Overview
MELSK: GOT
Improved maintenance access and resistance to

I
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
of
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 RC 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.)
