Electrical wiring
The EtherNet/IP communication card provides standard RJ45 ports and supports the linear, star, and
ring topologies. The following three figures show the electrical wiring diagrams.
Use CAT5, CAT5e, and CAT6 network cables for electrical wiring. When the communication distance
is greater than 50 meters, use high-quality network cables that meet the high-quality standards.
