This section explains how to use a PLC to control the LK-CC100 configured for a CC-Link
network.
This section describes only those functions and settings of the CC-Link master station necessary for
communicating with the LK-CC100. Refer to the manual supplied with the CC-Link master station and
PLC for details on functions and settings of each device.
Operation and memory configuration with CC-Link
On a CC-Link network, the LK-CC100 operates as a slave station (remote device station)
to the CC-Link master station connected via the network cable.
• The buffer memory inside the LK-CC100 is linked to remote I/O and remote registers on
the CC-Link master station according to the memory configuration illustrated below.
• Control the system by setting and programming (2-14) according to this memory
configuration.
