3.5 CPU
section
This unit contains the system’s intelligent core and is fully contained inside an extractable
metal box which ensures the EM shielding, making maintenance easier (refer to Fig. 2.1,
p.9). It can be divided into the following parts:
Interface Bus Backplane;
CPU Board;
Interface Board;
Ethernet board.
The CPU Board, the Ethernet board and the Interface Board are plugged into the
Interface Bus Backplane (ISA bus) as shown in Fig. 3.1, p.19. Additional custom
interface boards, such as CAN bus, can be inserted by qualified personnel into the bus
for further communication facilities.
