Master station and remote stations
At 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
At 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,
communications at each station are performed in the same manner as unicast mode. ( Page 29 At unicast mode)
No.0, No.1, No.2: Station No.0 (master station), station No.1, station No.2
No.1, No.2: Send range: to station No.1, send range: to station No.2
No.1, No.2: Send range: from station No.1, send range: from station No.2
Class A: CC-Link IE TSN Class A device
Class B: CC-Link IE TSN Class B device
 The device of the FX5 CPU module turns on.
 The status data of the device of the FX5 CPU module is stored in the link devices (RY, RWw) of the master station by link refresh.
 The status data 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 data of the link devices (RY, RWw) of the remote station is output to the external device.
 The status data of the external device is stored in the link devices (RX, RWr) of the remote station.
 The status data 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 data of the link devices (RX, RWr) of the master station is stored in the devices of the FX5 CPU module by link refresh.
