I need to add a flowmeter to this program. It looks like all of the analog inputs have this very similar calculation. I'm trying to understand the math so I can put the correct values in for the range that I will be dealing with. The N44:8 is the value from the analog IFE card. F63:4 is called the "IO conversion factor". For this IO point it is 15.25. N49:14 has a value of 512. F62.4 is the actual flow rate resulting after the math. I get the F63:4 factor - that somehow scales the integer input to a 0 - max flowrate. I do not understand the purpose of the FRD N49:14 mostly. Something something BCD - can anyone give any insight? Thanks.
