18.3 Program editing
To edit a program, select it from the "Programs" service list and select the "Edit" option of
the softkey menu. The PLC will show the right editor for the language of the selected program;
a text editor if the program is in mnemonic language or C language or a contact (ladder) editor
if the program is edited in contact (ladder) language.
Editor description
The text editor window (top image) and that of the contact (ladder) editor (bottom image)
show the following information.
A Title bar.
Name of the program selected for editing. An "*" next to the program name means that
the changes made to the program have not been saved (the program must be saved so
they do not get lost).
B Edit area.
Line number and area for editing the program. A program edited in contact (ladder)
language will contain numbered blocks representing the various elements.
C Status bar.
In a program edited in C language or mnemonic language, the bar shows information
about the cursor position and the status of the editor options.
In a program edited in contact (ladder) language, the bar shows the comments of a
contact and other messages.
CAP Capital letters. When active, the text is always written in capital letters.
OVR Overwrite text. It toggles between overwriting and inserting text. When active, it
overwrites the existing text.
