FA TRANSPARENT FUNCTION
22.7 Precautions
22.7.1 Precautions common to each
software
 GOT interface required to use the FA
transparent function
Connect the personal computer, to which GX
Developer or any other relevant software has been
installed, to the RS-232 interface or USB interface of
the GOT.
When performing the FA transparent function, use
either RS-232 interface or USB interface of the GOT.
Using both of them to perform the FA transparent
function concurrently is not allowed.
 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
*1
• When the GOT is set up
*1
• 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
5. BUS CONNECTION
6. DIRECT CONNECTION TO CPU
7. COMPUTER LINK CONNECTION
 When monitoring the PLC CPU from a
personal computer
When monitoring the PLC CPU from a personal
computer, the GOT and personal computer refresh the
display slower.
 Software available for the FA transparent
function
When multiple kinds of software are activated on one
personal computer, 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.
 When the FA transparent function is used in
a bus connection
(1) When multiple GOTs are bus-connected
When multiple GOTs are bus-connected, the FA
transparent function can be used on each GOT.
However, note that the monitoring performance of each
GOT slows down as the number of monitoring GOTs
and personal computers increases.
