Basic Settings
Section 2-9
Default Setting
The Ethernet Unit operates using the default IP address when the Unit is
mounted to the PLC and initially registered in the I/O tables (i.e., when the
Unit settings have not been made and the IP Address Display/Setting in the
CPU Bus Unit Words Allocated in the DM Area is still all zeros).
The default IP address is determined as follows:
Default IP address = 192.168.250.FINS node address
The FINS node address is set by the rotary switch on the front of the Ethernet
Unit. If the defaults are used for the IP address and the Unit settings, the set-
tings will be as shown below.
Setting the IP Address in the CPU Bus Unit Words Allocated in the DM
Area
This method sets the IP address in the IP Address Display/Setting Area in the
CPU Bus Unit Words Allocated in the DM Area, when the IP address is not set
in the Unit Setup. When the IP address is set in the Unit Setup, the IP Address
Display/Setting Area becomes the area for displaying the settings.
To make settings in the IP Address Display/Setting Area, use the CX-Pro-
grammer or Programming Console to write the values. In order for the new
settings to go into effect, either the Ethernet Unit must be restarted or the
power must be turned ON again to the PLC.
IP address: (1)(2).(3)(4).(5)(6).(7)(8) (hexadecimal)
If only the IP address is set, according to the IP Address Display/Setting Area,
and the defaults are used for all other Unit settings, the settings will be as
shown below.
Unit Setup
This method sets the IP address by first selecting the Ethernet Unit from the
CX-Programmer's I/O Table Window while connected online, and then setting
the IP address from the Unit Setup.
