When Using Gx Works3, Gx Works2, Gx Developer - Mitsubishi Electric GT1685 Connection Manual


When connecting the GOT multi-drop
connection
FA transparent function is available for each GOT in the
GOT multi-drop connection system.
(1) Standard monitor OS installation, Communication
driver writing
When using FA transparent function in GOT multi-drop
connection, the writing of the standard monitor OS and
communication driver to the GOT from GT Designer3
(Version 1.18U or later), as well as the writing of the
standard monitor OS and communication driver to the
serial multi-drop connection unit are required.
(2) Number of personal computers
Only one personal computer can be connected to the
multi-drop connection system.
Only one personal computer
(3) Monitor speed of GOT
The monitoring performance slows down according to
the number of monitoring GOTs. While using FA
transparent function, the monitoring performance of the
whole multi-drop system decreases. As a result,
timeout error may occur in GOTs in the system.

When connecting the GOT and personal
computer with modem connection
When using the FA transparent function with a modem,
the communication settings of compatible software,
modem connection tool, modem and GOT must be set
correctly to communicate with the GOT. If not correctly
set, the communication cannot be performed.

When connecting the GOT and personal
computer with serial or USB
When the operations shown below are executed, the
operation is executed in the PLC. However, the display
on the GOT may stop temporarily or the display of
