Rockwell Automation 57C650 AutoMax Programming Executive Version 3.8 - Manual (Page 91)

5Ć35 Using the System Configurator
The prompts displayed on the screen will depend on your system
configuration and the options you choose as you progress through
the Load Operating System procedure.
Note: If you are loading an operating system to a Processor or UDC
that already contains one, you will be required to enter the rack
password before the operating system can be loaded. Loading the
operating system to an AutoMax Processor or UDC module that
already has one will cause all application tasks in the rack or the
UDC module to be stopped and deleted.
