Objects 3A10h to 3A12h generate three statistics signals.
Sub-index 50 ... 55 Corresponds to the command META_STATISTICSIGNAL.
Sub-index 6 corresponds to the STATISTIC command.
3 signals are generated for each statistics object activated. They are listed in object 0x3E00. The statistics function can
also be applied to user signals.
Example: You want distance 1 (channel 1) to output the minimum and the maximum measured values using all previous
distance values.
Activating a statistics object
3A10:01(Enable) to TRUE. Distance 1 (01DIST1) is selected as signal by default. If you would like to display statistics for
a different signal, you will need to select the required signal in sub-index 2.
- Settings for all previous distance values
3A10:04 (Infinite) to True (STATISTICSIGNAL – INFINITE)
Assigning a user-defined signal to the PDO
The newly generated signal names appear in object 0x3E00h:
The minimum distance is output in 0x7C00h and the maximum distance is output in 0x7C02h.
Select PDO
UserCalcOutput01 – 0x7C00h is selected with object 1B00h, and 0x7C02h is output with object 1B10h

Therefore, the following selections need to be made in 0x1C13h, 0x1B00h and 0x1B10h before PreOp is switched to
