FAQ

Q: What is the difference between BMXP3420102 and BMXP342030?
A: BMXP3420102 has Modbus serial + CANopen. BMXP342030 has Ethernet + CANopen + USB.

Q: What is the difference between BMXP3420102 and BMXP342000?
A: BMXP3420102 adds CANopen to the Modbus serial interface. BMXP342000 adds Ethernet instead of CANopen.

Q: Can I add Ethernet to BMXP3420102 later?
A: Yes. You can install a separate Ethernet communication module such as BMXNOE0100 or BMXNOC0401 in an adjacent rack slot.
