Numeric input shows ????

[HAT1234 0]

Trying to debug HMI software for Panel View Plus 6 using ME studio 8.10. I have around 10 numeric input boxes on the same HMI page. Some of the numeric input boxes show ???? in runtime.

Other numeric inputs on the same HMI page show the correct value. All data is being read by the PLC from all numeric input boxes.

Any ideas what could be wrong?

If a numeric input HMI box has ????, the address of the HMI tag is not mapped to an address in the PLC and thusly its value is undefined.  I believe this can also happen for data that is out of range (i.e., range = 0-9 but value = 10)
