P1 PID output issue

The productivity pid appears to give 13107-65535 output regardless of the output module. I have the combo AD/DA module which is 13 bit. I had to rescale the output from the PID before I sent it to the module to 8193 max.

 

Before I figured this out the output just stayed stuck at 66635. Is the math conversion the only way to handle this?

    For the analog combo modules input is 13 bit and output is 12 bit resolution. I would check to see what do you have your Input Range Min/Max and our Output Range Min/Max values. These are used in calculating the scaling factor to apply to the Process Output after PID calculations.
