Thanks Hooey,
The conversion to real was helpful.
Getting roughly the same result. I'm running the simulator, here are the values I am using.
In = 1000
InMin = 100
InMax = 20000
SclMin = 1
SclMax = 100
SclOut = -49597.80.
My trusty excel sheet yields 5.48
This is only my second Omron project so I am still green on this. I attached the .cxp with the FB. Am I using the correct registers? Cheers.
