3.1.4. DP user data
With PROFIBUS, process data are exchanged cyclically between
master and controller in the user-data phase. In addition to the
process data you can activate a DP parameter setting channel
which will use the first 8 byte of the user data. The data structure is
the same for input and output data, see following tables.
