93 IP Addresses Section 5-1 5-1-3 EtherNet/IP Unit IP Address Settings An IP address must be set e ven f or the EtherNet/IP Unit or b uilt-in Ether Net/IP por t bef ore Ether net commun ications can proceed. Use one o f the f ollowing methods to se t the IP addre ss of the EtherNet /IP Unit or b uilt-in EtherNet/IP por t.
94 IP Addresses in FINS Communications Section 5-2 5-1-5 CIDR CIDR, or classless interdomain ro uting, is used to assign IP addr esses that do not use classe s. IP addresses tha t use classes are sep arated int o bl ocks according to net IDs and host IDs, resu lting in inefficient usage o f IP address space.
95 IP Addresses in FINS Communications Section 5-2 • Ethernet address: A fixed n umb er is assigned to each EtherNet /IP Unit or b uilt-in EtherNet/I P por t and it cannot be changed.

98 IP Addresses in FINS Communications Section 5-2 Example Combined Metho d The combined method combines the IP address tab le method and the auto- matic gener ation method (dynamic). First the IP addr ess table is re f erenced. Then, if the applicab le FINS node address is f ound, the corresponding IP address is read.
99 IP Addresses in FINS Communications Section 5-2 Example Note When an internal tabl e IP address has bee n changed with the r eception of a FINS command, this is sent to the IP addr ess in the internal table .
