4.3 Protocol data
4.4 Communication time
The communication time is the time between the start of a request and the arrival of the correspon-
ding response.
The communication times in the PROFINET network depend on the ...
• processing time in the inverter;
• frame runtime (baud rate / frame length);
• nesting depth of the network.
Processing time inside the inverter
There are no interdependencies between parameter data and process data.
