The Comment function is used to enter a text explanation in the program. When you insert a
Comment instruction into the LD logic, it displays ????. After you key in a comment, the first few
words are displayed.
You can set the Comment mode option to Brief or Full.
Notes:
▪ Editing a comment makes the Programmer lose equality.
▪ Comment text is downloaded to the controller and retrieved upon Logic Upload.
