For the limitations to the Host parameters’ setting, refer to 2-5-5 Parameter Settings for FINS/UDP at
Host Side.
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 number of networks and hosts that can be identified depends on the class used.
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 →130.58.17.32
Additional Information
• 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 network
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.
IP Address Allocation
The IP addresses are allocated so that they are unique for each node in the network (or between
two or more networks). If two or more nodes are allocated the same IP address, the remote nodes
with the same IP address will also malfunction.
IP (Internet Protocol) is a communications protocol that conforms to international standards.
Therefore, to connect to the Internet, always obtain IP addresses that have been allocated by a
public organization (i.e., the NIC in the country of use, such as the JPNIC in Japan). Using IP
addresses that are not recognized by the NIC (JPNIC) to connect to the Internet could have
unforeseen social consequences, such as causing the networks of another organizations to
malfunction unexpectedly.
