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 an POWERLINK 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
