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.
Example: Using the CX-Programmer to Set the IP Address to 10.3.65.1
When an IP address is set in the Unit Setup, that value is displayed in the IP
Address Display/Setting Area in the DM Area words allocated for CPU Bus
Units.
When the IP address is set by the CX-Programmer, and the defaults are used
for all other Unit settings, the settings will be as shown below.

■ Subnet Mask
For the subnet mask, all bits corresponding to the bits in the IP address used
as either the net number or the subnet number are set to 1, and the bits corre-
sponding to the host number are set to 0. These settings must be made when
using an address conversion method other than the IP address table method.
Starting from unit version 1.5, it is possible to use classless inter-domain rout-
ing by enabling CIDR. Enabling CIDR enables setting 192.0.0.0 to
255.255.255.252 for the subnet mask regardless of the IP address class.
Status
Set by CX-Programmer.
Uses value corresponding to IP address class when
not using CIDR.
