9.1 Via Profibus−DP
PROFIBUS is an integrated, open, digital communication system with a wide application
range mainly in manufacturing and process automation. PROFIBUS is suitable for fast,
time−critical and complex communication tasks.
PROFIBUS−DP can be used for manufacturing automation. It provides for an easy, fast,
cyclic and deterministic process data exchange between a master and the assigned slaves.
Power section DP−V0 is provided with these basic functions. Power section DP−V1 was
enhanced by an acyclic data exchange between master and slave.
Power section DP−V0
Profibus−DP−V0 (Decentralised Peripherals) provides the basic functions of DP.
Power section DP−V1
The power section DP−V1 contains supplements for DP−V0 with the focus on process
automation: Simultaneously to the cyclic process data transfer, an acyclic data link to the
slaves is built up in order to parameterise the slaves.

Note!
Power section DP−V1 can only be used if it is supported by the master and the
slaves.
