iFix: F_EGU: Parameter not configured (Typically a temporary condition)

When a graphic containing an analog value is called up, a message pops up frequently:

LI123/AI1/OUT.F_EGU: Parameter not configured. (Typically a temporary condition).

This message pops up when the graphic is not shown for a long time. The value to be shown is shown correctly.

How can I prevent this message to pop up?

(Version 10.3.1, 12.3.1).

  hi,
  does the LI123/AI1/OUT.F_EGU parameter actually exist in the control block?

  In reply to Niklas Flykt:

  The AI1/OUT parameter is linked to the OUT_SCALE parameter. When showing the parameter using the scale parameters, the message appears.
  I guess the F_EGU field is the numeric engineering units field.

  In reply to Maarten van der Waal:

  The Field EGU most likely isn't valid. If you want the engineering units, you will need to use AI1/OUT_SCALE.F_UNITS for the numberic or AI1/OUT_SCALE.A_UNITS for the text.
  I would really think about the Pros/Cons of this but you can add [_NOT_CONFIG_OK_] to the end of any datalink and this will disable the error message if it has a problem.

  When I "Select All" in Operate Configure for a graphic, and do a search for the field *F_EGU* nothing is found at all!
  In Datalinks, I use the F_UNITS and A_UNITS.
  For Fill Animations for tanks I use the option "Fetch Input Range on Open", which is the suspected item to generate the popup.

  As I remember there is a KBA on guardian about this issue. (Have to check.) The workaround EPM offers is to go to the rectangle animation and remove the 'fetch input range on open' checkbox, save & close the picture. Then open the picture again and check the checkbox again. I've also had the same issue on many level bar indicators and workaround did fix it.

  EDIT: Refer to KBA AK-1300-0050 for 2 other workarounds.

  Robert, great answer!
  So the suspect seems to be guilty!
  I will use the workaround and see whether the popup will not show again.
