Features

This section describes features of CC-Link/LT.
(1) Easy connection/disconnection of communication cable
By using dedicated connectors, communication cables can be connected/disconnected with one simple motion.
This allows modules to be easily extended, added, and changed.
Using dedicated flat cables, VCTF cables, and flexible cables leads to reduction in wiring work and cable cost.
(2) No parameter settings
Network parameters for operating a CC-Link/LT system need not to be set.
(3) Simplified programming
CC-Link/LT link devices are assigned for X/Y devices of the CPU module. This allows creating programs using
only X/Y devices without considering the network.
(4) Transmission speed auto-tracking function
Transmission speed setting is required for the master module only and is not required for remote stations.
(5) Slave station cutoff function
Even if a module goes down due to an error, communications among the other modules will continue.
Note if the cable on the trunk line is disconnected, data link among all stations will fail.
(6) Automatic return function
When a disconnected module recovers from an error, it automatically returns to the network and restarts data link.
