1.1 CC-Link IE Field Network
(2) 1Gbps communication speed
1Gbps communication speed allows high-speed communication. Also, the takt time can be reduced due to the
improved performance of communication response.
(3) Use of Ethernet cable
A 1000BASE-T-compliant Ethernet is used for the connection interface. The wiring cost can be reduced because
1000BASE-T-compliant Ethernet cables are commercially available. ( Page 56, Section 5.2)
(4) Flexible wiring for system arrangements
The network can be wired into star topology, line topology, and ring topology. ( Page 47, Section 5.1.1)
For star topology, a 1000BASE-T compliant switching hub can be used. ( Page 57, Section 5.2.2)
Wiring is highly flexible because a network can consist of a combination of star and line topologies. For example,
the control panels can be connected through a star topology and the production lines through a line topology.
