Mitsubishi COT1000 Information

New Functions and New Products
1. Introduction
Aiming at a "true" display at factory automation
(FA) workstations, the GT15 model of the GOT1000
series (hereafter, "GOT") and the GT11 standard model
were released in July 2004 with enhanced functions for
stand-alone use, to provide a rapid response,
high-definition display, enhanced troubleshooting,
greater work efficiency such as reduced downtime, high
value-added equipment, and lower total cost. The GT16
model, which is the successor to the GT15, was re-
leased in August 2008 to meet the user demand for
easy-to-understand solutions using moving images for
large-volume data processing, troubleshooting and
downtime reduction, and for network I/F standard fea-
tures. As a lower-cost medium-size model, the GT14
was released in July 2011 featuring improved display
performance and added functionality for data acquisi-
tion (logging), to raise the position of the medium-sized
model to compete with new products and improved
functions introduced by competitors.
Here, we introduce the new functions of the GOT
and the development of the recently-launched me-
dium-sized display GT14 model, in order to meet user
demands such as for uniform management of informa-
tion shared between personal computers connected to
a network.
2. Functional Enhancement of GOT1000
Series
2.1 GOT Solutions
When a failure occurs in production equipment,
rapid detection of the cause and measures to prevent
recurrence are essential for reducing downtime. Thus,
there is a high demand for various troubleshooting
functions on the display for monitoring and viewing the
condition of manufacturing equipment. Table 1 shows
the main GOT functions as indicators for efficiency and
visualization.
With regard to the GOT incorporated in manufac-
turing equipment, many functions have already been
developed not only to improve the equipment operation
and status check, but also to ensure a quick response
to failures on site by identifying the location and cause
of the failure, and to confirm the measures to be taken.

As troubleshooting solutions, GOT has a ladder
monitor function that searches for the circuit causing
equipment failure in order to change the value of the faulty
device; a remote operation function for operating a remote
personal computer on which an operator is checking the
manual; and an operation log function for saving historical
data on operations performed on the GOT, to help identify
and analyze the cause of faults. These functions facilitate
troubleshooting at production sites.
The following functions can be used as produc-
tion/management joint solutions with the GOT: an MES
interface function for promptly transmitting the device
values of connected equipment directly to an MES
database to save and manage the data; and an FTP
server function that allows a computer at an office to
read and write information files collected by the GOT
and files with the production control data such as mix-
ing conditions and processing conditions of materials.
In recent years, demand has increased for remote
monitoring and maintenance of overseas factories, in
particular, for viewing and operating GOT screens at
production sites. In response, we have provided a
SoftGOT-GOT link function as a joint solution for on-site
monitoring. With this function, it is possible to display
and operate the same screen as that of the on-site
GOT using SoftGOT on a personal computer with a
network connection to the GOT. The SoftGOT-GOT link
function enables monitoring of manufacturing equip-
ment by collecting screen data from the target GOT and
using it as the screen data for the SoftGOT to display
