IP address setting
To use the Ethernet port(s), set the IP address with CW Configurator.

 [IP Address]
The default value is set to the IP address for the C Controller module before shipment and after initialization.
Ethernet port
Ethernet port (CH1)
Ethernet port (CH2)
■Checking method of IP address
The IP address set to a C Controller module can be checked with the operation selection mode or the diagnostic function of
CW Configurator.
For details on the operation selection mode, refer to the following section.

Precautions
■Considerations for IP address setting
The following shows the considerations for setting IP address.
• Set the same value for the network portion of the IP addresses for the target device to be connected and the Ethernet port.
• Set the different value for the network portion of CH1 and CH2 on the Ethernet port.
• A message to the target device (including response packets such as ping) is sent (responded) from the Ethernet port that
has IP address of which network portion is the same.
• Do not set the IP address for a C Controller module with a user program.
■Considerations for Ethernet device connection
The following shows the considerations for connecting Ethernet devices.
• When the C Controller module has been replaced and also IP address has been changed, then reset the Ethernet device
too. If the Ethernet device holds the Ethernet address (MAC address) of the communication target, continuous
communication may not be performed since the module replacement will change the Ethernet address (MAC address).
• Perform the troubleshooting in accordance with the manual for the Ethernet device when an error occurred on the Ethernet
device.
• When Telnet or Shell of CW Workbench is connected to a C Controller module, an event/error message may be displayed
once VxWorks detects a network error. For details on the displayed event/message, refer to the manual for VxWorks.
Please ask Wind River Systems, Inc. for any event/message which cannot be handled.
■Considerations for 1000BASE-T/100BASE-TX connection
In a high-speed data communication (1000 Mbps/100 Mbps) via 1000BASE-T/100BASE-TX connection, a communication
error may occur due to the effect of high frequency noise generated from the equipment other than C Controller system,
depending on the installation environment. Take the following countermeasures on a C Controller module to eliminate the
effect of high frequency noise when constructing a network system.
• Do not install the twisted pair cables together with the main circuit or power lines, or bring them close to each other.
• Make sure to place the twisted pair cable in a duct.
• In the environment where the cable is susceptible to noise, use a shielded twisted pair cable (STP cable).
• In an environment where the system is susceptible to noise, include a retry processing in a user program.
• Change the target device connected with the C Controller module to one which communicates at 10 Mbps, and decrease
the data transmission rate.
