(c) The CPU module reads and writes intelligent function module data at fixed
intervals, using the following devices and setting.
X/Y (LX/LY) and B/W (LB/LW) devices that are set with common
parameters
Intelligent function module parameters (auto refresh setting) written to the
remote I/O module
The difference between this and (a) is that with the automatic refresh
settings for the intelligent function module parameters, the automatic
refresh destination of the intelligent function module is remote I/O module
data register D. Data register D, uses the PLC parameters for the remote
I/O module to transmit to link register W among devices.
· · · ·With this method, a sequence program can be created to allow
communication in the same way as with an intelligent function module
mounted to the same base units as the CPU module.
The analog input value for the analog-digital converter module, current
value for the high-speed count module and others are periodically
read to suit the digital-analog converter module analog output value
being periodically written.
In addition, there is no need to revise the intelligent function module
parameters even if the network parameters for the remote master
station are changed.

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) The remote I/O module uses transfer among devices for the PLC
parameters written to the host to send data register D to link register
W.
