AC Motor Drive - Custom Request/Response Use Case


In this use case we use the Communicator to enable data exchange between an AC motor, of the type My Drive, and a PLC.

The use case describes how to map the communication in the Communicator.

My Drive is connected to the serial subnetwork via a custom RS-485 protocol.

The PLC is connected to an EtherNet/IP network (high level network).

We use the Custom Request/Response serial protocol and create customized transaction template to map up:

  • Status word and actual speed from My Drive to the EtherNet/IP network.

  • Control word and speed from the EtherNet/IP network to My Drive.
