Hello:

I'm trying to adress to an array from an Script. I would like to do with and index (i), but even if I try directly WinCC tells me it is not possible. Any solution??

Massage "SmartTags: Invalid use of an array element" is displayed

If I take tag directly => Invalid use of an array element

Id I do as you tell me=> dont understand tag

I've tried and it is the same.

Also, it is and array comming from a Type (UDT - structure), I think this is the problem. When variable is declared as and Array, no problem. If array is inside an Structure (Type of data) => Problem!!

 You could send a picture of how you created the tag in the "HMI tags"?

There are not exactly HMI Tags. They are interface variables in a Faceplate.

For and string array this is working OK

PosX=SmartTags("PartChecks31_Partchecks{2}.PosX")

but not when it is a declared type with an array inside

I show you declaration (import) in Project Library and declaration in FacePlate interface

I think I've tried all possilities. And no way. I think problem is, this is not working when data array is in a structure. When it is a simple data it is working ok.

This is OK, in example.

SmartTags("Properties\Process.Screw.ScrewDriver1.Used")

This is Not OK

SmartTags("Properties\Texts.txtPartChecks[1]")

Both are inserted with "ctrl"+J and from Properties in Faceplate. I've tried [1], {1}, (1). In statement, out statement... nothing

 SmartTags("Properties\Texts.txtPartChecks.txtPartChecks[1]") .... Is this working ?

 tries to make a call by phone, in support of Siemens in their region.

I recently had the same problem, had to run through a list of passwords. Didn't work with an array.

Made al separate tags

PW1, PW2, PW3,.. of type Wstring (if you do a copy paste, TIA will autoindex the tagnames, so defining the tags should go fast :) )

edit: The ID tags in the script below are also created like the PW tags

then code in the script:

Do While (ID <> LookupID) And (i < 31)
    LookupID = SmartTags("ID" & CStr(i))
    i = i + 1
Loop

The string you pass with the smarttags command, doesn't have to be fixed, as long as your code produces a valid tagname, it works.

to be sure of execution, add als the 'On error resume next' at the beginning of your code and catch the error where you want to (if err.Number <> 0 then ... )
