4) Link register W, follows the common parameters set in the remote
master station for communication between the remote master station
and the remote I/O station.
5) Link register W between the master module and QCPU are refreshed.
[Input/output]
6) X/Y(LX/LY) is the same as communication with I/O module.
(d) The CPU module reads or writes data register D of the remote I/O module
with a link dedicated instruction (READ/WRITE).
To data register D, intelligent function module data are refreshed, using
intelligent function parameters (auto refresh setting).
· · · ·This method can be used for the following applications.
• During intelligent function module control, when reading and writing
data with the sequence program only when data is needed.
• When link register W to remote I/O station is insufficient.
For details on the read/write instructions, refer to the Q corresponding
MELSECNET/H network system reference manual (PLC to PLC network).

1) GX Configurator is used to write the initial settings for the intelligent
function module and the automatic refresh settings to the remote I/O
station remote I/O module.
2) The remote I/O module follows the automatic refresh settings and
refreshes the data in the buffer memory of the intelligent function
module to the data register D of the remote I/O module.
3) QCPU uses the read/write instructions to read and write to remote I/O
module data register D.
