What am I doing wrong?

I have configured my module for PERCENT RANGE (0-10000) and have a tag connected to output 0. No matter what I set the tag to, it shows up at Local:2:O.Ch0Data but the 4-20mA stays at 4.0 mA.

I know it is something simple just can't figure out what.
 
Could you post your program for us? I don't know about everybody else, but my crystal ball is running a little foggy today ;)

There's a number of things it could be, from configuration, to the processor not being in RUN, to the program rung not scanning, to...
 
Yea - I know it could be about anything, but the processor is in Run and I am programming in function block and the routine is running. I'm reading my AI points right next to the logic for the Analog Output.

I just figured there was a gotcha that the old CompactLogix gurus had figured out long ago.
 
I finally figured it out - the Hi Clamp is set by default to 1. Since I wanted to use PCT RANGE I had to set it to 10000.
