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 INTERBUS 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
There are no interdependencies between parameter data and process data.
Range Values
Process data words 0 ... 10 words (16 bits/word)
Parameter data words 0, 1, 2, 4 words (16 bits/word)
The parameter data is transmitted in accordance with the Peripherials
Communication Protocol (PCP).
