MSFS values

i am currently doing a home simulator...and was just wondering how am i actually able to see the increasing/decreasing values of for instance fs1n1...as i discovered the are logics such as "fs1n1 > 8" , "fsbattvolt < 17" and so on..how do we actually see that the fs1n1 and fsbattvolt goes to 8 and 17 respectively?

hope to get enlightened by the help of the people here ;)
