12. System Configurations When Mak-
ing Bus Connections
In addition to bus connections, the following are also possible: MELSECNET connections, calcu-
lator link module connections, and direct connection to a CPU. The bus connection offers the
fastest PC CPU response speed.
With bus connections, expansion connectors are used to connect the main base and the expan-
sion base to the GOT. If a large-sized PC CPU is connected, the GOT can be installed up to 36.6
m (120 feet) from the main base. With a smaller PC CPU, the GOT can be installed as far as 30 m
(98 feet) from the main base.
In addition, up to three GOT modules can be connected to a single PC CPU. (There may be times
when only two GOT modules can be connected, depending on the type of PC CPU.)
