Distributed Control Patterns using Device Profile for Web Services

Automation systems are changing from the centric-controlled approach to a more flexible and autonomous behavior. The contribution to this philosophy comes from several technologies, including service-oriented concepts. This work focus on some open points of enhanced communication and control patterns and presents it in form of a multi-use communication module. For the development of such systems, the SOA4D implementation of device profile for Web services (DPWS) was used. The specified communication structure that works on top of the DPWS toolkit can be integrated in software applications targeting but not limited to embedded devices. The resulting interaction patterns also establish a stronger association to real life services and define flexible communication routines between service requester and provider.
