NJ-series CPU Unit Built-in EtherNet/IP Port User’s Manual (W506)
Connect the CPU Unit and the computer that runs the Sysmac Studio via USB or Ethernet, and then
perform the following procedure.
1
Select Controller
−
Communications Setup and click the OK Button in the Sysmac Studio
Project Window.
Additional Information
• If there is an error in the set IP address, the NJ-series CPU Unit behaves as follows:
• The NET RUN indicator on the CPU Unit does not light and the NET ERR indicator flashes
red.
• A TCP/IP Basic Settings Error is recorded in the event log.
If you use a USB direct connection or an Ethernet direction connection, it is possible to reset the
IP address because the Sysmac Studio can connect to the CPU Unit via the built-in EtherNet/IP
port.
Precautions for Correct UsePrecautions for Correct Use
• If the IP address is duplicated or not set correctly, communications are not possible via the
EtherNet/IP network.
• The IP address range shown below is used by the system and cannot be specified.
169.254.0.0 to 169.254.255.255
192.168.255.0 to 192.168.255.255
The connection configuration that is set (USB or EtherNet/IP) is saved in the project. (The file is
xxx.txs.) If you open a saved project on the Sysmac Studio, you can connect to the EtherNet/IP network
without redoing the settings.
