This section explains the CC-Link/LT master function built in the FX
9.1.1

Outline of System

The CC-Link/LT is an open network offered to conserve wiring inside panels and equipment.
1. The CC-Link/LT achieves high-speed refresh at 0.3ms for up to 256 points including I/O
points in the PLC main unit.
(When 8 modules are connected in 16-point mode at a transmission rate of 2.5 Mbps)
2. Dedicated connectors can reduce man-hours for wiring. (CC-Link/LT dedicated flat cables,
VCTF cables and high flexible cables are available.)
3. Link devices within CC-Link/LT are assigned to X/Y devices in the PLC, therefore, sequence
programs can be prepared without recognizing the network.
(When remote device stations are used, they are accessed through the buffer memory.)
4. The power supply for the networks is built in.
Remote I/O stations can be connected without power supply adapters or dedicated power supplies.
The trunk length and drop length vary depending on the transmission speed.
