Section 1-2
Note
When 4-conductor VCTF cable or Special Flat Cable is used to connect fewer
than 16 Slaves, the main line can be up to 100 m long and the total branch
line length can be up to 50 m in High-speed Communications Mode. (These
are the same conditions as when 2-conductor VCTF cable is used.)
• Refer to
for a list of compatible Slaves.
1-2-3
CPU Unit, Expansion Units, and Expansion I/O Units
A series of up to 3 Expansion I/O Units or Expansion Units can be connected
to the expansion I/O connector on the CPU Unit.
There are three types of Expansion Units available: Analog I/O Unit, Tempera-
ture Sensor Unit, and CompoBus/S I/O Link Unit.
A PC with 106 I/O points (the maximum) can be assembled by connecting
three 32-point Expansion I/O Units to a CPU Unit.
