1.4.1 Single network system
A single network system is one system that connects the control station and the
normal stations with an optical fiber cable or a coaxial cable.
(1) Optical loop system
In the optical loop system, 1 control station and 63 normal stations (a total of 64
stations) can be connected. Any station number can be assigned as the control
station. However, only one station can be set as the control station per system.
In the following sample system, station number 1 has been assigned as the
control station.

(2) Coaxial bus system
In the coaxial bus system, 1 control station and 31 normal stations (a total of 32
stations) can be connected. As in the optical loop system, any station number can
be assigned as the control station. However, only one station can be set as the
control station per system.
