I am having the same problem.
The integer values to a digital panel meter works fine, but the floating point value looks random.
The problem is a floating point is a 2 word value.
Those words can also be different byte order ( AB CD, BA DC, CD AB ).
In other hmis, I have defined it with FP ######, or define the byte order little endian/ big endian.
Not shure what to use for AdvancedHMI.

Try putting an L in front of the address:

L420480

Tried this, but still had issues.

Archie, Thanks for this amazing HMI! It's great to see a good quality usable HMI that doesn't cost your first born child. I came across your software while looking for an HMI to use in an automated bar I am building. I am programming a SLC503 to control the drink dispensing and I am attempting to use your HMI to facilitate the drink selections.
