DM Area Allocations
IP Address Display/Setting Area
Note
Application
Simple operation (i.e., The CPU
Unit Bus System Setup is used at
its default settings. Only the IP
address is set.)
Operation with the CPU Unit Bus
System Setup set as desired (i.e.,
The default settings are not used.)
Replacing the previous CS1W-
ETN01/CS1W-ETN11 and using
the previous settings.

If the local IP address in the CPU Bus Unit System Setup is set to a value
other than 0.0.0.0, this area (words m+98 and m+99) will act as an IP Address
Display Area and the local IP address set in the CPU Bus Unit System Setup
will be read and stored here when the power is turned ON or the Unit
restarted. If the local IP address in the CPU Bus Unit System Setup is set to
0.0.0.0 (the default setting), this value is read by the Ethernet Unit when the
power is turned ON or the Unit restarted and is used as the local IP address.
Choose the method used to set the local IP address as follows:
Set the local IP address in the CPU Bus Unit System Setup when making
other settings in the CPU Bus Unit System Setup. The settings are made with
CX-Programmer.
Set the local IP address in the allocated words in the DM Area when using the
CPU Bus Unit System Setup at its default settings (i.e., for simple operation).
The setting is usually made with a Programming Console.

(1) If a value other than 00.00.00.00 is set as the local IP address in the CPU
Bus Unit System Setup, even if an IP address is set in the allocated words
in the DM Area, it will be overwritten with the setting in the CPU Bus Unit
System Setup.
(2) It is not possible to set the following IP addresses. If any of these values
are set, the ERH indicator will flash.
• IP addresses where all network number bits are 0 or 1.
• IP addresses where all host number bits are 0 or 1.
• IP addresses where all subnet number bits are 1.
• IP addresses that start with 127 (7F hexadecimal, e.g., 127.35.21.16).

Setting area
The setting in the allocated words in
the DM Area is enabled only when the
IP address in the CPU Unit Bus Sys-
tem Setup is set to 0.0.0.0.
If the IP address in the CPU Unit Bus
System Setup is set to a value other
than 00.00.00.00, this value is stored in
the allocated words in the DM Area.
The IP address set in the CPU Unit Bus
System Setup is stored in the allocated
words in the DM Area.
The IP address is set using a rotary
switch in the previous CS1W-ETN01/
CS1W-ETN11 Ethernet Units. In the
new Ethernet Units, the IP address set
with the rotary switch is displayed in the
DM Area. This area is backed up by the
battery, so the IP address can be used
without resetting.
