4.5 Communication time
The communication time is the time between the start of a request and the arrival of the
corresponding response.
The communication times depend on ...
ƒ
the processing time in the controller
ƒ
the transmission delay time
– the baud rate
– the telegram length
Processing time 8200vector / 8200motec / starttec
There are no interdependencies between parameter data and process data.

Parameter data: approx. 30 ms + 20 ms tolerance
