FL-net IP Address
To identify each communication device selected from among multiple devices connected to Ethernet, an IP address
(INET address) is used. Each device connected to Ethernet must be assigned a unique IP address.
The IP address is composed of the address of the network where the communication device is connected and the host
address of the communication device, and is classified into three network classes, A, B, and C (in addition to these
classes, network classes D and E are available for special purposes).
corresponds to the address parts, respectively.
In one network, the IP address of a communication device connected to the network is composed of the same network
address and a host address with a unique value.
The default value of an FL-net IP address is 192.168.250.N (N: 1 to 254).
It is recommended that the IP address is class C and its lower host address is identical to a node number in the FL-net
protocol.

FL-net Subnet Mask
The FL-net subnet mask is fixed at 255.255.255.0. The FL-net user need not set this subnet mask.
The classification of this value is the same as that of the original network address and host address parts of class C.
