I have TIA Portal V13 SP1 Update 5 and when copying blocks between projects all network/block names and comments diasappears.

Is there any update regarding this issue?

Please see attached picture.

Split from TIA Portal V13 SP1 - Copying Blocks does not copy comments.

The problem is that the language setting of the source project that you copied from is different to the language setting of the destination project you are coping to.

The answer is to copy the blocks then go to the "Languages & Resources", open the "Project languages" and tick the languages of both projects.

Then open the "Projects Texts".  Copy the text in the column from the source project language to the text column of the destination project language.
