z EtherNet/IP and Ethernet
Tag data links and FINS network communications are enabled over Ethernet cable. In addition, by
executing FTP commands for the PLC from the host computer connected to the Ethernet, the con-
tents of the files on the Memory Card installed in the CPU Unit can be read or written. Data can be
sent and received using UDP and TCP protocols. These functions enable a greater compatibility
with host information networks.
Tag Data Links
Data links can be executed between two PLCs for high-speed, large-capacity data transfers with
user-set refresh periods for each area.
FINS Network Communications
Connecting to the built-in EtherNet/IP port or to a CPU Unit connected to an EtherNet/IP Unit or
Ethernet Unit enables FINS message communications with other PLCs or between the PLC and a
host computer on the Ethernet network.
z Controller Link
The Controller Link Network is a special network for OMRON PLC FA. Connecting a Controller Link
Unit to the network enables data links between PLCs, so that data can be shared without program-
ming, and FINS message communications between PLCs, which enable separate control and data
transfer when required. The Controller Link Network connections use either twisted-pair cables or
optical fiber cables. Data links and message communications are also possible between the PLC
and personal computer. Data links enable large-capacity and free allocations. FINS message com-
munications also allow large-capacity data transfer.
