(2) 1Gbps communication speed
1Gbps communication speed allows high-speed communication. Also, the cycle 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. (Refer to Section 5.2.)
1000BASE-T
(4) Flexible wiring for system arrangements
The network can be wired into star topology and line topology. (Refer to Section 5.1.1.)
For star topology, a 1000BASE-T compliant switching hub can be used. (Refer to
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.
