It’s possible to do it via Modbus TCP protocol.

For the CMC-EIP01 card this is supported starting with firmware V1.08 (date code: W1852).

For the CMC-EIP02 card this is supported on all firmware versions.

The drive firmware needs to be at least:

  • CP2000 – V2.06 or higher.
  • CFP2000 – V1.06 or higher.
  • C2000 – V2.06 or higher.
  • C2000 Plus – V3.06 or higher.

For the CMM-EIP01 and CMM-EIP02 cards this is supported starting with firmware V1.04 (date code: W1850)
For the CMM-EIP03 card this is supported on all firmware versions

The drive firmware needs to be at least:
