Editing in contact (ladder) language (softkeys).
18.5.1 Softkey "Analyze".
This softkey analyzes the program searching for errors. The errors found will be displayed
in the "Outputs" service window.
18.5.2 Softkey "File".
File "Save"
This softkey saves the file that is being edited.
File "Save as"
This softkey saves the file, that is being edited, with a different name. After saving the file,
one keeps editing the new file.
Softkey "Import file"
This softkey imports the translation of a program edited in mnemonic language into the
program that is now being edited. This softkey is useful for converting a mnemonic-language
file into a contact (ladder)-language file without having to compile the PLC project.
The following expressions in mnemonic language cannot be translated directly into contact
(ladder) language and the CNC will translate them as follows.
• Expressions with the XOR operator.
• Expressions where the NOT operator affects several contacts.
File "Export file"
This softkey exports to a file the translation into mnemonic language of the program that is
now being edited.
To close this window and return to the editor, press [ESC]. To return to the editor without
closing the window, press the [NEXT] key.
This softkey is used to restore, import or export a file. When selecting this option, the softkey
menu shows the available options. To return to the main menu, press the [BACK] key.
Original expression. Transformed expression.
a XOR b (a OR b) AND (NOT a OR NOT b)
NOT (a AND b) (NOT a OR NOT b)
