The cyclic transmission function periodically exchanges data between the remote
master station and remote I/O station using link device (LX/LY/LB/LW)
The following explains the differences between when the module connected to the
remote I/O station is an input/output module and when it is an intelligent module
connected to it.

(1) Communicating with input/output module

The remote master station uses input/output X/Y(LX/LY) device after the actual
I/O for the host so that there can be communication with the input/output module
on the remote I/O station
When communicating between the remote master station and the remote I/O
station, network data is written to the remote master station.
The device range for communicating with each remote I/O station is set by the
remote master station common parameters.
PLC parameters written to the remote I/O station will not cause problems with the
input/output module communication, even with the default settings. Change the
settings of the PLC parameters as needed.
