[3] IP addresses on an Ethernet

In general, the UDP/IP uses a 32-bit logical address called the "IP address."

The IP address consists of a network address and a host address. Normally, a class C configuration is used in the FA industry.

IP address classifications on an Ethernet

Each 8 bits of the address are separated by a period and can be expressed as a decimal number. For example, class C IP addresses are expressed as follows.

11000000

00000010

00000000

00000011

Note: The default address in the FL-net address scheme is 192.168.250.N (N: Node numbers 1 to 254).
