Cyber-physical systems (CPS) have shaped the discussion about Industry 4.0 (I4.0) for some time. To ensure the competitiveness of manufacturing enterprises the vision for the future figures out cyber-physical production systems (CPPS) as a core component of a modern factory. Adaptability and coping with complexity are (among others) potentials of this new generation of production management. The successful transformation of this theoretical construct into practical implementation can only take place with regard to the conditions characterizing the context of a factory. The subject of this contribution is a concept that takes up the brownfield character and describes a solution for extending existing (legacy) systems with CPS capabilities.

网络物理系统（CPS）形成了一段时间的有关工业4.0（I4.0）的讨论。为了确保制造企业的竞争力，对未来的愿景将网络物理生产系统（CPPS）视为现代化工厂的核心组成部分。适应性和应对复杂性（尤其是）是新一代生产管理的潜力。这种理论构造成功地转化为实际实施，只能在表征工厂环境的条件下进行。该贡献的主题是一个概念，该概念占据了棕地特征，并描述了用于扩展具有CPS功能的现有（旧式）系统的解决方案。
