Can anybody help me how sets real input from PLC(i.e: %MW12-real) into Vijeo Designer, I already tried with the following procedure but the reading in HMI have differ with PLC reading.
 
use in your program WORD_TO_REAL
the input is a word with a minimum and a maximum depending on the input
so first make it real (float) and then scale it to engineering units.
have a look at www.oscat.de for subroutines
and at www.3s-software.com for a forum about codesys.
