Create Backup: »PLC Designer« creates a backup file at every save with the extension
".bak". Contrary to the *.asd-file (see below, 'Auto Save') this *.bak-file is kept after
closing the project. So you can restore the version you had before the last project save.
Auto Save: While you are working, your project is saved according to a defined time
interval (Auto Save Interval) to a temporary file with the extension ".asd" in the
projects directory. This file is erased at a normal exit from the program. If for any
reason »PLC Designer« is not shut down "normally" (e.g. due to a power failure), then
the file will not get erased. When you open the file again the following message
appears:
You can now decide whether you want to open the original file or the auto save
file.
If a library *.lib is opened as project, a corresponding auto-save-file "*.asl" will be
created.
Auto save before compile: The project will be saved before each compilation. In doing
so a file with the extension ".asd" resp. ".asl" will be created, which behaves like
described above for the option 'Auto Save'.
Ask for project info: When saving a new project or saving a project under a new
name, the project info is automatically called. You can visualize the project info with
the command 'Project' 'Project info' and also process it.
Auto Load: At the next start of »PLC Designer« the last open project is automatically
loaded. The loading of a project at the start of »PLC Designer« can also take place by
entering the project in the command line.
Remind of boot project on exit: If the project has been modified and downloaded
without creating a new boot project since the last download of a boot project, then a
dialog will advise the user before leaving the project: "No boot project created since
last download. Exit anyway ?".
