Appendix A
Specifying the Ethernet -> CS/CJ ETN-DRM Unit I/F as the Connection Interface
The user can connect the computer (i.e., the Network Configurator) directly to an Ethernet network and con-
nect online to the DeviceNet network using a CS/CJ-series Ethernet Unit and CS/CJ-series DeviceNet Unit.
Note Connection via Ethernet is supported only when using both the CS/CJ-series Ethernet Unit and the CS/
CJ-series DeviceNet Unit. (This connection is not possible if Units from any other PLC Series are used.)
When multiple PLCs with both Ethernet Units and DeviceNet Units are connected to the Ethernet network, the
specified DeviceNet network can be connected to online by switching the connection destination. The destina-
tion DeviceNet network is registered by specifying the IP address of the Ethernet Unit and the unit number of
the DeviceNet Unit.
Note The registered name of the destination DeviceNet network can be specified to switch the destination
DeviceNet network. The name of the destination DeviceNet network can be registered by specifying the
following items.
• IP address and UDP port number of the Ethernet Unit
• Network address, node address, and CPU Bus Unit unit number of the DeviceNet Unit
• FINS node address of the computer (i.e., the Network Configurator)
