Rapidly changing demands for interoperability among heterogeneous systems leads to a paradigm shift from pre-defined control strategies to dynamic customization within many automation systems, e.g., large-scale scien-tific facilities. However, today's mass systems are of a very static nature. Fully changing the control process requires a high amount of expensive manual efforts and is quite error prone. Hence, flexibility will become a key factor in the future control systems. The adoption of web services and Service-Oriented Architecture (SOA) can provide the requested capability of flexibility. Since the adaptation of SOAs to automation systems has to face time-constrained requirements, particular attention should be paid to real-time web services for deterministic behaviour. This paper proposes a novel framework for the integration of a Time-Constrained SOA (TcSOA) into mass automation systems. Our design enables service encapsulation in filed level and evaluates how real time technologies can be synthesized with web services to enable deterministic performance.
