AUTO REFRESH FUNCTION
7.2
Auto Refresh Setting of CC-Link
Auto refresh of the CC-Link designates automatic communications between the QnACPU
and the buffer memory for cyclic communication of CC-Link master stations/local stations.
Data for communication varies depending on the remote station connected.
• Remote I/O station (Communication in ON/OFF data)
• Remote device station (Communication in ON/OFF data and Word data)
• Intelligent device station (Communication in ON/OFF data and Word data)
• Master station/local station (Communication in ON/OFF data and Word data)
The auto refresh setting of the CC-Link allows communication with other stations of CC-
Link using the FROM/TO instruction without communicating with the master station of the
CC-Link.
