Generating and transferring a boot project
The CPU processes the user program stored in the main memory.
As the working memory is not backed up, the program will be lost
in the event of a power failure. You can therefore create a boot
project to store the program retentively.
You can generate the boot project in online mode or via the menu
of the controller. The boot program is generated with the current
operating system of the controller!
In online mode, the following steps are required:
X From the “Online menu”, select “Login”.
X If the controller is in the RUN state, you will be requested to
stop it.
X Select the “Create boot” project command.
