Recently, in the fields such as power, transportation and industry, it is strongly required to speed up improvement and rebuilding of systems in order to promote efficiency of business in the whole company that includes information and control systems. But already various heterogeneous middleware are installed in control systems and information systems. And they have static heterogeneity and dynamic heterogeneity. In this paper, we describe the technique of middleware cooperating by solving their heterogeneity for interconnecting and information sharing among heterogeneous systems from control systems to information systems. In addition we describe an example of applying our technique to a smart grid system.
