5 - Editors in CoDeSys
5.3.2 The Editor for Structured Text...
This is how a POU written in ST appears under the corresponding CoDeSys editor:
All editors for POUs consist of a declaration part and a body. These are separated by a screen
divider.
The editor for Structured Text is a text editor with the usual capabilities of Windows text editors. The
most important commands are found in the context menu (right mouse button or +).
For information about the language, see Chapter 2.2.2, 'Structured Text (ST).
5.4 The Graphic Editors...
Zoom
The editors of the graphically oriented languages, sequential function chart SFC, ladder diagram LD
and function block diagram FBD and of free graphic function block diagrams have many points in
common. In the following paragraphs these features will be summarized; the specific descriptions of
LD, FBD an CFC, as well as the Sequential Function Chart language SFC follow in separate sections.
The implementation in the graphics editors is supported by syntax coloring.
Objects such as POUs, actions, transitions etc. in the languages SFC, LD, FBD, CFC and in
visualizations can be enlarged or reduced in size with a zoom function. All elements of the window
contents of the implementation part are affected; the declaration part remains unchanged.
In standard form, every object is displayed with the zoom level 100%. The zoom level that is set is
saved as an object property in the project.
The printing of project documentation always occurs at the 100% display level!
The zoom level can be set through a selection list in the toolbar. Values between 25% and 400% can
be selected; individual values between 10% and 500% can be entered manually.
The selection of a zoom level is only available if the cursor rests on an object created in a graphical
language or a visualization object.
