Limit Switch Issue

Hello,

We are currently trying to program our limit switch so that it limits the range of our arm (we have it so that when the arm hits the switch, the arm will be unable to move against the switch).

We have all the logic and programming finished, but the limit switch is always returning a true value. We have checked the wiring many times but the switch always shows up as a true value.

We are opening the DIO and getting the value from the DIO Get, and we tested the switch many many times, and unfortunately it always gives a true value, even if the switch is being pressed or not pressed.

Things we did: Changed Switches, Rewired, Changed Slots, Tested Switch with an indicator and a probe.

The switches were actually working (electrical test), they registered a value of true or false. However, the DIO shows up as always true in the labview reference get.

Any help on debugging this issue would be very helpful!
