Codesys 3.5, comments on array elements

[leon78]

Can you please tell me if it is possible to add comments to array elements in Codesys 3.5?
For example, Control Expert (Schneider Electric)

Li Leon:
It does not seem to be possible to add comments straightforwardly for arrays. A Google search showed two forums with unanswered posts on your very same question.
The workaround below requires the creation of a user data type, in which you can create an array of strings to store your comments in the initialization of the array within the user data type declaration. I know this is ugly, but I can't think of anything else.

Hi Alfredo,
Thanks, but I can't use your idea. It demand to use a lot of variables' memory for the comments.

Yes, I though this might be a problem

Another option is a STRUCT. (left hand side of image)

If you want to be able to do array access like for loops, you can use a UNION as well. (right hand side of image)


In both cases, they use the same controller memory of 6 bytes, as can be seen in the memory view (bottom of image).
