This paper proposes a new Petri-nets description method for factory automation system software development. As factory automation systems are becoming larger and more complex, sometimes we encounter difficulties ; for instance, inadequate expression methods, and not yet established analyzing techniques for control mechanism. For the flexibility and expandability of the factory automation system software, programming paradigms modeled by network, such as Petri-net, are useful. As shown in the previous researches, the description capability of Petri-net is high ; nevertheless, sometimes the network model becomes complicated lacking comprehension. The complicated system specifications can be broke down by analyzing them from several different standpoints. That is to say, the control logic and hardware configurations are defined from each respective standpoint, and then the total system is reconstructed by integrating the planes. In this paper, we propose the conversion algorithm from the specified data to a Petri-net. The validity of the method was confirmed through an experimental application example.
