2.1.3 PC56 Architecture
The continuing advances in processor technology have influenced the PC56
architecture. The speed at which new processors are introduced helped
determine that a sub-module approach be used in the design of the PC56. The
PC56 module consists of a two board stack, the ControlLogix
®
board and the
CPU board.
The ControlLogix ® board contains the components necessary to communicate
with the 1756 backplane as well as all the physical interfaces on the front of the
module. The PC56 interfaces with the ControlLogix
®
backplane through a shared
memory window and uses a PCI interrupt. The memory window and interrupt are
allocated by the system BIOS during the boot process.
The CPU board houses the processor, the PCI chipset and connector and the
Ethernet chipset. These components are most likely to change with new
advances in component technology.
