5.2 Electrical installation
5.2.1 Wiring according to EMC guidelines
In typical systems, standard shielding is sufficient for Ethernet cables.
However, in environments with a very high level of interference, EMC resistance can be improved
by additionally earthing the cable shield on both sides.
For this observe the following notes:
1. Remove the plastic sheath of the cable at a length of 2 cm.
2. Fasten the cable shield to the shield support of the standard device.
5.2.2 Network topology
It is typical of EtherNet/IP to have a rather free topology the limiting factor of which is large
message latencies due to e.g. switches connected in series.
Internal switch latency
( 21)
The combination of a line and a stub is useful for system wiring.
EtherNet/IP supports the following topologies:
•Line
[5-4] Line topology (S = scanner, A = adapter)
•Switch / star
[5-5] Switch / star topology (SW = switch, A = adapter)
