Cyclic diagnostics

Cyclic process data can be found directly below the PROFINET controller protocol. This data is only exchanged between the PROFINET driver and TwinCAT 3. It provides general information about the status of the device and the configured boxes.

The process data DevState. contains information about the physical communication status of the device, such as the link status or whether the sender resources are still adequate.

The output process data DevCtrl currently has no function.
