Blackbox testing methodology for SafetyLON according to the IEC 61508 Standard

The paper presents methodology applied for blackbox testing of SafetyLON components. Tests cover both hardware and software and are used to accomplish TUV certification of certain SafetyLON components. The test specification is also a step in delivering test-bed which can greatly simplify development and certification of final SafetyLON devices. Test cases and testing tools used for testing activities in SafetyLON project are also presented.
