UNICO2 Posted June 6, 2017 Report Share Posted June 6, 2017 I use trends and they fill up the SD card on the UniStream. I tried to use the file browser object to manage the SD card. Specifically I'm trying to delete the 'samples' folder created by the trends. When I try using the file browser and UniStream SD Delete (or the one in UniApps) after selecting the 'samples' folder I get an error Quote File Operation Failed :Check if SD/USB storage device is OK Any ideas on how to do this correctly? Is something writing to the disk or not properly stopped? Right now I have to pull the SD card and delete it on my laptop then put it back into the PLC. Not very elegant and difficult to do remotely... Thanks! Quote Link to comment Share on other sites More sharing options...
Saragani Posted June 7, 2017 Report Share Posted June 7, 2017 Maybe the folder or one of the files is being used, You can try using File operations from ladder, if it is something you want to do in code, UniLogic 1.20 would support automatic file deletion of old files based on rules that can be configured by the user, so your samples folder would not get "exploded".

greml1n Posted June 12, 2017 Report Share Posted June 12, 2017 I had the same issue when I tried deleting. A reboot of the PLC cured it if I remember Quote Link to comment Share on other sites More sharing options...
