integer to floats

PLC SLC5/04

i am doing some limit comparisons based on ranges coming from an analog input card. Thing is the analog input card will have a raw count value from 0-32767, and im scaling that to 0-10.

My limit comparasions however are decimal values like limit ranges between 5.5 & 10, 4.5 and 1.2 etc.

So what i did was use a MOV instruction to move the raw I register into a Float register ex. F8:0, then use that F8:0 to do my comparisons.

Would this be the correct way to convert signed integers to floating points basically decimals???

Change Output scale 0-10000 then divide by 1000, this way you can handle 3 decimals.

You can use the "SCP" instruction to scale your raw data 0-32767 to 0.0 to 10.0 with a floating point data type as the destination of your "SCP" instruction instead of an integer.
