Thank you 😄

everything works now.

you should recognize the posts w kudos that has helped you and or have given you a solution...otherwise, it was all done in vain

did you take the suggestion that Sir RavensFan had mentioned? from what i see from your last vi post....

• you have only 2 case statements for (0,1) or "hold" and ""right", both of which are (F,F) bool arrays?

i suggest you change the "hold" array to (T,T) and the "right" to (T,F) and add a third case (#2) the "left" to (F,T),....

• so we 3 cases (0,1,2) matching cluster order of the buttons with respects to (hold, right,left) with bool arrays[ (T,T),(T,F) and (F,T)]

When I try to run each valve of the solenoid separately, it works and runs fine. However, when I try to run both valves on the parallel circuit (Darlington pair firing circuit), it appears to be working, as I can hear the "switching" sound, but it does not move the cylinder. What could be the source of this problem? I'm not sure if it is a problem in the circuit, or the program.

Thanks!

Does the power source for the valves have a high enough current rating to power two valves at once?

yes there is enough current raiting

both ON means HOLD, correct?

[Elmira]

That's correct
