LabView button for a double-acting cylinder

[smcmahon]

Good morning.

We've got a double-acting cylinder in our pneumatic system. In our test code, we have two separate buttons that electrify either end of the SMC double solenoid. So, when we press one button, the cylinder extends. The other button causes the cylinder to retract. So far so good.

We're trying to think of a way to program that all into one button. So that, assuming it's retracted at the start, pressing the button once would extend it. The next press would retract it. Etc etc etc.

Is there any way to use a toggle button feature to accomplish this? Or some sort of Boolean expression chain?
