Hi Uzi,
then I strongly recommend to use Workshop #10.
This WS by Norbert Burkert describes
- modifying the Märklin turntable to use a feedback contact
- connecting the turntable to the IB
- draw and configure the turntable within WDP to use for e.g. timetable operations.
If you modify your turntable as described in the WS, you can use standard feedback contacts like e.g. S88 or derivate.
Regards
Rüdiger
