That is a good information i appreciate the effort.
this in case of min and max (lbs)
what if i want to convert volt to pound
so when i press on the scale it measure in volts over my analog input card.
will SCLP instruction help as well?
I think you may misunderstand how the Analog module works in a PLC system. It basically converts your analog signal (0-10V) to numbers via a Analog to Digital Converter. In your case those numbers are 0 to 31206. The PLC Processor uses those numbers only. It doesn't know what voltage is at the input, just the numbers that the input voltage represents.
The SCLP or Scale with Parameters is just a add on instruction for Ladder Programming or you can use SCP in Function Block Programming. In either case the instruction takes the A to D values (0 to 31206) and scales them to a "real world" value which in your case is 5 to 100 lbs. You can then use the "real world" numbers in your PLC program to do what ever you need.
