I am quite new at tags but have no issue creating basic tags. One thing that I struggle with is the MINRAW and MAXRAW values.
From what I was taught if the MAX is 20000 and the MIN is 4000 then the conversion should be 16000 and you set the DZero=4000. I honestly have no idea what those numbers mean but I know that when it is set this way no one yells at me.
so where I have trouble is with the negative numbers. Today they want me to create new tags with values like this. MAX 300 MIN -300 or MAX 1000 and MIN -100. Can someone explain to me the proper way to calculate this? if I do a calculator and try 1000 minus -100 it does not seem to compute. What should be the correct way to compute these negative numbers?
