RequestID
The RequestID field in the request buffer header can be used by PLC to identify the answer. It is the
responsibility of the PLC program to manage the field RequestID. The best practice is to increment
this field before each new request. The PROFINET firmware will answer to the request with the sa-
me RequestID.
