How to read data from HMI Field IO

Hello friends,

Im trying to get data (it can be string, int, whatever he puts there)  that the user  write on a field io by Script in VB Script Wincc TIA Portal v13.

The problem is I dont know how to create a reference to the data, wrote on the field, from the Script. When I get it, i'll be save it on a txt file, but this part is already made.

I dont know about VB Script but on C we have the function getText f.e:

myTag = FieldIO.GetText(); // I dont know how to do that on VB.

Thanks you very much!

Let me ask you a question,

why you need a script and do not just use a tag??

That's a great question, let me answer you.

I created a tag WString, as internal tag of Wincc, and reference it with my field io. But when i try to save the characters that i put int the field io, i culdn't do it. That's means the program didnt save anything. That way im trying now with a script.

Maybe, probably, i made something wrong and cause that didnt work and you can clarify my mind about how to do it.

Thank you for your answer!

Martín.

What means "Try to save"?

Can you upload your program?

  see if it helps you.

This solution is well if you do NOT know name of tag but name of field....

I do not tested if it works.

Works.

Dim  test

test = HmiRuntime.Screens("00_ScreenName_000").ScreenItems("teste1").ProcessValue

SmartTags("msg_status") = CInt(test)
