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 device. 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.
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 a device or feeder selected in the Viewer. The SCADA Summary displays the following fields and buttons:
• The Feeder column contains the name of the feeder reporting the SCADA measurements.
• The Substation column contains the substation name.
• The Device column contains the name of the device 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, Inhibit, Manual Override, or Disabled in Power Flow). 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 device status.
• The User column displays the name of the user who entered/modified comments when changing the device status.
• The Date column displays the date and time when the comment was entered or modified.

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 Device
To open the SCADA Summary for a specific device, select the device or feeder in the Viewer and launch the Control Tool. Click SCADA Summary... and select one of the options:
• Device...: loads the SCADA Summary with the SCADA measurement data for the selected device.
• Feeder...: loads the SCADA Summary with SCADA measurement data for the selected device's feeder.
• Substation...: loads the SCADA Summary with SCADA measurement data for the selected device's substation.
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 device 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 device 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. For example, you may need to enter fault current and fault indicators to trigger Fault Location Analysis (if applicable). See Chapter 20, Fault Location Analysis for more information.
If the value for the selected measurement is a switch 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 devices 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 switch 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 device, it only blocks the value reported by the SCADA device 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 Inhibit or Disable in Power Flow actions, 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 device's SCADA Summary row.
Existing comments may be edited by selecting the SCADA Summary row and selecting Edit Comment... from the Actions menu.
Disabling/Enabling Measurements in the Power Flow Solution
If you see anomalies in the SCADA data (for example, due to mapping issues, transducer issues, or temporal issues, and so on) where SCADA values seem potentially unhelpful in allowing FLMService to solve, you can disable the suspected measurements from taking part in the power flow solution by doing the following:
1. Select the suspected measurements in the SCADA Summary.
2. Click the Disable in Power Flow button from the Actions menu or the right-click option menu. The Quality column value will be set to S for the selected measurements.
To re-enable the disabled measurements:
1. Select the disabled measurements from the SCADA Summary Tool
2. Click the Enable in Power Flow button from the Actions menu or right-click context menu. The Quality column value will be changed from S to blank for the selected measurements.
