The GOT is equipped with backlights that use a liquid crystal display and are designed
so
that they
can
be replaced by the user. (A replacement backlight is available as an
option.) In addition, the GOT is configured of a main display module, a power supply
module, and a communications module which connect to the PC CPU. This modular
configuration makes maintenance much easier when required by
any o f the
modules.

Accommodating diverse connection configurations such as bus connections and
MELSECNET connections
In addition to bus connections which enable high-speed communications, the following are
also possible. This provides the user with unlimited flexibility in system configuration.
The connection interface required depends on the configuration being used.
Bus connection MELSECNET connection CPU direct connection
Calculator link connection (RS-422 communication) MELSEC-FX series connection
Omron R C connection Microcomputer connection

Bus connections (requires the A7GT-BUS/A7GT-BUS2/A7GT-BUSS, A7GT-BUS2S
I/F
module)
This configuration offers the fastest PC CPU response speed. If a large-sized PC CPU is
connected, the GOT can be installed up to 36.6 m (1 20 feet) from the main base. With a
smaller PC CPU, the GOT can be installed as far as 30m (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.)
