Renier Posted June 3, 2020 Report Share Posted June 3, 2020 Hi, I am using the 7" unistream and i have data samplers running and writing to the SD card. I first noticed that nothing is displayed on my trend and on further investigation I found the data sampler's status (in its own struct) to be "-3" which is listed as a "save file eror". I then tried to save a screen shot and it also failed. Strange thing is, i can still browse the SD card using uniapps. When i remove the sd card and insert it again with the plc running, it works fine. But when the plc is shut down and starts up again, it has the same problem. Does anyone have an idea as to what's going on or what i am doing wrong Thanks Quote Link to comment Share on other sites More sharing options...
Swervomotor Posted June 3, 2020 Report Share Posted June 3, 2020 When I have issues with the SD card I just replace the SD card, not saying that's your issue but a lot of SD cards now are crap out of the box or shortly after. 1 Quote Link to comment Share on other sites More sharing options...
