Re: Help with debugging read of DIO

The switch is incorrectly wired.
Switches only use the signal and ground connections on the DIO. No power.
COM by convention connects to ground, but in the case of a switch it won't affect the workings.
The other two connections, NC (Normally Closed) and NO (Normally Open) are just two different choices for the signal that simply read the opposite of each other.

Remove the wire to NC.

As to the code, it seems to me that your boolean logic is reversed, because of the NO choice.
Try running in debug and probe the output of the DIO Get to see what value NO (Normally Open) returns.
