Bus cycle ≤ ≤ ≤ ≤
DP cycle
3-6
To ensure that the data transfer is synchronized the bus cycle time should
always be less than or equal to the DP cycle time.
The parameter min_slave_interval = 3ms is located in the GSD-file.
In an average system it is guaranteed that the PROFIBUS data on the bus
is updated after a max. time of 3ms. You can therefore exchange data with
the slave at intervals of 3ms.
Note!
Starting with release version 6, the RUN-LED of a DP-V0 slave extinguishes
as soon as the Bus cycle lasts longer than the DP cycle. This function is de-
activated at the employment of a DP-V1 slave as DP-V0.
