Figure 6-11 Telegram structure
A telegram has the following structure:
● Header and trailer form the protocol frame.
● User data is located within the frame:
– PKW: The control system can read or change the parameters in the converter via "PKW
data".
Not every telegram has a "PKW range".
– PZD: The converter receives control commands and setpoints from the higher-level
control - and sends status messages and actual values via "PZD data".
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.
