OR
Note The rightmost byte of the host number becomes the FINS node number, and
set the rest of the host number to all zeroes.
Example 1: Class B
Local IP address:
Subnet mask:
Remote FINS node number:
Remote IP address
Example 2: Class A
Local IP address:
Subnet mask:
Remote FINS node number:
Remote IP address
Note With CS-series Ethernet Units, when using either the address conversion
method (the default) or the combined method, set the local IP address
switches 7 and 8 on the back of the Ethernet Unit and the node number to the
same values, and set the other host settings to 0. If the values are wrong, the
ERC indicator will flash.
With CJ-series Units, when using either the address conversion method (the
default) or the combined method, set the rightmost byte of the local IP
address and the node number to the same values, and set the other host set-
tings to 0. If the values are wrong, the ERH indicator will flash.
Characteristics of Automatic Generation Method
The automatic address generation method has the advantage of clarifying the
correspondence between the FINS address and the IP address, but it also
has the following restrictions.
1. It cannot be applied outside of the range with the same network ID.
2. The remote host number must be within the range of FINS node numbers
(1 to 126).
3. The Ethernet Unit's host number and the node number must be set to the
same value.
The automatic address generation method is the default setting, so there is no
need to set it with the CX-Programmer if the setting has not been changed.
The IP address table method converts the FINS node number to an IP
address based on a preset correspondence table called an IP address table.
The IP address table is prepared in the System Setup, using the CX-Program-
mer. For details on the System Setup, refer to 4-2 CPU Bus Unit System
