    • Operator/Maintenance online commands:
      The commands are enabled when online with the controller and the valve and instruction are ready for the command to initiate. The valve immediately responds to the command unless the operator must confirm the command. If the command request requires a signature, this will enforce security from the HMI and disable the command from the Logix Designer dialog.
