MVP 2023 Flex727 Posted November 15, 2017 MVP 2023 Report Share Posted November 15, 2017 Look in the Help file under Float to find the Float Convert function. That function is available in the ladder Math Menu. Quote Link to comment Share on other sites More sharing options...
hotwires Posted November 18, 2017 Report Share Posted November 18, 2017 I tried ladder snippet in photo on a V430 (online mode). Using an MI as "C" result only shows a "D#2", I had to use an ML to get 2300 (derived from -0.0023). If you need MI just drop a STORE block with A=ML202, B=MI202. This will give you a baseline MI that will go up or down proportionally to the MF. If you want to preserve the negative sign then omit the ABS function block. The middle FB is found in MATH, FLOAT, CONVERT, INV (A+B/n). Hope this helps! Quote Link to comment Share on other sites More sharing options...
