1.1.2 Expansion of Backplane
FP2 backplane
Expansion cable
CPU backplane Expansion backplane
Only one backplane can be added-on for expansion.
Expansion is simply connecting a new backplane with a special expansion cable. Any
backplane other than a 5-module type can be used for expansion.
Notes
• A 5-module type backplane cannot be expanded.
• A 5-module type backplane cannot be added on for expansion.
• Only one backplane can be added-on for expansion.
• A power supply unit is also necessary on an expansion back-
plane.

A maximum of eight I/O units (including the unit built in the CPU)
can be controlled per backplane. Even if further I/O units are
installed, they are not recognized.
Note) When using the CPU unit with S−LINK, seven slots are free,
however, the units actually usable are only six. (Refer to Chapter 3
I/O Allocation.)
