what exactly your question If you are using Slc/micrologix analog module use SCP instrustion to convert to engg units If you are using PLC analog module use this formula Scaled value = (input value x rate) + offset Rate = (scaled max. – scaled min.) / (input max. – input min.) Offset = scaled min. – (input min. x rate) it is something like Y=MX+C If you want more details http://www.plctalk.net/qanda/showthread.ph...highlight=scale
