4.3.8 ProfiBus-DP interface
With the Profibus-DP a centrally directed data exchange between master
and slaves is possible. The master (e.g. automation system PLC) carries out
the cyclic exchange of process data with the slaves (drives, I/O) one after the
other, in a fixed sequence.
Communication protocols and syntax comply with the ProfiBus-DP standard
to IEC 61158.
The interface can be configured by front keys.
