Hi Bullmeister.

I kown it sound strange, but you need the taglogging tags to store the values and show in function control. Here a discripton, that you can see howyour datadisplayed in function trend control.

1. create 2 tags (x-value, y-value) in the tag management
2. open taglogging and create a prozessvalue-archive with standard configuration
3. add 2 archive tags (x-arch, y-arch) to the prozessvalue-archive, which store the tags (x-value, y-value)
4. change the value in the column "Acquisition Type" to "upon change" by both tags
5. open a wincc-picture in the Graphicsdesigner
6. add 2 IO-fields at the pictureand connect them to the tags (x-value, y-value), label it with static texts.
7. add a control (smart object > Control) and choose in the opening dialog "WinCC function trend control"
8. Open the properties of the control (doubleclick on it) and click at the register "Data Connection" and enter the archive tags (x-arch, y-arch) by "Tag name X" and "Tag name Y", use the buttons right of the io-field.
9. close the dialog and start the runtime

Now you can enter in both io-fields some values and you can seehow it will displayed. That was the easy part.
TheNext step is, to read in your files.and set the tags after you read a couple value (x-value, y-value).

Your txt-files has 5 row and 4 columns and i did not get whichrow+columnrepresents which value.

I try to find a good methode to read out the files, because i need this too, my files a structured in the same way. If you have any soulution, please post it
