-
PLC communicates with telegrams of constant
length
-
Fits time-critical requirements
-
Cyclical transmission via PPO types
-

PROFIBUS DP V0
Bus Topology
Multiple master
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.
Features of a Master class 2 connection:
-
Initiate / Abort acyclical connection
-
Acyclical read/write on parameters
The acyclical connection can be established
(Initiate) or removed (Abort) dynamically even
when a master class 1 is active on the network.
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 communication. 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).
