Hello
I'm new here and also my english is little bad bad I will try to explain my problem
I need to do a program in S7 GRAPH which controls the opening of the solenoid valves (SV) which are distributed on 4 pressure switches, there are 5 solenoid valves in each pressure switch(P).
I need to open one SV in each pressure switch (1,2,3,4,5) at the same MOMENT, but if for example pressure switch 1 (P1) is breakdown, this should not affect the operation of others, I need to open just one SV in each pressure switch Which are still available, another example, P2 and P3 is OFF but the others is ON so I need to open just one SV in P4, P5, P1, and not touch or open SV in P2 and P3 because they are breakdown (OFF).
How I will do this, I thought of the interlock or a branch OR but is a lot of cases to do if I use branch OR.
Awaiting your help
Thanks in advance
