EL6731 Statistics
Since the PROFIBUS MC slaves should always be added to the EL6731 first, they are always addressed
before the DP slaves in the DP cycle. This part of the DP cycle is referred to as Equi cycle below. If the Equi
cycle exceeds the To time of the MC slaves, the last MC slaves at the EL6731 will usually get a
synchronization error (error 597 or 598 for Simodrive 611U).
max. repeats/equi cycle
This will show the maximum number of repeated Data_Exchange telegrams during an Equi-Cycle. This will
extend the Equi-Cycle, usually no repetitions should occur (unless a bus plug was pulled or an MC slave was
switched off).
min./max. equi cycle
Here, the minimum or maximum Equi-Cycle Time is displayed.
Equi cycle repeat counter
Here, the number of telegram repetitions within the Equi-Cycle is displayed.
Equi Cycle NoDxch Counter
Here, the number of occurrences is displayed, for which not all MC slaves were in data exchange during an
Equi-Cycle.
