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 LKCC100 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.

Communication speed Cable length between

stations

156 kbit/s 20 cm min. 1,200 m

625 kbit/s 900 m

2.5 M bit/s 400 m

5 M bit/s 160 m

10 M bit/s 100 m

• 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.

Maximum total cable length

Field network connection specifications

Master settings

To connect the LK-CC100 to the CC-Link master, it is necessary to configure the slave attribute and memory allocation settings.

 Slave attributes

Register the LK-CC100 to the CC-Link master unit as a remote device station. You can also set this by importing a CSP file into the software for the master unit (ladder programming software, CC-Link setting software).

 Memory allocation settings

In order to exchange data between the LK-CC100 and CC-Link master unit, the memory allocation must be set using the software for the master unit (ladder programming software, CC-Link setting software).

Reference

• The RX, RY, RWw, and RWr communicated over the CC-Link is stored in the master unit's buffer memory.

• When multiple slaves are being used, the memory is allocated automatically for each slave according to the specified starting address. You can view the memory allocation information for each slave in the CC-Link setting software.

• CSP files can be downloaded from the KEYENCE website. http://www.keyence.co.jp/
