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.
