Summary
Note
serial connection and creating the I/O tables), manually set the computer's IP
address in the Windows Local Area Connection Properties (example:
192.168.250.55). An online connection can be established just by setting the
Ethernet Unit's IP address (192.168.250.xx) and node in the CX-Programmer.
With the pre-Ver. 2.0 CPU Units, it was possible to communicate through 3
network levels max. (see note), including the local network. It was not possible
to communicate through 4 or more levels.
Note A Gateway to the network via serial communications was not counted as a
level.
Level count = 1
Network 1
With the CPU Unit Ver. 2.0 and later CS/CJ-series CPU Units, it is possible to
communicate through 8 network levels max. (see note), including the local
network.
1. FINS commands can only be sent across up to 8 network levels when the
destination is a CPU Unit. FINS commands can be sent to other destina-
tions up to 3 network levels away.
2. This functionality is enabled only after setting routing tables with the CX-
Net in CX-Programmer version 4.0 or higher.
3. A Gateway to the network via serial communications was not counted as a
level.
Compatible Networks
Only the following 2 kinds of networks can be used when communicating
through a maximum of 8 networks. The network levels can be combined in
any order.
• Controller Link
• Ethernet
Note Communications are restricted to a maximum of 3 networks through
DeviceNet and SYSMAC Link networks.
Configuration of Compatible Models
All of the CPU Units must be CPU Unit Ver. 2.0 and later CS/CJ-series CPU
Units. Also, the Gateway Counter Setting must be made with the CX-Net.
