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.
