Cables

The following INTERBUS remote bus cables should be used:
Parameter
Cable construction
Conductor cross-
section
Operating capacity
Impedance
Use only screened cables constructed as twisted pairs. The best possible EMC
interference immunity can only be achieved by using screened cables.
5.4.7 Cable lengths
Depending on the type of cable used and the magnitude of the external
interference, the distance between two devices can be up to 400 meters. The total
expansion of an INTERBUS system can be up to 12.8 kilometers. The number of
devices connected to the bus is limited to 512.
5.4.8 INTERBUS ring termination
A characteristic of the INTERBUS system is its physical ring structure. Each
connected device lies in the bus between two other stations. If this is not the case,
for example, at the end of a branch with a bus terminal, then the ring line must be
closed.
The ring line on the IDENTControl is automatically closed. If the network of the
remote bus is extended at the outgoing socket using a suitable cable, the ring line
is opened automatically for the following devices.
