4.2 Protocol data
4.3 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 PROFINET network depend on the ...
• processing time in the inverter;
• telegram runtime (baud rate / telegram length);
• nesting depth of the network.
processing time within the inverter
The times specified apply if the TCP/IP channel of the communication module is not used
(»Engineer« communication, chapter Setting the IP configuration ( 37) ).
There are no interdependencies between parameter data and process data.
Range Values
Process data words (PCD) Maximally 32 process data words (max. 64 bytes)
PROFIsafe message 4 words (8 bytes)
Acyclic parameter data channel Limited by the PROFINET frame size
