6.1.3 Communication times

Tip!
The communication time is the time between the start of a request and the
arrival of the corresponding response.
The PROFIBUS communication times depend on:
ƒ Processing time in the controller
ƒ Transmission delay time
– Transmission rate (baud rate)
– Telegram length
Processing time in the motor starter
The parameter data and process data are independent of each other.
ƒ Parameter data: approx. 30 ms + 20 ms tolerance
ƒ Process data: approx. 3 ms + 2 ms tolerance
ƒ PROFIsafe
The PROFIsafe communication time depends on the PROFIsafe cycle time. This time is
defined by the F-CPU. It depends on the F-WD time that is set and on the set cycle time
of the monitoring OB in the control.
ƒ PROFIsafe process data in the motor starter:
– F-input data: max. 14 ms
– F-output data: max. 24 ms
