20. FA TRANSPARENT FUNCTION
20.7 Precautions
(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 the personal
computer by 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.
20.7.2 When using GX Woks2

When [monitor conditions] have been set on
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 Works2 to
cancel the setting.(An error may be output when the
monitor conditions setting is cancelled.)
(5) When the time check of 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 Works2 to 30 seconds or
less.

When exiting GX Works2
For 45 seconds after GX Works2 has been exited, the
GOT continues monitoring at the same speed as when
the FA transparent function is working.
