Resolution

Configure the LogAcquisitionControl.xml file:
1. On the PME server, navigate to ...\Program Files (x86)\Schneider Electric\Power Monitoring Expert\config\cfg\logsrv.
2. Make a copy of the LogAcquisitionControl-Example.xml file, then open the copied file in Notepad.
3. Refer to the examples in the file and below to configure the file.
4. Save the file, then rename it to LogAcquisitionControl.xml. After a few seconds, the changes will be automatically applied to the system.

Note:

• DeviceName is the system name of the device in PME, which can be different than the display name shown in Management Console and other PME applications.
• PollingInterval can be any number between 1 and 60. This polling interval is how often PME checks for new onboard logs to upload, it is not the polling interval that is set onboard the device.

Example LogAcquisitionControl.xml file:

PollingInterval is now set to 15:

Polling is now disabled for the 0xf80 and 0xf8a data recorders:

How to find the DeviceName (system name) of a device in PME:
1. Open SQL Server Management Studio and connect to the PME SQL server.
2. Click New Query.
3. Copy/paste the following script into the Query Editor window, modifying the text Group.DeviceName highlighted below with the name of the source as shown in PME:

USE ION_Data
SELECT Name FROM Source
WHERE DisplayName = 'Group.DeviceName'

How to find the LogHandle ("Recorder H") of a data recorder:
1. Open SQL Server Management Studio and connect to the PME SQL server.
2. Click New Query.
3. Copy/paste the following script into the Query Editor window, modifying the text Group.DeviceName highlighted below with the name of the source as shown in PME:

USE ION_Data
SELECT Recorder.Label, RecorderState.LogRegister
FROM Recorder
LEFT JOIN RecorderState
ON Recorder.ID = RecorderState.RecorderID
WHERE Recorder.SourceID IN (SELECT ID FROM Source WHERE DisplayName = 'Group.DeviceName')
ORDER BY Label ASC

4. Refer to the Label column to find the data recorder, then note the value in the LogRegister column.
5. Convert the value in the LogRegister column to Hex.
6. Enter it in the LogAcquistionControl.xml using the format: <Recorder H="0x(hex value from LogRegister)"
