The Graphic Editors
If the minimal comment size is greater than 0, then in order to enter a comment you simply click in the
comment line and then enter the comment. Otherwise you first must select the network to which a
comment is to be entered, and use 'Insert' 'Comment' to insert a comment line. In contrast to the
program text, comments are displayed in grey.
Alternative Look & Feel: The following options allow to define an alternative look of the networks.
Comments per Contact (only for Ladder editor): If this option is activated, you can assign an
individual comment to each contact or coil. In the edit field Lines for Variable Comment enter the
number of lines which should be reserved and displayed for the comment. If this setting is done, a

contact resp. a coil that comment will be displayed which has been defined at the declaration of the
variable used for the contact or coil (see above, picture at 'Comments per Contact'). The comment
