Abstract

There is a strong necessity for monitoring, runtime configuration, and maintenance of smart transducer networks. This paper describes tools for establishing these tasks in distributed real-time systems. A time-triggered architecture is presented, that accomplishes deterministic, reproducible monitoring of a smart transducer network without probe effects. This architecture allows access to the relevant node internal information to render all conditions observable, which cause a specific system behavior. Timeliness during dynamic reconfiguration and maintenance is preserved, which allows evolutionary changes and maintenance of the system during real-time operation. The architecture comprises both a local application and a CORBA client/server communication. We present a case study providing insight into a concrete implementation of this architecture based on the fieldbus protocol TTP/A.
