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.
) on the bar above the table, the table will be repopulated with all measurements and the bar will be removed. Loading SCADA Summary Data for a Different Asset
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
The Override Limits dialog 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.
The SCADA Trend Graph tool displays historic or real-time trend lines for up to 9 SCADA measurements as long as there are no more than two distinct units of measure (for example, Amps and kW) between them.
The tool contains two main parts: the graph that displays trend lines and the Trends collapsible panel that contains the list of saved SCADA Trend Graph configurations.
Components of the SCADA Trend Graph
Trends Collapsible Panel
Contains a list of saved SCADA Trend Graph configurations accessible to the user. Each item has a unique name and represents a list of SCADA measurements, type of trend (real-time or historic), and date range.
SCADA Trend Graph configuration can be loaded by double-clicking on an item in the list or using the Load option from the File menu SCADA Trend Graph tool.
Graph Panel
For historic trends, the start and end dates can be changed by selecting a date and time in the Begin Date and End Date fields.
Real-time trending mode can be enabled by the Real-Time check‑box. In this mode, the Begin Date and End Date fields are replaced with the Time Window drop‑down list. Data is displayed for the selected time period going back from the current time.
Newly received values for the displayed measurements are added to the graph dynamically. The graph can show the predicted values and the actual measurements over the given period of time. If you hover the mouse over a point on the graph, the details of the measurement will be shown.
Exporting Measurements
To export measurements, select Export... from File menu in SCADA Trend Graph tool. The export Measurements dialog box will open.
Using Export Dialog Box
Export Dialog Box Fields
• Export Location: This refers to the location where we want to export the trends.
• Search Button: The Search button opens a Export Table dialog box that allows you to select the location to save the exported CSV file.
• Export Raw Check Box: If this check box is selected, it will export raw values of all the measurements displayed in the graph tool.
• The Measurements table displays the list of analog measurements that are currently displayed in the SCADA Trend Graph tool. The table contains two columns: the selection column (unnamed) contains check boxes used to select measurements, and the Name column contains measurement names.
Note: The table will only be visible if the raw check box is unselected.
Buttons
• The OK button saves the data to file and closes the dialog box.
• The Help button opens the online help for this topic.
• The Cancel button closes the dialog box without exporting the data.
