Name of the valve record and its description.

Current state

This field indicates the current extended state of a Valve (For example, Open, Closed, Transit, Stopped)

Valve Type

This is the Configuration type of the valve set by the Administrator. This value may be either Physical, Logical, or Synthetic. If this value is Logical or Synthetic, it will be followed by a connection type of either Series or Parallel.

If the valve is configured as Synthetic, you will be unable to set the Logic Mode.

If the valve is configured as Logical, you will be unable to set the Logic Mode or send commands.

Parent Valve

This is the Synthetic or Logical valve to which this valve record belongs.

PLC State

This field indicates the Programmable Logic Controller (PLC) state of the valve.

Note: This field is only visible for Physical or Synthetic Valves. Logical valves do not have a PLC state, so the field is hidden.

Flow Path Dependents [Pump, Station, Flow Network]

This field lists information related to dependent pumps in the current flow network or in any interconnected flow network that would be blocked if the valve is closed. For each dependent, the Pump, the Station and the Flow Network is listed.

Dependent pumps are displayed in such a way that pump stations are ordered from the most upstream station to the most downstream station affected by the valve closure. For interconnected scenarios where multiple flow paths are concurrently active, pump stations within upstream interconnected Flow Networks will appear first, followed by pump stations in the Flow Network containing the valve of interest, and followed by pump stations within downstream interconnected Flow Networks.

Last Krunch

The date and time that the current state was last calculated.

Logic Mode

Determines how the valve appears to any Flow Networks it is a member of. There are four possible states:

• In Service: Default state. Select if the valve should be used normally within any flow networks to which it belongs.

  An In Service valve may be designated critical by the applications that are using the information that the valve provides, if closing the valve could cause a problem elsewhere.

• Out of Logic (OOL): In this state, the valve is operable and the status can be viewed, but changes of status will not execute any logic. This state would be used for pressure management.

• Out of Service Open (OSO): In this state, the valve is treated as if it is open. It displays the status from the field, but commands cannot be issued from this valve. This is useful when the field device is reporting an inaccurate state during maintenance or other failure conditions.

• Out of Service Closed (OSC): In this state, the valve is treated as if it were closed. Commands cannot be issued in this state. If a line blockage is created, the system will treat it as a valve closure and shut down the line section.

Select the desired description from the dropdown menu. To save your changes, select Set.

Open, Close, Stop

Note: Open, Close, and Stop are only enabled for Physical and Synthetic valves when they are In Service or Out of Logic (OOL), and the underlying status or multistate record's Has Output checkbox has been selected.

These buttons allow you to attempt to open or close the valve.

• When Close is selected, the Flow Network is checked to ensure that closing will not block any pumps or close off any paths.

  If closing the valve will cause a blockage as defined in the configuration, then a warning message will be displayed. At this point you may elect to override the message and send the command anyway, or you may Cancel.

• Additionally, if the valve is marked as being Out of Logic, a confirmation message will display to confirm that you wish to open or close the valve.

• When Stop is selected, the valve maintains its previous opening or closing state in any associated flow networks.

Event Summary

This is a list of all events associated with the valve and underlying status or multistate point. If the status or multistate record is not configured, this is a list of all events associated with the valve point.

Point Alarm Summary

This is a list of all current alarms associated with the underlying status or multistate point. If the status or multistate record is not configured, this is a list of all alarms associated with the valve point.

Tag Summary

Open the Tag Summary for the telemetry point associated with this valve. For more information about Operator Tagging, refer to the AVEVA Enterprise SCADA HMI Controller documentation.

Priority Display

Opens the associated priority display. For more information about the priority display, refer to the AVEVA Enterprise SCADA HMI Controller documentation.

Verification Control

Opens the Point Verification Control dialog. This allows you to enter Point to Point Verification results, create pending or approved verification records, and save the results to the CRM database.

Underlying Point Control

Opens the control panel for the underlying status or multistate point.
