5 Editors in CoDeSys

5.1This is for all Editors...

Components of an Editor

All editors for POUs (Program Organization Units) consist of a declaration part and a body. The body can consist of other a text or a graphic editor; the declaration portion is always a text editor. Body and declaration part are separated by a screen divider that can be dragged, as required, by clicking it with the mouse and moving it up or down.

Print margins

The vertical and horizontal margins that apply when the editor contents are printed, are shown by red dashed lines if the 'Show print range' option in the project options in the dialog 'Workspace' was selected. The properties of the printer that was entered apply, as well as the size of the print layout selected in the 'File' 'Printer Setup' menu. If no printer setup or no print layout is entered, a default configuration is used (Default.DFR and default printer). The horizontal margins are drawn as if the options 'New page for each object' or 'New page for each sub-object' were selected in 'Documentation settings'. The lowest margin is not displayed.

Note: An exact display of the print margins is only possible when a zoom factor of 100% is selected.

Comment

User comments must be enclosed in the special symbol sequences „(*" and „*)". Example: (*This is a comment.*)

Comments are allowed in all text editors, at any location desired, that is in all declarations, the IL and ST languages and in self-defined data types. If the Project is printed out using a template, the comment that was entered during variable declaration appears in text-based program components after each variable.

In the FBD and LD graphic editors, comments can be entered for each network. To do this, search for the network on which you wish to comment and activate 'Insert' 'Comment'. In the Ladder Editor additionally a comment for each particular contact and coil can be added, if the corresponding options are activated in the menu 'Extras' 'Options'. In CFC there are special comment POUs which can be placed at will.

In SFC, you can enter comments about a step in the dialog for editing step attributes.

Nested comments are also allowed if the appropriate option in the 'Project' 'Options' 'Build Options' dialog is activated.

In Online mode, if you rest the mouse cursor for a short time on a variable, the type and if applicable the address and comment of that variable are displayed in a tooltip.

Zoom to POU

Shortcut: <Alt>+<Enter>

With this command a selected POU is loaded into its editor. The command is available in the context menu (<F2>) or in the 'Extras' menu, if the cursor is positioned on the name of a POU in a text editor or if the POU box is selected in a graphic editor.

If you are dealing with a POU from a library, then the library manager is called up, and the corresponding POU is displayed.

Open instance

This command corresponds to the 'Project' 'Open instance' command.
