In recent years, as supervisory and control systems software for steel plants is getting more and more complicated, it has been the most important issue to build the system low cost and efficiently. As the programming environment for plant systems, the graphical language such as the function block diagram is widely utilized. This kind of language contributes to the improvement of software productivity, while the view point of reuse is focused on programs. In order to aim at further improvement, it is required to promote the reuse from the view point of plant level design.<br>In this paper, we propose an engineering model such that reusable parts is build from the view point of plant level design of plant equipment and operation functions. We also introduce the engineering tool based on the model. An evaluation result of partial application of the tool for a real plant system shows that 70% of developed parts can be estimated to be reused in the future application and half of inter-connections among software parts can be automated.
