Absolute zero Modbus Experience

Hi
Start by using Read test and read a register you know what the value is like temperature. Play with different settings and once you get correct reading drop it here and I can help you start with the profile.

Hi

I've gotten what I believe are some correct read data. 
I did take notice; the list of registers is 1 number higher that the read test responds to (probably because the first register is actually no. 0 and not 1)
Then I began trying to make a profile with your UIO20 profile as a baseline.
Does it look like I'm doing it right? Is there anything I should be alerted about, when making the profile?

Thanks a lot
