Today the development of software in plant industry is a step by step strategy along the life cycle with different notations and different tools. The requirement analysis and the basic engineering can be described and structured with project management software just using natural language. The design of software is done function oriented, procedure/ imperative, and component based with IEC 61131-3 development environments and implemented on different targets. This design offers various benefits for characteristic assignments of process automation. But it does not support the development along the whole life cycle of a system. Process control engineers need to discuss the functionality of a plant in an early phase of a project. A “language” which is based on the requirements of the process itself is necessary to communicate between different skilled engineers,. The quality of the notation is strongly depending on an appropriate modeling concept for the process characteristics. This paper will derive a draft of an object oriented approach for this domain. The basement is made with a detailed requirement analysis for distributed systems in process automation including the specification of distributed systems with a special focus on user requirements.      «
