Routing tables
Define communications paths for FINS messages. Routing tables are
set from the CX-Programmer.
IP Address Configuration
The IP address is comprised of 32 bits of binary data, consisting of the net ID and host ID.
The net ID is the address that identifies the network, and the host ID is the ID that identifies
the host (node).
The IP address is divided into class A, B, and C. Select the address system from among the
classes according to the network configuration.

The IP address is a 32-bit value divided into four 8-bit fields. Each octet is expressed as a
decimal and is separated by a period.
Example: 10000010 00111010 00010001 00100000

Reference
•
Set the same net ID for all nodes in the same network.
•
The net ID of the IP address is the value that identifies the Ethernet network (IP net-
work segment). The net ID is not the same as the network address used for FINS
communications.
•
The
IP network segment is the logical network unit that is configured by the nodes
that have the same net ID.
