10.2.1. About the Use Case
The purpose of this use case is to explain how to use the Custom Request/Response serial protocol.
Figure 87. 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 communicaon in the Communicator.
My Drive is connected to the serial subnetwork via a custom RS-485 protocol.
The PLC is connected to an PROFIBUS network (high level network).
We use the Custom Request/Response serial protocol and create customized transacon template to map up:
• Status word and actual speed from My Drive to the PROFIBUS network.
• Control word and speed from the PROFIBUS network to My Drive.
