I have recently had very in-depth experience with PanelView Plus terminals and their Alarm Log files.
I think you're asking about the Data Log files themselves, which are created by the Data Log Model for use by Trend objects. The principles are similar.
The Knowledgebase article you're probably looking at is
AID # 33924, RSView Enterprise Log File Viewer (Access Level: Everyone).
Get a current copy of that article; the utility has recently revved up to 1.90 and the instructions have changed slightly.
My terminals were a few years older than yours (PV+1000, running 5.10.03 firmware), and of course I'm looking for the *.ALM files rather than the *.LOG files.
To get those files off the PanelView file system, I use a USB thumb drive. You can use a CF card or SD card as well.
I used a batch file on a USB thumbdrive to extract the log files from my PanelView. Mine is an old Corsair Flash Voyager, 8 GB, formatted for FAT16 so that the PV+ can see it. I used Windows Notepad to create a text file on the flash drive root directory named 'autorun.bat', which contains these four lines:
Where 'Sandpounder_rev32' is the application name I'm running on the PV+.
When I plug in the USB thumbdrive to the PanelView, the batch file runs and the 'Pocket CMD' window pops up in the foreground for a few seconds. When the window closes, I remove the thumb drive.
You can do this with an CF card or SD card as well, depending on the type supported by your logic module. If you have a model of PV+ that allows desktop access and FTP access to the file system, you might be able to do this over FTP as well; I have not tried.
There's another Knowledgebase article, AID 35513 (TechConnect Required), that gives us the important information about the path to the *.LOG files, rather than the *.ALM files. Use these copy statements with appropriately substituted Application names and Data Log Model names in your batch file.
For PV+ 5.10 and older:
For PV+6 and newer:
