Configure PVLV instructions

Use the
Advanced
 tab on the
PVLV Properties
 dialog box to configure Process Valve (PVLV) instructions.
To configure PVLV instructions
  1. On the instruction in the routine, perform one of these actions:
    • On the Ladder or FBD instruction, select .
    • In the Structured Text editor, right-click the tag name and select
      Configure <tag name>
      .
  2. Select the
    Advanced
    tab.
  3. Configure these settings:
    • Valve type
      . Select the valve object type.
      • Solenoid
      • Motorized
      • Hand
    • De-energize output on
      : Select the conditions that trigger an alarm and stop the valve. Each condition sets a shed latch that requires a reset. Clear the checkboxes to configure the conditions to trigger an alarm but do not stop the valve. The Interlock condition cannot be unchecked. An Interlock Not OK condition always stops the valve.
      Use the
      HMI > Command configuration
       tab to define labels for the
      On loss
       checkboxes.
    • In override, bypass interlocks and permissives that can be bypassed
      . Enables override mode to bypass all bypassable permissives and interlocks. Clear this checkbox if always using permissives and interlocks.
    • Operator command resets fault
      . Enables operator commands to reset any previous faults and then move the valve.
    • External command resets fault
      . Enables external commands to reset any previous faults and then moves the valve.
    • Fail position 2
      (when energized after failure, move to position 1)
      . Defines the de-energized state of a spring-return valve. Use the
      HMI > Command configuration
       tab to define labels for positions 1 and 2.
    • Enable valve pulsing functions
      . Enables pulsing functions.
      • Valve pulse to state
        . Enables the valve to pulse to the requested state.
      • Finish pulse in progress when commanded position 1 or position 2
        . Finish a pulse in progress when the valve is commanded to move to position 1 or position 2.
    • Maintain output at state
      . Maintain output when the valve reaches the requested state.
    • Maintain output in alarm
      . Maintain output when the valve reaches the requested state and is in alarm.
    • Maintain stop output at state
      . Maintain stop output when the valve reaches the requested state.
    • Valve has trip output
      . Select if the valve has trip output.
    • Valve position 2 on trip
      . Enable valve position 2 when the valve is trips. Use the
      HMI > Command configuration
       tab to define the label for position 2.
    • Stop output can be used to break local seal-in and stop valve motion
      . Select if a stop output can be used to break a local seal-in and stop valve motion.
    • Coasting into limit switch when stopped changes state
      . Enable a state change when the valve coasts to a stop into a limit switch.
    • Operator command position 1 has priority
      . Gives priority to an operator command that moves the valve to position 1. Use the
      HMI > Command configuration
       tab to define the label for position 1.
    • Program command position 2 used as level
      . Select if program command to position 2 is used as a level (1 = Position 2, 0 = Position 1).
  4. When online with the controller, monitor the
    Device state
     and
    Device issues
     indicators at the bottom left of the dialog box:
    • Device state
      . Displays the current valve state, such as
      Pulse continuously
       or
      Out of service
      .
    • Device issues
      . Displays fault conditions, such as
      Feedback fault
       or
      Transit stall
      .
