FA TRANSPARENT FUNCTION
(2) When the FA transparent function is used in a bus
connection
When the FA transparent function is used in a bus
connection, the following GX Works2 functions cannot
be executed.
The message [The executed function is not supported.
Please check the manual and other documentation.] is
displayed on GX Works2.
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
(PX Developer, etc.), and it takes a few minutes to
recover the monitoring between the PLC and the GOT.
When the FA transparent function is used in
an Ethernet connection
(1) GX Works2 function
When the FA transparent function is used in an
Ethernet connection, the following GX Works2
functions cannot be executed.
The message [The executed function is not supported.
Please check the manual and other documentation.] is
displayed on GX Works2.
(2) GOT station monitoring function
When the FA transparent function is used in an
Ethernet connection, GOT station monitoring function
cannot be operated.
Therefore, in the cases of [no connection target], [PLC
power OFF], etc., the monitoring of the GOT delays for
the timeout time.
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.
