Abstract
Abstract An expanded register rack assembly is for a processor based device. The expanded register rack assembly has a first board register rack assembly having multiple slots for receiving multiple electronic modules including a programmable controller module. The expanded register rack also has a second register rack having multiple slots for receiving multiple electronic modules. The expanded register rack assembly further has a communicative coupling between the first and second board racks, the communicative coupling permitting the programmable controller module to selectively access any of the other electronic modules received in the first and second multiple slots without the need for communication hardware mounted in any of the slots.
