Note: The RBST pin detects the presence of a subsequent node on the ring. In the

 

absence of this detection (or if the node has no out connector at all), the network

 

ring is closed.

INTERBUS

 

 

The drop cable from the fieldbus to the Advantys STB INTERBUS NIM (and the one

Networking

from the NIM to the next INTERBUS node) must have connectors that observe this

Cable and

pin assignment scheme. INTERBUS networking cables are shielded, twisted-pair

Connectors

electrical cables, compliant with INTERBUS standard DR-303-1. There should not

 

be an interruption to any wire in bus cables. This allows for a future specification for

 

use of reserved pins.
