Communicaon me
The communicaon me is the me between the start of a request and the arrival of the cor-
responding response.
The communicaon mes in the PROFIBUS network depend on the ...
•
processing me in the inverter
•
Telegram runme (baud rate/telegram length),
•
nesng depth of the network.
In the case of the inverter, the processing me for process data is approx. 2 ... 3 ms, and for
parameter data (DPV1) it is approx. 10 ms. There are no interdependencies between parame-
ter data and process data.
