CC-Link IE Field Network FUNCTION
This function communicates with data and devices on the network through the CC-Link IE Field Network.
6.1
Cyclic Transmission
This uses a link device (RX, RY, RWr, RWw), to periodically exchange data between stations on the same network.
Cyclic transmission applies to the data communication for which high-speed, high-frequency read-write is required.
Data flow and link device assignment
This section shows data flow and link device assignment.
If master station and slave station (with exception of local stations)
This can communicate 1:1 between master stations and slave stations.
The input status from slave station external devices is stored in the master station link device (RX, RWr), in the master station
link device status (RY, RWw) is output to the slave station external device.
The order of slave stations is the same as the one set in the network configuration settings. (
