Communications using RX, RY, RWr, and RWw
This allows data to be exchanged in units of bits and in units of words between the master station and slave station.
Master station and remote stations
■
Unicast mode
1:1 communications between the master station and each remote station. Remote stations do not communicate with each
other.
• Output from the master station
• Input from the remote station
■
Multicast mode
• The master station and remote station send data on the line in multicast mode in each send range.
• The master station receives all data, but the remote station discards the data of another remote station. Therefore,
communication at each station is performed in the same manner as unicast mode. (

Class A: CC-Link IE TSN Class A device
Class B: CC-Link IE TSN Class B device
The device of the CPU module turns on.
The device status of the CPU module is stored in the link devices (RY, RWw) of the master station by link refresh.
The status of the link devices (RY, RWw) of the master station is stored in the link devices (RY, RWw) of each remote station by cyclic data transfer
processing.
The status of the link devices (RY, RWw) of the remote station is output to the external device.
The status of the external device is stored in the link devices (RX, RWr) of the remote station.
The status of the link devices (RX, RWr) of the remote station is stored in the link devices (RX, RWr) of the master station by cyclic data transfer processing.
The status of the link devices (RX, RWr) of the master station is stored in the devices of the CPU module by link refresh.
