Marco Brombacher Posted January 3, 2019 Report Share Posted January 3, 2019 I need to calculate the difference between the current tag value and its value during the previous scan. The tag value originates from a Formula using analogue data from a UIA-0402N Analog input and stores a Real value. Is there a easy way to do this without using a Data Table or other FB that uses the SD card memory? Quote Link to comment Share on other sites More sharing options...
