here is my setup. DL06 plc 8 " c-more screen. Am logging 6 line trends to USB stick. It logged up to 23:59hrs (time) and now it does not start a new day. It seems that some how it just quit logging just when it was supposed to start a new file.I have about 5 days where it logged perfectly and now it just quit. Has this happened to anybody? The USB stick was formatted beforehand and hardly has any files on it. Any ideas would be appreciated.

Chances are, all of your trend files have the same first 3 letters. The filing system in CE uses the old DOS file name restrictions, so if the trend is Trend 1, the Trend file name you see is:
Screen 1_LineTrendGraph1
Screen 1_LineTrendGraph2
Screen 2_LineTrendGraph1
Screen 3_LineTrendGraph1
but internally they are named:
Scr~001.txt
Scr~002.txt
Scr~003.txt
Scr~004.txt
If you have a lot of trends on one screen, and/or the screen names have the same first 3 letters, then you quickly get to
Scr~999.txt
When you get to here, there are no more unique file names for that directory and presently C-more it will not overwrite the old files.
So the solution is to change the Screen names so that the first 3 letters of the file names are different.
Pump House_LineTrendGraph1
Pump House_LineTrendGraph2
Mezzanine_LineTrendGraph1
Basement_LineTrendGraph1
Then the internal file names become:
Pum~001.txt
Pum~002.txt
Mez~001.txt
Bas~001.txt
If this is not the situation, please contact Technical Support
