Use the Latched push button object to create a button with a latched and unlatched state. This type of button is useful for starting a machine or process.
For example, use the Latched push button when you want the Value connection to start a process within a programmable logic controller (PLC) and remain set until the process is completed. You can also use a latched push button when you have a PLC with a long program or long update times.
Important: |
Do not use push buttons for emergency stops. Emergency stop buttons must be hard-wired. |
