Activate the equidistance at the DP master system.
Set the length of the equidistant DP cycle (max. 32 ms).
Set Times Ti and To identical for all DP slaves (synchronizes the I/O data
of the various DP slaves).
Times Ti and To can be set separately.
Recommendation: Accept the default settings for Ti and To.

Note
If you click the Recalculate button, STEP 7 calculates a value for the equidistant
DP cycle; this value takes the current PROFIBUS-DP configuration into
consideration. The value is then automatically entered in the Equidistant DP
cycle, Time Ti (...) and Time To (...) fields.
