Use the Maintained push button object to create a button that toggles between two values. This type of button is useful for changing a setting within a machine or process, but not for starting the machine or process.
A Maintained push button sends one value to the data source the first time it is pressed, and a second value the next time it is pressed and released.
Important: |
Do not use push buttons for emergency stops. Emergency stop buttons must be hard-wired. |
