Reconfigurable function blocks: Extension to the standard IEC 61499

Abstract

This paper presents an extension to the IEC 61499 standard called Reconfigurable Function Block. The major goal is to optimize the design of a network of Function Blocks by encapsulating several reconfiguration scenarios in one function block. We define the events triggering the reconfiguration and we attach a probability to each event to express its uncertainty. In order to verify the system and to evaluate its performances, we model it with a class of Petri nets. The proposed approach is applied to a medical platform BROS as a case study throughout a developed software tool called ZiZo v3.
