curtharrington Posted August 17, 2012 Report Share Posted August 17, 2012 Hello, I am working on a project that requires recording the trending data from 4 separate trends to the SD Card. They want to record the data "no less than once every 5 minutes". I based my code off of the program in the examples file in the help menu and was able to get a single trend screen to record (I did it on the v570 for testing) based on a series of timers. The code worked fine however when I used the identicle code for the v1210 (setting up a single trend screen for recording) my start->trend SD Status message reads 256 which I assume is "failed to open file". Does anybody have any pointers on getting the trends to record to the SD card for a v1210? I would export the subroutine and attach it to this post but it won't let me export due to "elements that refernce Named Constants" Quote Link to comment Share on other sites More sharing options...
