golzione Posted September 30, 2019 Report Share Posted September 30, 2019 Hi All, I'm using a VT570 to log some data to SD card. I realized a single Trend with 2 curve for 2 sensor. My goal is to log on a monthly basis this data on a file. File name is "MMYY.utr". Sample rate is 1 data every 5 minutes. When I export data from SD to Excel using the appropriate tool I always have DateTime column rollback in a strange way. All the datetime are correct till to 25th of month and then they are wrong (even if the logged data continues to be correct). Here under you can find some screenshots that I hope explain the issue better than my words. Ladder code is simply and It is essentially a copy of Visilogic example to save Trend on SD Card but I'm not able to understand where is the error. Any help or advise will be very appreciated.
