Hi,

I'm working in TIA V14SP1 with WinCC Advanced V14 SP1, and have an UDT tag, and use it in a faceplate. This works fine for the basic stuff, i.e. pressing a button, changing background color etc.

But for example I have a UDT called "AnalogTag" with some data, i.e. value : REAL; description : string;Unit : string;

In a DB I have the following tags:

PT350[34.7; 'pressure tank 1'; bar]

TT351[21.8; 'temperature tank 1'; degr. C ]

I want to make a faceplate for this, showing the tagname, the value and the description.

I'm fine with the value, but how to deal with the tagname, the description and the Unit.

I prefer a simple a possible solution, scripting is fine, but I think there should be a solution out of the box.

You can define a faceplate and use textlist for the describition. With a value you can choose the right text and Show it in a symbolic I/O field.

At the properties of the I/O field you can define the unit. So you don't ueed the unit in your UDT.

As Interface property you can define a tag with the UDT data type, with can you bind through the objects.

A short introduction and a getting started for faceplates you can find under following link:

Hi,

I already had a look in https://support.industry.siemens.com/cs/attachments/68014632/68014632_Faceplates_EngineeringExamples_en.pdf

Ok, now my question more explained in detail:

Looking at section 4.2 (page 63) Example 1 picture, i would like to do the following: Instead of showning Fan 12, Fan 11, Fan 22, I would like to shown the real UDT tagname here.

So imagine I would have a UDT for the fan, called udtFan, and in a DB I have the following 3 tags of datatype udtFan.

XV131 : udtFan

XV167: udtFan

XV192: udtFan

I don't want to copy the values 131, 167, 192 into my UDT and use it from there on the HMI, but I want to show directly the tagname (XV131) on the screen. How can I access the tagname from the DB into WinCC.

Hey mh001,

the datatypes must to be the same.

With best regards
