THE END: INTERBUS Club now part of Profibus User Organization

Ethernet has become THE major solution for future field busses – as has been suggested more than 20 years ago. It took many years before enough users requested Ethernet based field busses.

Interbus is one of successful conventional field busses – in strong competition with Profibus and other solutions. Finally, Ethernet wins over Interbus and many other standard field busses. The Interbus Club released this: “Within users a strong change by the field bus technologies in the direction of Ethernet is to be recognized. Hence, the INTERCBUS club had promptly decided to set on … ethernet based standard.”

There are (too) many Ethernet based international field bus standards specified in IEC 61158.

On the other side, IEC 61850 has – from the very beginning – decided to use native Ethernet and ICP/IP as specified in IEC 61850-8-1. There is an IEC 61850-8-1, where is the IEC 61850-8-2? The mapping of the ACSI and the information models to Profibus FMS was intended to be published as 8-2. Fortunately it was decided very some 15 years ago (!) to rely on Ethernet, TCP/IP and MMS – and not on a field bus.
