ML 1400 error code 0020

[sharkyh2o]

I got my fault finally using an overflow trap. It is the s;5/0 bit. Going to write a few more traps after each math instruction to find out if it is in the scaling or in my add subtracts. Kicking myself for not making all the traps initially like OkiePC suggested.
my scp is set up as followed. Input f8:0
input Min 0.0
Input Max 100.0
Scaled Min 0.0
Scaled Max 4020.0
Output o;0.5
Also from my Hmi . Scale to Integer
Data From 0.000
Data To 100.000
Display From 0
Display To 155
Again thanks for all the help. This is my first program using analog. Having a lot of fun. I'm going to get this.

Geospark, I used Two comparisons If O;0.5 was=<0 Then allow a subtraction of .175 to f8;0 and If O;0.5 was =>4000 Then allow an addition of .175 to f8;0
F8:0 being my scp input and O;0.5 scp output. I changed the zero value 1000 becuse i only need this function in run mode. Didn't want to change too much, i want to pinpoint my fault condition.
