Boot Image The transfer and installation of the controller software to the controller storage memory via
Ethernet or floppy disks is executed by a basic program named Boot Image.
This basic program must always be in the storage memory. At start-up of the controller, with-
out any controller software installed, Boot Image will start and ask the operator for controller
software installation instructions. If the controller software is already installed and a warm
start is performed, Boot Image is not used. The installed controller software can be deleted
by cold start and then the Boot Image will be reactivated.
