This section explains how to use a PLC to control the LK-DN100 configured for the
DeviceNet network.
This section describes only those functions and settings of the DeviceNet master unit necessary for
communicating with the LK-DN100. Refer to the manual supplied with the DeviceNet master unit and
PLC for details on functions and settings of each device.
Operation and memory configuration with DeviceNet
On the DeviceNet network, the LK-DN100 operates as a slave to the DeviceNet master
unit connected via the network cable.
• The buffer memory inside the LK-DN100 is linked to link memory in the DeviceNet
master unit according to the memory configuration illustrated below.
• Set and program (3-15) according to this memory configuration.
