Control music volume with Busch-priOn

Example: Control music volume with Busch-priOn

Task

priOn is setup on group address 10/0/100 (data type 03.007 dimming control). How to make increase music volume by turning the central button clokwise.
Assuming that KNX group address 10/0/101 (data type 05.5byte unsigned integer) range is from 1 – 21 (5% volume increase on each number).

Event-based script

Add the following program which will trigger each time when the group address 10/0/100 on the priOn is activated with central button.

Note! Make sure that the object 10/0/100 is set to data type 3.007 and 10/0/101 to 5.001 in Logic Machine’s Objects tab.
