4.3 Ethernet POWERLINK communication data
Communication time
The communication time is the time between the start of a request and the arrival of the
corresponding response.
The communication times in the Ethernet POWERLINK network depend on ...
 the processing time in the controller;
 the telegram runtime (baud rate / telegram length);
 the nesting depth of the network.
Processing time in the controller
There are no interdependencies between parameter data and process data.
