About INTERBUS

Introduction

INTERBUS implements a master/slave network model. It can communicate with up

to 512 nodes over a distance of 12.8 km, and can read 1024 inputs and write 1024

outputs in 4 ms. Despite exceptional configuration flexibility, system performance

and the reliability of I/O data have not been compromised.

Each network slave has an in connector for receiving data and an out connector for

transmitting data on the ring. The last device (sometimes having no out connector)

automatically closes and terminates the network ring.

Components of a simplified INTERBUS network are shown in the figure below:

INTERBUS Club is the supporting trade association that creates specifications for

INTERBUS networks and devices.
