LabView button for a double-acting cylinder

[smcmahon]

OK...

So, because I don't have any other idea how to do it, I was going to wire (electrically) the two red/black sides of the two solenoids to two seperate connections. Either two of the "pneumatic bumper" relays or two Spike relays.

Where do I put those two connections, in this LabView code, and how does it differentiate which one to energize/fire?

You keep track between loops which one was the last one to fire. You can have something like the code I posted before keep inverting a boolean value, and depending on that value, power the solenoid (in a case statement).

Like, if value is true, power A and not B. If value is false, power B not A.

And then you use the button code to change the value back and forth between true and false.

It hard part it wrap your mind around is using a momentary button as a latching switch..
