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.

 

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

 

transmitting data on the ring. The last device automatically closes and terminates

 

the network ring; sometimes this last device has no out connector.
