FF-SIS


ABB Corporate Research CenterResearch and Development within the area of automation

networks at Billingstad (Oslo, Norway) One important topic is Safe Communication

About 22 scientists in Oslo

Integrated part of Scandinavian Corporate Research Center

and Global Lab for Automation (ca 700 scientists)

Work together with different ABB business units on

research activities and front-end technology development

What do we need to ensure with safe communication?

Communication:

We must know that the values of the data we receiveis right

We must know that the data is not too old

We must know that the data is received from the rightnode to the right node

This is the purpose of the layered protocolssuch as TCP/IP or others?

Yes, but the probability calculations for errors is notgood enough

Increased diagnostic coverage with FF-SIS

The instruments and actuators

are included in the safety systemand becomes part of the

diagnostic testing

The increased diagnosticcoverage

Makes it possible to at an earlystage do repair in many cases

No longer proven in usecertification

TV will not accept the proven inuse concept for FF-SIS devices
