FA TRANSPARENT
FUNCTION
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.
(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
timeout may appear on GX Works2.
*1 The remote operations only of when the connection type
between the GOT and CPU is the direct CPU connection or
computer link connection are applied.
22.7.2 When using GX Developer,
GX Woks2
When connecting to QCPU (A mode)
When connecting to QCPU (A mode), set the PLC type
to "A4UCPU" or "QCPU (A mode)" on GX Developer.
When connecting the GOT and PC with RS-
232
The [Transmission speed] setting in [PC side I/F Serial
setting] in GX Developer or GX Works2 must be within
the range supported by the connected CPU.
When [monitor conditions] have been set on
GX Developer, GX Works2
(1) Monitoring performance of the GOT is temporarily
suspended.
(2) The GOT cannot respond to the touch switch operation
and numerical/ascii inputs.
(3) Writing to PLC results in a system alarm occurrence
and displays the message, "315 Device writing error.
Correct device.".
(4) While setting the monitor conditions, do not perform
any operation which makes the GOT restart (e.g.
downloading project data, changing utility data).
Doing so may display a system alarm, "402
Communication timeout. Confirm communication
pathway or modules." when the GOT restarts.
When the monitor conditions setting for the PLC CPU
has not been cancelled, reconnect GX Developer, GX
Works2 to cancel the setting.(An error may be output
when the monitor conditions setting is cancelled.)
(5) When the time check of GX Developer, GX Works2 is
set to 30 seconds or more in the monitor condition
settings, the message "402 Communication timeout.
Confirm communication pathway or modules." may
appear.
Set the time check time of GX Developer, GX Works2
to 30 seconds or less.
When exiting GX Developer, GX Works2
For 45 seconds after GX Developer, GX Works2 has
been exited, the GOT continues monitoring at the same
speed as when the FA transparent function is working.
