PROFIBUS / 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
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.
Power section DP-V1 can only be used if it is supported by the master and the slaves.
