Itzik Posted June 13, 2018 Report Share Posted June 13, 2018 Hi. I'm using the "Strt trnd ->SD" to write trend data to SD card. I can see that the first time of writing and reading to/from the card is O.K and I can see the data on HMI. The file size on the sd is very small (5K) even the sample is every 1 min. and the process lasted for 3.5 hours. At the second time, after few hours (my process is very long) after about 5 hours, when i stop saving to the card, the "In Progress (OFF at Stop Trend): Start Trend->SD" remains in 1, and when i try to read from the card i get the "Trend load error bit". when i look in the SD with the SD manager, i see only the 1st Process trend and nothing from th 2nd process. Please Advice. Itzik 30000000.UTR Link to comment Share on other sites More sharing options...
Saragani Posted June 13, 2018 Report Share Posted June 13, 2018 Maybe you are not appending to the file, but overwriting it? It's been a while since I last used the SD elements on VisiLogic. Link to comment Share on other sites More sharing options...
