Communication
10.1 Communication according to PROFIdrive
After activating the measuring function for several measured values per DP cycle, the time
stamp references are saved for transfer in the indices of r0566[4]. Only the value of the time
stamp can be used to identify as to whether the referenced time stamp is a valid measured
value. For a valid time stamp, the consistency to the time stamp reference must be
guaranteed in each DP cycle.
