“Create backup files”

: Each time the project is saved, CODESYS also saves the project as the file ‎<project name>.project‎ in addition to the file ‎<project name>.backup‎. You can rename the backup file and open it in the programming system.

“Automatically save every … minutes”

: CODESYS automatically saves the project at the specified time intervals in a file ‎<project name>.autosave‎, which you can reload following non-regular closing of the programming system.

CODESYS deletes the ‎.autosave‎ file whenever the project is closed or saved regularly. CODESYS retains the ‎.autosave‎ file in the case of an irregular termination. When you open a project for which there is an associated autosave file, the “Auto Save Backup” dialog opens. In this dialog you select whether the ‎.autosave‎ file or the version of the project last saved by the user should be opened.

“Save before build”

CODESYS saves the project automatically before each build operation.

“Create project recovery information”

Requirement: The “No protection” option is selected in the project settings in the “Security” category. This means that the project is not protected against unauthorized access and data manipulation, and there is no integrity check when the project is loaded.

: If a project crashes during editing, then the next time the project is opened, a prompt is displayed asking whether or not you want to restore the unsaved data and create a new project file. If you click “Yes”, then another dialog opens. In this dialog, you can select whether you want to open the restored project or open the project comparison. This project comparison displays the differences between the last saved project and the restored project.

Note: The project restore records every change on the hard disk when the change is made. If a power failure or hard disk error occurs on the hard disk during this operation, then the last change may be lost.

“Advanced Settings”

The “Advanced Settings” dialog opens.

“At startup”
