5.2.1
EMC-compliant wiring
In typical systems, standard shielding of the Ethernet cables is sufficient.
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 on a length of 2 cm.
2. Fasten the cable shield onto the shield contact of the standard device.
5.2.2
Network topology
The bus system must be designed as a ring. Feed and return lines must be integrated in the
same bus cable. The ring goes from the INTERBUS master via all other nodes and back again
to the master.
An INTERBUS ring can consist of maximally 513 nodes (1 master + standard devices
connected).
