OK. I confess. I have no idea what I am doing when it comes to trying to get WD to work with my VP/Datalogger.
I know there are some problems when the logger file is full, but this problem showed up a couple of weeks ago.
First of all, My VP and computer are within 30 seconds of the same date and time. I am logging at 1 minute intervals. I am using 10.12q
When I re-start WD after having the computer down for a half hour or so, and then restart WD, it loads data from up to several hours BEFORE I shut down WD. This data gets appended to the log and my graphs show time repeating itself, i.e. the time axis says 8, 9, 10, 9, 10, 11 etc.
Today, I had a 1 minute power failure that nocked my usb/serial converter out, shutting down comunications from the VP to WD. Both continued to run, but I got flat line graphs at the last known VP readings.
When I restarted the computer to reset the usb/serial adapter, WD started to read the datalogger from two days ago when I last started WD. I aborted that session and re-started again. Now it read in only the last couple of minutes of data. I then went to the action menu and manually extracted data from the datalogger. This appended to the existing data and I have duplicated records. Actually triplicated since the first time I extracted, it did not seem to work.
When I get the screen to manually extract, there are 3 options. Restart my own custom log, append to WD’s logs, and Restart WD’s logs. I am afraid to use the restart option because I don’t know if that will wipe out all of my logged history. So when I did the extraction, I did not check any of the boxes.
What am I doing wrong? Is there a problem with the extraction process? Is it possible for me to edit the logs and correct my data?
I know everyone out there with VP stations have the datalogger. Oh, I have rev B if that means much.
As of this event, I have unchecked the option to download when WD starts. I figure I will control that manually. But I need to know how to use the manual extraction correctly so the data gets “inserted” into the correct location in WD’s files, and not appended as is currently happening.
Inquiring minds need to know. :?:
