3.3.2 Implicit Communication
If you use implicit communication, the communications processor (CP)
controls the communication. The types of communication in DP, ZP and GP
in which communication is synchronized with the cycle and for which
handling blocks are used to update information are exceptions.
The difference between GP and DP/ZP is as follows:
GP is used for communication only between active stations
DP/ZP is used for communication between an active and a passive
station.
DP data exchange is only controlled by one master (polling).
