Meeg Posted May 27, 2016 Report Share Posted May 27, 2016 Hello. I have a problem that might be related memory capability in the SDcard. Suddenly (after a Power Off/Reset) all my trends stopped. When I open the trend it is empty and the Run/stop button displays Run. If I press the Run button nothing happens, but I am still able to open and view the "History" trends. Also all my trends had status -3; Save file error (File name may contain illegal character) (my file names are the same as when the trends was working). In my Project I use 12 data samplers/trends, 4-8 REAL variables in each trend, sampling interval 1s - 1min.The trends had been running for several weeks when the problem occured. After I changed my SD card to a new (empty) one, the trends worked again. So I assume that the problem was related to running out of memory on the SD. My SDcard is 16GB Do I have to delete history files from the Unilogic program to avoid running out of memory, or is this automaticcaly handeled by Unilogic? If I have to do it from the Unilogic program, do you have any examples on how to do this? Thanks! Quote Link to comment Share on other sites More sharing options...
