Features of CC-Link
CC-Link can transmit bit data and word data at high speed with cyclic transmission, and the transmission time is stable as well
(guarantee for regularity). The cyclic transmission time (link scan time) is not affected by irregular message transmission (transient
transmission) to the HMI products. It is therefore possible to achieve highly stable control.
■Standard link scan time
(At transmission speed 10 Mbps, cyclic
transmission)
4 ms/64 stations (modules)

●By setting a local station as a standby master station, the data link
can be continued even if an error occurs in the master station.
●Stations disconnected from the data link due to errors are automatically returned
to the data link once they return to normal.
●Station is isolated due to error, although
data link is continued in the system.
●It is possible to check the data link status
using special relays and registers.
●Hardware and line connections can be
tested via offline tests.
●It is possible to test the line connection
and start/stop the data link from peripheral
devices via online tests.
