How the interlocked push button works at runtime

When the operator presses an interlocked push button, it changes from State 0 to State 1 and sends the button value to the data source. When the operator presses another interlocked push button, it changes from State 0 to State 1 and sends its button value to the data source, and the first button is set back to State 0.

When you open a display at runtime, including starting after a reboot, the application reads the Value connection. If the value matches the button value, the button is set to State 1. Otherwise, the button is set to State 0.
