Figure 6-8
Every telegram for cyclic data exchange has the following basic structure:
● Header and trailer form the protocol frame.
● User data is located within the frame:
– PKW: The control can read or change every parameter in the inverter via "PKW data".
– PZD: The inverter receives control commands and setpoints from the higher-level
PROFIdrive and telegram numbers
For typical applications, certain telegrams are defined in the PROFIdrive profile and are
assigned a fixed PROFIdrive telegram number. As a consequence, behind a PROFIdrive
telegram number, there is a defined signal composition. As a consequence, a telegram
number uniquely describes cyclic data exchange.
The telegrams are identical for PROFIBUS and PROFINET.
