4.6 Protocol
The AD3000 is presented to the PROFIBUS DP network as a slave, enabled for data exchange functions. Data exchange is implemented according
to the PROFIdrive communication profile.
The protocol used is PROFIBUS DP-DP; with this standard, the message exchanged between master and slave can have five structure types,
identified with the following codes: PPO1, PPO2, PPO3, PPO4 and PPO5.
The above-mentioned codes univocally define , for the messages received and sent from the Drive protocol, both the message size (number of words)
and the position and typology of all the data in the message.
The types of data present in the messages are divided into two categories:
 parameterisation data (PKW);
 process data (PZD).
The drive control is able to manage both PKW parameterisation data and PZD process data.
4.7 Structure of messages sent and received through the PROFIBUS DP network
The following tables report the structure of every message received or sent by the AD3000 control according to the PPO used, the typology and
meaning of every word:
