31.7 Precautions

31.7.1 Precautions common to each
software

GOT interface required to use the FA
transparent function
Connect the PC, to which GX Developer or any other
relevant software has been installed, to the USB
interface of the GOT.
When performing the FA transparent function, use the
USB interface of the GOT.
The FA transparent function cannot be used in other
communication interfaces.

Conditions for suspending the FA transparent
function
The FA transparent function is also suspended when
any of the following operations, which stop the GOT
monitor, is performed.
Note that the FA transparent function will not be
stopped while using the optional function such as the
Utility display or ladder monitor function.
• When project data is written/read, or when the OS is
written by GT Designer3
• When the GOT is set up
• When no communication request (online monitor,
etc.) has been issued from GX Developer for 45
minutes
*1 A timeout error occurs in GX Developer.

When GOT monitoring is faulty
The FA transparent function cannot be used in case
that the GOT monitoring is faulty due to PLC CPU
errors or faulty communication between the PLC CPU
and GOT.
When GOT monitoring is faulty, check the following.
(1) Whether the PLC CPU operates normally
Refer to the User's Manual of the PLC CPU you
use.
(2) Whether the PLC CPU and GOT are connected
normally
21. DIRECT CONNECTION TO CPU
22. COMPUTER LINK CONNECTION


When monitoring the PLC CPU from a PC
When monitoring the PLC CPU from a PC, the GOT
and PC refresh the display slower.

Software available for the FA tranparent
function
When multiple kinds of software are activated on one
PC, only one of them is available for communications
using the FA transparent function.
Do not concurrently perform any communications using
the FA transparent function.
(Offline operation with each software is available.)
Also, do not perform communications with the GOT
(e.g. downloading project data) from GT Designer3
during execution of communications using the FA
transparent function.
During online operation

When PLC power disconnection occurs with
the FA transparent function being used
While the FA transparent function is being used, if the
communication between the PLC and the GOT is
stopped due to PLC power disconnection or a
disconnection of the communication cable between the
PLC and the GOT, the GOT waits for timeout against
the communication request from the peripheral devices
(GX Developer, etc.), and it takes a few minutes to
recover the monitoring between the PLC and the GOT.
During online operation
GX Developer, etc.
