Hello everyone
FIRST of all, sorry because I did not write in german but I need some help please
I'm new here and also I studying automation and I want some help in interlock in s7 graph, so my problem is I want to do conditional actions in a single STEP, as in this image

I can do this if I have just one action, But in my case I have 4 actions and I need In one step doing 4 actions conditional, so there is my case

and want to execute OPEV12 if P1 is actived , OPEV72 if P7 is actived , OPEV102 if P10 is activated, OPEV42 if P4 is activated, I want to do this in one step with using INTERLOCK, and like the first picture. here are more details :
If P1 ON
P4ON
P7 ON
P10 ON
-------> execute this actions: OPEV 12 and OPEV72 and OPEV102 and OPEV42 at the same time
If P1 OFF , P4 ON , P7 OFF , P10 ON
-----> execute just OPEV42 and OPEV102
If P1 ON , P4 Off , P7 OFF , P10 OFF
-----> execute just OPEV12.
etc.... so I have a lot of cases depending to P1,P4,P7,P10, that why I prefer conditional actions (interlocks) , I can use alternative branch but if I use alternative branch I must to do 16 alternative branchs !!
Awaiting your help
