Features of a Master class 1 connection
- Cyclical data exchange (DP V0)
- Acyclical read/write on parameters
- Extended diagnosis
The acyclical connection is fixed, and cannot be
changed during operation.
FeaturesofaMasterclass2connection:

- Acyclical read/write on parameters
The acyclical connection can be established
(Initiate) or removed (Abort) dynamically even
whenamasterclass1isactiveonthenetwork.
The DP V1 acyclical connection can be used for
general parameter access as an alternative to the
PCV parameter channel.
PROFIBUS DP V1
The PROFIBUS DP extension DP V1 permits acyclical as well as cyclical data commun ication. This feature can
be used by a DP master class 1 (e.g. PLC), as well as a DP master class 2 (e.g. PC tool).
