Environment
Power Monitoring Expert (PME)

SQL Server Management Studio (SSMS)

Cause

ATS monitoring devices' data points are assigned to normal, test, and emergency in the PME Generator Performance Configuration Tool. If the data for all three of these data points is either 1) not logged, or 2) the data points are not correctly assigned in the tool, the report cannot show accurate test data for the ATS source.

Resolution

1. Open to the Generator Performance Configuration in the Power Monitoring Expert > Configuration Tools folder on your desktop or in the location C:\[PME Installation Folder]\system\bin.
2. Navigate to the Transfer Switches tab and select the transfer switch causing the issue.
3. In the "Status Measurements" area, ensure the source is correctly selected, and that the normal, test, and emergency data names in the combo-boxes have logged data for the selected source.
4. You can verify this by using SQL Server Management Studio (SSMS). Replace the text GroupName.Name with your source name as it appears in the source combo box. Replace the text for normal, test, and emergency with the names that appear in the combo boxes below. If the results show data for all three of the measurements for one test, it is valid and should appear in the report. If any of the three data points is missing for a run, it is not valid.
   

   USE ION_Data;
   
   SELECT 
       d.*, 
       s.DisplayName AS SourceName, 
       q.Name AS QuantityName
   FROM dbo.Datalog2 AS d
   INNER JOIN dbo.Source AS s ON d.SourceID = s.ID
   INNER JOIN dbo.Quantity AS q ON d.QuantityID = q.ID
   WHERE s.DisplayName = 'GroupName.Name'
     AND q.Name IN ('Normal', 'Test', 'Emergency');
   

5. The source may have logged the data under a different name then what was specified in the tool. Once it is determined, it needs to be corrected in the tool. After it is correct, hit 'Apply' and the Run History will refresh.
