Guest Gary Dakin Posted February 23, 2012 Report Share Posted February 23, 2012 I'm experimenting with trends. I'm trying to create a trend of a temperature (AI1) assigned to MI1. Just for learning purposes when I create the trend I give it a History Samples Value of 100. How does the software know where to store the 100 values.

MVP 2023 Joe Tauser Posted February 27, 2012 MVP 2023 Report Share Posted February 27, 2012 The PLC allocates memory based on what the user has defined in the application, and Trends are their own animal (not to be confused with user accessible memory such as MBs and MIs). You can't look at the actual Trend data, it's only accessible by the Trend object. In Visilogic, go to Build->Projected Memory Map to see what I'm talking about. You can also save Trend data to an SD card, but to view it you have to load it back. Joe T. Link to comment Share on other sites More sharing options...
