Hello, 

I have a faceplate, where I have defined an array of int in the Tag Interface.

Within the faceplate, I have an IO Field, in which I use a script to generate the Process value.

With the script, I want to return the value of an element of my array.

How can I do that dynamically? 

If I do :

return Tags("Array[1]").Read();

 It works. But if I do : 

return Tags("Array[" + n + "]").Read(); //where n is for example const n = 2;

Then it doesn't work.. 

Any idea to make it working? 

Hi!

Have you tried the code for "Access an array element" on page 26 of the following document:

-> SIMATIC WinCC Unified Tips and Tricks for Scripting (JavaScript)

Hope it helps!
