Abstract
The model-driven approach to software development has been increasingly applied to manage the growing complexity in modern manufacturing systems. With this approach, a model of a system is first created at a high-level of abstraction. The model is then converted into an executable program by means of automatic code generation tools. Models can be simulated and visualized throughout the entire design flow of the system, thereby increasing confidence of the design's correctness and its adherence to user requirements. Moreover, since the design is specified at a higher level of abstraction, the description itself is easier to understand, and consequently, less prone to errors. However, automated code generation from high-level models have typically been inefficient compared to hand-crafted code. In this paper, we demonstrate an approach for generating efficient code for systems modelled using IEC 61499 function blocks. We have also developed a tool chain that allows complex material handling systems to be modelled, visualized, and synthesized in a seamless fashion. Experimental evaluations show that our approach produces significantly faster and smaller code compared to an existing tool.
