Bad Value - Conversion Error Error Number: 570621953 (22030001)

Getting this error on a single module running a PID loop. The loops input is normal but the OUT parameter displays as "nan"

All the settings for the PID block are correct but still getting this weird output.\

This message pops up when opening the faceplate in Operate:

  The parameter in the message is PID1/OUT.CV as a percentage of OUT_SCALE. nan presumably stands for "not a number".
  
  I suggest you check that OUT_SCALE is set to something numeric and sensible as it looks as though the calculation of the percentage is producing a non-numeric value.
