• To meet the flexibility demands introduced by modern markets, process plants have to become more flexible themselves. To tackle this issue and to ease vertical integration of IT-systems in enterprises a service-oriented approach is promising. Despite the developments concerning service-oriented architectures there is no standardized interface for service systems in process control systems. Therefore, in this paper we lay a basis for service systems in process control. We propose a message format and a way to describe services. We show which actions of a service interaction sequence have to be done in the engineering phase and which can be done at runtime. This is needed to meet non-functional requirements of control applications. The overall aim of the service system is to enhance flexibility without creating new dependencies.
