Changing Data Values
The following section describes procedures that relate to modifying data values for analogs and status points.
If a modified value is rejected after you complete any of the procedures in this section, it may be for one of the following reasons:
The value might need to be put in the “Not In Service” state.
The value is normally supplied by the State Estimator.
You attempted to enter a null value.
You entered a value outside of the reasonability limits.
Manually Overriding Point Values from a One-Line
To remove a point from service and enter an operator override:
- On a one-line, select the device symbol.
A pop-up box appears.
Click the Remove button.
The “not in service” symbol appears next to the button.
Click the Select button.
The toggle button on the pop-up becomes available for use.
Click the override or toggle button.
If the override button is selected, the device status remains the same. If the toggle button is selected and the device status is currently OPEN, it changes to CLOSED; if the toggle button is selected and the device status is currently CLOSED, it changes to OPEN.
Click the Done button.
The pop-up disappears.
Note that the “manually replaced” symbol appears next to the device on the one-line, indicating that the status has been manually overridden.
Manually Overriding Point Values from a Tabular
To remove a point from service and enter an operator override:
- On the Substation Tabular display, the Point/Analog/Count view, click the Not In Service button for the desired point.
The Not In Service flag is set for the point, as can be seen by selecting the point’s Flags button.
From the point’s Value button pop-up menu, select the Override or Toggle option.
If the Override option is selected, the value remains the same and the Data Quality field reads “Replaced”. If the Toggle option is selected, the value changes from OPEN to CLOSED (or vice versa), and the Data Quality field reads “Replaced”.
The Flags pop-up shows that both the Manually Replaced and Not In Service flags are set.
Manually Overriding Analog and Count Values from a One-Line
To remove an analog or count from service and override its value:
- On the one-line, select the Analog field.
A pop-up box appears.
Click the Remove button.
The field containing the analog value becomes enterable.
Position the cursor on the field containing the value, type in the new value, and press the Enter key.
The entry is accepted if you have permission for entry and the value is within the reasonability limits. If not, the entry is rejected.
Click the Done button.
The pop-up disappears.
Note that the analog’s value has changed on the one-line, and that it is accompanied by a “manually replaced” symbol.
Manually Overriding Analog and Count Values from a Tabular
To remove an analog or count from service and override its value:
- On the Substation Tabular display, click the Not In Service button for the analog.
The Not In Service flag is set, as can be seen by clicking the analog’s Flags button.
Select the Value field for the analog.
The field becomes enterable.
Type a new value into the analog’s Value field, and press Enter.
If the value is accepted, the analog’s Data Quality changes to “Replaced”.
The Flags pop-up shows that both the Manually Replaced and Not In Service flags are set.
Removing Manual Override and Restoring a Value to Service
As the previous sections indicate, when a value is manually overridden, both the Manually Replaced and Not In Service flags are set for the point, analog, or count involved.
The following action removes both flags from the point, analog, or count, and causes the value to be replaced with the next scanned value. If the point, analog, or count has simply been removed from service without having its value manually overridden, the following action simply returns it to service.
On the Substation Tabular display, click the point, analog, or count’s depressed Not In Service button.
The point, analog, or count is restored to Scan. On the tabular display, the point, analog, or count’s Data Quality field no longer reads “Replaced”, and its Not In Service flag is removed (as can be seen by clicking the Flags button).
Mass Remove from Service/Restore to Service for an Entire Substation
This procedure describes how to remove all measurements on a substation from service, or restore all measurements on a substation to service. Each analog, count, and digital status point that is modeled in that substation is marked as Not In Service (self quality flags).
Mass-Remove/Mass-Restore is a toggle-type action. That is, the Not In Service button is toggled between “In Service” and “Out of Service” each time this procedure is performed.
- Call up the Substation Tabular display, and click the Action Options button.
The Options pop-up appears.
From the Options pop-up, select either Mass Remove From Service or Mass Restore To Service.
All analogs, counts, and points modeled on the substation are either removed from service or restored to service (the Not In Service self flag is cleared on each record).
Mass Remove from Service/Restore to Service for an Entire Bay
This procedure describes how to remove all measurements on a bay from service, or restore all measurements on a bay to service. Each analog, count, and digital status point that is modeled in that bay is marked as not in service (self-quality flags).
Mass-Remove/Mass-Restore is a toggle-type action. That is, the Not In Service button is toggled between “In Service” and “Out of Service” each time this procedure is performed.
- Call up the Substation Tabular display.
- Call up the Equipment Group display, and click the Action Options button.
The Options pop-up appears.
From the Options pop-up, select either Mass Remove From Service or Mass Restore To Service.
All analogs, counts, and points modeled on the substation are either removed from service or restored to service (the Not In Service flag is cleared on each record). Note that this action updates the self-quality flag.
Remove from Service / Restore to Service for a Bay
This procedure describes how to remove a bay from service, or restore a bay to service. If the hierarchical actions are enabled for this type of bay, each analog, count, and digital status point that is modeled in that bay is marked as Not In Service (hierarchical quality flags).
- Call up the Substation Tabular display.
- Call up the Equipment Group tabular display, and click the Not In Service button.
If the hierarchical actions are enabled for that type of bay, all analogs, counts, and points modeled on the substation are either removed from service or restored to service (the Not In Service hierarchical flag is cleared on each record).
Bypass Entry of Point Values from a Tabular
If a point is reported from a remote site or from the SCADA Front End with a Suspect Data Quality, the operator can bypass the normal value and temporarily replace the value. The point is not removed from service.
When a value is reported from the remote site or SCADA Front End with good quality, the good quality value automatically takes precedence over the temporary value entered by the operator.
This procedure is used to “Bypass Enter” a point from the Substation Tabular display:
- On the Substation Tabular display, the Point/Analog/Count view, select a point that has Suspect Data Quality reported from a remote site or SCADA Front End.
From the point’s Value button pop-up menu, select the Override or Toggle option.
Note that, for bypass entry, the point should not be removed from service.
If the Override option is selected, the value remains the same and the Data Quality field reads “Bypassed”. If the Toggle option is selected, the value changes from OPEN to CLOSED (or vice versa), and the Data Quality field reads “Bypassed”.
The Flags pop-up shows that both the Manually Replaced and Bypassed flags are set.
Bypass Entry of Analog and Count Values from a Tabular
If an analog or count is reported from a remote site or from the SCADA Front End with a Suspect Data Quality, the operator can bypass the normal value and temporarily replace the value. The analog is not removed from service.
When a value is reported from the remote site or SCADA Front End with good quality, the good quality value automatically takes precedence over the temporary value entered by the operator.
This procedure is used to “Bypass Enter” an analog from the Substation Tabular display:
- On the Substation Tabular display, the Point/Analog/Count view, select an analog that has Suspect Data Quality reported from a remote site or SCADA Front End.
Select the Value field for the analog.
The field becomes enterable.
Type a new value into the analog’s Value field, and press Enter.
If the value is accepted, the analog’s Data Quality changes to “Replaced”.
The Flags pop-up shows that both the Manually Replaced and Not In Service flags are set.
Commissioning and Uncommissioning Measurements
When a status point, analog point, or accumulator point is retrieved into the online model from the offline model for the first time, it may be marked as “uncommissioned”. When a measurement is marked as uncommissioned, it is considered a point for which the associated telemetry has not yet been provided, and it is also marked as Not In Service. Uncommissioned points are displayed separately from Not In Service points, which are not marked as uncommissioned.
An analyst can commission a measurement into service, or de-commission a measurement from the substation tabular Analyst Details popup display.
This procedure is used to commission a point into service:
- On the Substation Tabular display, the Point/Analog/Count view, select the Details icon to bring up the Analyst Quality Flags pop-up display.
The console must have write access to the ANALYST area of permission to support this functionality.
Click the Uncommission Data Attribute button to commission a previously uncommissioned measurement, or to de-commission an in-service measurement.
