP342010
- Profibus DP master required → Select BMXP342020
- Harsh/humid environment → Specify BMXP341000H (conformal coated)
- Dual Ethernet redundancy required → Select BMXP3420302 (2 × Ethernet ports)
- Replacing a failed unit like-for-like → BMXP341000 is the direct replacement; confirm firmware version compatibility with existing rack

Replacement & Compatibility FAQ
Q: Can BMXP342000 directly replace BMXP341000 without hardware changes?
A: Yes, the BMXP342000 is physically compatible with all M340 racks. A firmware update and program re-download via Unity Pro is required. Memory addressing is backward compatible.
Q: Is BMXP341000 compatible with Modbus RTU SCADA systems?
A: Yes. The integrated RS-485 serial port supports Modbus RTU and ASCII protocols natively, enabling direct connection to legacy SCADA systems without additional communication modules.
Q: What is the difference between BMXP341000 and BMXP341000H?
A: The BMXP341000H features conformal coating on the PCB for enhanced resistance to humidity, condensation, and corrosive atmospheres. Functionally identical; select H-variant for harsh environments.
Q: Can I use EcoStruxure Control Expert instead of Unity Pro?
