Tab: EtherCAT Master – DC Statistics

This tab is used to diagnose the DC data and shows the temporal behavior of the runtime systems. The frequency of time deviations (e.g. jitter) is recorded for this purpose.

Reset values to zero

Resets all counts to 0

Deviation [µ]

Time ranges of the deviations.

The deviation describes the time between the actual time of the next task call and the expected time of the next task call.

Here, <1 counts the deviations between 0 and 1 µs, <2 counts the deviations between 1 µs and 2µs, and so on.

Count (neg)

Number of negative deviations

Percent (neg)

Percentage of negative counts in relation to the total number of cycles counted

Percent (pos)

Percentage of positive counts in relation to the total number of cycles counted

Count (pos)

Number of positive deviations
