FA TRANSPARENT
FUNCTION
• Reading/Writing files of ladder edit
When PLC write is failed while using the FA
transparent function
The execution of PLC write using the FA transparent
function may be failed due to some reason such as
cable disconnection.
When this occurs, re-execute the PLC write from the
same personal computer, or reset the PLC CPU.
Restrictions on GX Developer during backup/
restore execution
(1) When reading/writing data from/to a PLC, monitoring a
PLC, and others are executed with GX Developer or
GX Works2 with the FA transparent function during the
backup/restore execution with the GOT, the backup/
restore is stopped.
Check that reading/writing data from/to the PLC,
monitoring the PLC, and others are not executed with
GX Developer or GX Works2 with the FA transparent
function. Execute the backup/restore with the GOT
again.
(2) When the backup/restore is executed with the GOT
while reading/writing data from/to a PLC, monitoring a
PLC, and others are executed with GX Developer or
GX Works2 with the FA transparent function, errors
occur on GX Developer or GX Works2.
The backup/restore with the GOT is correctly executed.
When connecting the GOT and personal
computer with modem connection
(1) Timeout time settings
When the FA transparent function is used with a
modem, it takes time for the initial communication with
PLC and GX Works2 or GX Developer and a timeout
may occur. In that case, set a longer time for the initial
communication timeout time for the GOT modem
connection tool.
(2) Communication settings
When the FA transparent function is used via modem,
the communication setting differs depending on the
connection target of the GOT.
Set as follows.
*1 Communication settings of GX Works2/GX Developer are
set automatically, and setting is not required.
When connecting the ACPU and motion
controller CPU (A series) in bus connection
Do not execute write during RUN with GX Developer.
An error may occur in the PLC due to the write during
RUN, what may stop the PLC.
22.7.3 When using MT Developer,
MT Works2
When exiting MT Developer, MT Works2
For 45 seconds after GX Developer, MT Works2 has
been exited, the GOT continues monitoring at the same
speed as when the FA transparent function is working.
When PLC write is failed while using the FA
transparent function
The execution of PLC write using the FA transparent
function may be failed due to some reasons such as
cable disconnection.
When this occurs, re-execute the PLC write from the
same personal computer, or reset the motion controller
CPU.
When a cable disconnection has occurred
When the cable between the GOT and the motion CPU
is disconnected, it takes time until a timeout error
occurs in MT Developer.
