A modeling approach for verification of IEC1499 function blocks using net condition/event systems

This paper presents a preliminary report on verification of discrete control applications defined by a new international standard draft IEC 1499. As a first step to verification, the structures presented in the IEC1499 are modeled with Net Condition/Event Systems, for which there exist formal methods and tools of proofing various qualitative and quantitative properties. The paper illustrates the methodology of modeling and outlines further steps towards the full-scale verification of execution control of IEC1499 applications.
