CC-Link IE Field Network (FR-A800-GF)

5.21.1 Cyclic transmission

Data communication is available periodically among stations on the same network. Link devices (RX, RY, RWr, and RWw) are
used.
 Data flow and link device assignment (master and slave stations (except
for local stations))
One-to-one communication is possible between the master and slave stations.
The status information of the link devices (RY and RWw) of the master station is output to the external device of the slave
station, and the input status information from the external device of the slave station is stored in the link devices (RX and RWr)
of the master station.
