Pushbutton doesn't write to tag bound to it

Ignition

I am creating a button to remotely start a machine. The machine's program has the tag bound to the pushbutton. I tested the logic by toggling the tag "HMI_RUN_DAF_PB" on in the PLC which did turn the machine on. The state of the pushbutton in Ignition Designer changed with the toggling of the tag. However when I pressed the pushbutton in the Ignition Vision window nothing happened. I actually tried several button styles bound to my tag - still nothing.

Did you make your binding on the button bidirectional?

If that doesn't fix it, what type of button is it and what property are you binding to?

PLC tag could also be set to read-only, but that doesn't sound likely.
