Using the SCADA Summary
The SCADA Summary provides the current values and qualities of all mapped SCADA measurements in Oracle Utilities Network Management System. Each row of this summary represents one measurement. There may be multiple unique measurements on one SCADA asset. SCADA information includes digital and analog measurements, along with the quality codes and any user comments for each measurement. You can use the summary to view measurement information, manually replace current SCADA values, and inhibit updates. SCADA measurements can be assigned to network components or substation fences in the NMS model.
This section includes the following topics:
Understanding the SCADA Summary Window
The SCADA Summary may be opened to view all SCADA measurements or for measurements related to an asset or pressure zone selected in the Viewer. The SCADA Summary displays the following fields and buttons:
• The Pressure Zone column contains the name of the pressure zone reporting the SCADA measurements.
• The Lift Station column contains the lift station name.
• The Asset column contains the name of the asset reporting the SCADA measurements.
• The Value column contains the last reported measurement value. The value can be status, digital, or analog. For status measurements, the values are displayed as a test pair, such as open/close, on/off, and so on. Analog and digital values are shown as floating point and integer values.
• The Quality column contains the Quality codes for the measurement that indicates the quality of the SCADA measurement (for example, out of scan, inhibited, manual override). Several quality codes can be listed.
• The Point Name column displays the name of the SCADA measurement, as used in the SCADA system.
• The Attribute column contains a description of the measurement type, as configured in the ATTRIBUTES.description column in the Oracle Utilities Network Management System database for the matching attribute.
• Depending on your system's configuration, you may have the ability to enter comments when manually changing SCADA status (for example, Inhibitor Manual Override). See Adding and Modifying Comments for SCADA Status Changes for more information.
If this feature is configured, you will see the following columns:
• The Comments column contains the text of a comment entered when changing asset status.
• The User column displays the name of the user who entered/modified comments when changing the asset status.
• The Date column displays the date and time when the comment was entered or modified.
• The Limit Band column displays the current limit band for a measurement.
• The Limit Group column displays the limit group associated with the measurement.
• The Limit Set column displays the current limit set associated with the measurement. If the limit set has been overridden, this is displayed as Override.
• If the Flex SCADA license is enabled, then any calculations associated with a device will be displayed in the SCADA Summary. The following columns are applicable to calculations:
• The Source column indicates whether the calculation is a Calculated Measurement (a calculation whose value is written back to a SCADA measurement) or a Calculation (a calculation not associated with a SCADA measurement).
• The Calculation column contains the calculations definition.
• If the Flex SCADA license is enabled then an additional column pertaining to the Historian is available:
• The Historian column indicates whether the SCADA measurement reports its value to a long term Historian or not.

Viewing Data in the SCADA Summary
Viewing All SCADA Data
To open the SCADA Summary for all measurements, select SCADA Summary... from the Web Workspace Tools menu.
Viewing SCADA Data for a Selected Asset
To open the SCADA Summary for a specific asset, select the asset or pressure zone in the Viewer and launch the Control Tool. Click SCADA Summary... and select one of the options:
• Asset...: loads the SCADA Summary with the SCADA measurement data for the selected asset.
• Pressure Zone...: loads the SCADA Summary with SCADA measurement data for the selected asset's pressure zone.
• Lift Station...: loads the SCADA Summary with SCADA measurement data for the selected asset's lift station.
When the SCADA Summary is launched from the Control Tool, the data source is shown in a bar above the table.
Note: If you select Load All from the SCADA Summary Actions menu or click the X button (
) on the bar above the table, the table will be repopulated with all measurements and the bar will be removed.

Once the SCADA Summary has been opened (from the Control Tool), you can view data for a different asset by selecting it in the Viewer, and then clicking the Load button in the bar above the data table.
Preventing Measurement Updates
To prevent a SCADA measurement from accepting updates from SCADA, complete the following steps:
1. Select SCADA Summary... from the Web Workspace Tools menu. The SCADA Summary window opens.
2. Select a row in the SCADA Summary table corresponding to the asset measurement that you want to prevent from updating.
3. Click the Inhibit button.
Manual Entry and Override of SCADA Measurement Values
Occasionally, you may need to manually enter a status, digital value, or analog value for a SCADA measurement.
If the value for the selected measurement is a valve status measurement (that is, open/close), you must choose Show Control Tool... from the context menu to manually operate the switch. Otherwise, use the following procedure to enter a value manually:
1. Select SCADA Summary... from the Web Workspace Tools menu. The SCADA Summary window opens.
2. Select the SCADA measurement row in the SCADA Summary list.
3. Click either the Manual Entry or Manual Override button.
Note: Manual Entry allows future SCADA value changes to replace the manually entered value. Manual Override prevents SCADA measurements received by the system from changing the manually entered value. Manual Override can be useful when testing specific assets or RTU communications offline, since the test operations can be prevented from creating outages in Oracle Utilities Network Management System by putting manual overrides on the appropriate status measurements.
If the value for the measurement is a multi-state digital, analog, or any type of measurement other than a valve status measurement (open/close), a dialog box opens, allowing you to enter a value.
Note: Multi-state digitals are not available through the Oracle Utilities Network Management System SCADA ICCP Block 1, 2, and 5 Adapter.
4. Select or enter the value you want to change the measurement to.
5. Click OK.
Note: Clicking Manual Override blocks any new values coming from the SCADA measurement. It does not affect the physical SCADA asset, it only blocks the value reported by the SCADA asset to Oracle Utilities Network Management System.
Adding and Modifying Comments for SCADA Status Changes
When you change the SCADA state to Inhibit, Manual Override, or Disabled in Power Flow, you can enter comments to record why the state was changed. When you initiate an Inhibit action, a dialog box will open allowing you to enter a comment; for Manual Override, a Comment field is available below the Value field. The comment text, user, and date and time the comment was entered will be added to the selected asset's SCADA Summary row.
Existing comments may be edited by selecting the SCADA Summary row and selecting Edit Comment... from the Actions menu.

Understanding the Change Limits Dialog Box
The change limits dialog box allows you to change the current limit set for a single measurement (for example, from Spring to Summer). The dialog box displays the following fields:
• The Measure displays the selected measurement.
• The Limit Set allows you to select the new limit set from a list of limit sets associated with the group.
Buttons
• OK: Save the change in limit set and close the dialog box.
• Cancel: Cancel the change in limit set and close the dialog box.
Understanding the Override Limits Dialog Box
The Override Limits dialog box allows you to override one or more limit bands associated with the measurements limit set for a temporary period of time. The dialog box displays the following components:
• The Measure field displays the selected measurement.
• The Limit Set field contains the current limit set for the selected measurement.
• The Override Duration contains the duration of the override in hours and minutes.
• The Reason field allows you to enter a reason for overriding the limits.
• The Limit Bands table contains the current limit bands for the measurement. The table contains the following information for each limit band:
• The name of the band.
• The value of the band.
• The limit ref displays the reference measurement for this limit band if this band is an implicit or explicit reference.
• The reference type indicates whether this is a soft or hard reference.
• The description holds the description of the band.
See Understanding Limits for details on dynamic limit references and their types.
By default, the Limit Value will display a different background color based on the following events:
• dark red: The bands value is overridden.
• light red: The band is a reference to another measurement whose SCADA quality is bad.
• light green: The band is a reference to another measurement whose SCADA quality is good.
To override a band, enter a new value in the Limit Value column.
Buttons
• The Remove Override button will remove a previously applied override and return the limits back to their default values.
• The Apply Override button will apply the current overrides to the measurement for the specified duration.
• The Cancel button will close the dialog box with removing or applying any overrides.
Understanding the Historian Details Dialog Box
The Historian Details dialog box allows you to configure a SCADA measurement for reporting to one or more long term historians. The dialog box has the following sections:
Details Section
The Details section holds configuration applicable to all Historians and consists of two tabs: Details and Advanced.
• The Details tab contains the following components:
• Device: The name of the device associated with the measurement.
• Measurement: The name of the SCADA measurement.
• On Change Type: The trigger for reporting changes in value to the historian. Valid values are:
• On Change: Report the measurements value each time its value or quality changes.
• Periodic: Report the measurement value periodically.
• On Change and periodic: Report the measurement value on change and periodically.
• Period: If reporting periodically this is the time between each report.
• The Advanced tab contains the following component:
• Trigger on timestamp: Determines whether the value of the measurement will be sent to the historian even if the value and quality have not changed. This is reserved for IED's that report half hour periodic data as SCADA measurements and the value should be processed even if the value and quality remain the same between periods.
Interfaces Section
The interface section contains a tab for each enabled long term Historian.
• The PI tab contains the configuration details for the PI historian and contains the following components:
• Enabled: Whether the SCADA measurement is stored in PI or not.
• Reporting Enabled: Whether the value of the SCADA measurement should be reported to PI when it changes.
• PI Tag: The ID of the tag associated with the measurements value.
• PI Quality Tag: The ID of the tag associated with the measurements SCADA quality. If blank the quality will not be stored.
• Descriptor: The PI Descriptor for the measurement.
• Units: The units of measurement.
• Point Type: The PI point type
• Point Class Name: The PI point class name.
Buttons
The buttons section contains the following components:
• Save: Save any changes and close the dialog box.
• Help...: Invoke the on-line help for the dialog box.
• Cancel: Close the dialog box without making any changes.
For historic trends, the start date can be changed by selecting a date and time in the Begin Date fields. The end date can be changed by modifying the range drop‑down; the end date will be begin date plus range selected by user.
You can also use the previous and next button to change the start and end date.The maximum number of points displayed can be configured in the Max Points field.
The trend can be configured to source its data from a long term historian if one is configured in the system by selecting the Long Term check-box. Once selected, the Interpolation field is also displayed. The system will attempt to fetch the data from a long term historian for each SCADA measurement if they are configured to report to the historian. If they are not then the data will continue to be sourced from the NMS short term historian.
• If the Interpolation field is set to a value other than Raw then the Max Points field is no longer applicable and will be hidden. The data returned will be interpolated to the value specified in the interpolation field.
