10.1 Via Profibus−DP
Profibus−DP−V0 (Decentralised Peripherals) provides the basic functions of DP.
This includes the cyclic data exchange as well as diagnostic functions.
l Diagnostic functions for fast error localisation:
– Code−related diagnostics
– Module status
– Channel−related diagnostics
Power section DP−V1 includes enhanced functions of DP−V0 with regard to
process automation:
l Alarms for enhanced diagnostics
– Status alarm, update alarm, manufacturer−specific alarm
l Simultaneously to the cyclic process data transfer, an acyclic data circuit to
the slaves is created in order to
– parameterise the slaves,
– evaluate alarms.

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