Special notes for using a CC-Link system
Take note of the following when using the LK-CC100 in a CC-Link network.
• The LK-CC100 is a network controller for CC-Link Ver. 2.00 or Ver. 1.10. If using the LK-
CC100 on a CC-Link Ver. 2.00 network, it must be connected to a master device
compatible with CC-Link Ver. 2.00. The LK-CC100 operates as a Ver. 1.10 unit when the
extended cyclic setting is set to single. It operates as a Ver. 2.00 unit at double or faster.
• CC-Link supports up to 64 connected devices. The actual number of devices that can
be connected is limited by the number of stations each unit occupies. Refer to the
manual for the master device used on the CC-Link to determine the number of stations
occupied and the maximum number of devices that can be connected.
• The maximum total length of the entire CC-Link network is 1.2 km (at 156 kbps). Refer to
the following table for the relation between communication speed and maximum cable
length.
• Connect the LK-CC100 using the dedicated CC-Link cable (Ver. 1.10 or higher).
• Always connect a terminator (110 ohms 1/2W) between DA - DB on the units at both
ends of the CC-Link.
• The setup support software LK-Navigator 2 (LK-H2) cannot be used to display received
light waveforms through the CC-Link.
Precautions on CC-Link settings
• The parameters for the LK-CC100 should be set to match the CC-Link master unit. Set
using the STATION No. setting switch, B RATE setting switch, and MODE setting switch.
• Refer to the manual for the CC-Link master unit for details on how to set it.
The number of stations occupied must be set according to the data read/write size.
