In huge production scenarios systems and processes quickly become too complex to be maintained by a human supervisor. In addition, a high rate of adaptations and process changes lead to high costs for system changes, which are in some contexts even impossible due to enterprise-spanning systems and processes. On the other hand most of the status information is not relevant for production control. The research project INTMANUS has developed a communication layer to integrate various machines into a peer-to-peer based decentralised network infrastructure. Using this network, machine data can be requested from each machine and be transferred over the network.
This paper introduces an approach to interpret messages and recognize relevant information. Such relevant information can be assembled, aggregated and routed through the network. Processes are executed within the Smart Connected Control Platform (SCCP) using a semantic model for definition and interpretation of organisational structures and processes. A concept for message interpretation and routing as well as decentralized processes execution is described. Also the join mechanism of peers into a decentralized system is using a SuperNode concept is detailed.
