Adapter

If you carry out a search in the System Manager for devices, the CCAT interface for the PROFINET interface will automatically be found. CCAT is a Beckhoff-internal software and hardware interface for various bus systems, which in the case of the CX8093 contains PROFINET support.

The adapter Reference must thereby refer to the CCAT.

The Freerun Cycle Time is the time at which the PROFINET is triggered in the Config Mode. This not served from the TwinCAT real-time and is therefore only conditionally real-time-capable, which may lead to PROFINET failures in the case of the master. In such cases you can either increase the Freerun Cycle Time or switch the TwinCAT on the CX to RUN mode.
