Hi everybody

I have created several HMI faceplates which have two properties, both based on a PLC UDT with 7 fields of different types of data.  The values of those fields are used to show information on the graphic icon (see "Faceplate properties" image).  The difference between the faceplates is how the graphically information is displayed

With the release event of a push button included in each faceplate, an internal script is executed (only two lines), which copies the values of two fields of the first property to the same fields of the second one (see "Faceplate script" image).

The problem comes when I compile the HMI project, because I get for each instance of each faceplete the following WARNING: "The parameter of a function is not available for trigger <UDT name>, event 'Change value'.  The referenced object does not exist." (See "Compile warning").

The warning messages always refer to the first property, from where the values are copied.  The "Change value" events of any field of that property are not used. Neither of the second property (See "Change value event" image).

The functioning of all them in runtime is ok, as it was planned.

So, I don't understand the meaning of the warning and I would like to solve them, because is annoying and confusing to see all them after every compilation.

Can anybody help me?

Thanks in advance

Hi again

Sorry, I forgot to indicate the version of the WinCC TIA Portal.  It's 15.1.

There's no problem to open the ZIP file.
