Communication and process data exchange

The software module's hardware topology includes at least the following system components that communicate with each other:

  • MOVI-C® CONTROLLER with the software module
  • Application inverter

The MOVI-C® CONTROLLER with the software module uses the EtherCAT®-based system bus to communicate with the application inverters. To ensure unique addressing of the messages and thus of the motion tasks for each individual drive, each application inverter requires a different address on the system bus.

In addition, there may be an optional Programmable Logic Controller (PLC) that is on a higher topological level than the MOVI-C® CONTROLLER. The MOVI-C® CONTROLLER communicates with the PLC via the fieldbus. Process data is exchanged for this purpose. Both systems must know how to interpret the data.
