Abstract [sv]

Detta examensarbete presenterar försöket att integrerar informationsarkitekturen - Line Infrastructure System Architecture (LISA) i en reell informationsarkitektur av en existerande industriell produktionslina. LISA är ett koncept för att sammanföra klassiska dataarkitekturer för produktionslina med nya metoder som uppkom med Sakernas Internet (Internet of Things) och Industri 4.0 trenden. Examensarbetet syftar till att bevisa den allmänna kompabiliteten av befintliga system från den tiden före Sakernas Internet med moderna datainsamlings och distributionsteknologin. För detta syfte analyserades Scanias motorblocktillverkningslina i Södertälje och potentiella gränssnitt har identifierats. Data som har generats i en PLC miljö har överförts och anpassats till ett format som enkelt kan interpreteras av en modern meddelandehanterare, genom detta har datas komplexitet reducerats till ett enkelt meddelandeformat. Utöver detta har PLCernasom används på linjen omprogrammerats så att de stödjer ett applikations protokoll som i sin tur stödjs av meddelandehanteraren. Resultatet visar att äldre generationens PLCer kan integreras i moderna informationsarkitekturer så länge som de har ett Ethernet gränssnitt och kan kommunicera via det. I studiens fallet data som har genererats i produktionslinjen i en PLC miljö har framgångsrikt indexerats i ett företags sökmotor och därmed gjorts tillgänglig i en webbmiljö. Studien har visat att utrustningen som har använts i det undersökta fallet har förmågan att integreras i ett modernt Line Infrastructure System Architecture.

Abstract [en]

This thesis presents the approach to integrate the Line Infrastructure System Architecture (LISA) into an information infrastructure of an existing industrial production. The LISA is an approach to reconcile classical production line data structures with new methods that emerged within the Internet of Things and Industrie 4.0 approaches. The thesis aims to prove a general compatibility with legacy equipment from the pre Internet of Things area with modern data collection and distribution technologies. For that purpose the engine block production line at Scania in Södertälje has been analysed and possible interfaces identified. There the data generated in a PLC environment was casted into a format that can easily interpreted by a modern message broker and the complexity of the transferred data was reduced to a simple message format. Further were the PLCs reprogrammed to implement an application protocol supported by the used message broker. The results show that PLCs of older generations are able to be integrated in a modern information infrastructure as long as they provide Ethernet interfaces. In the case of the study, the data generated in a production line within a PLC environment were successfully indexed in an enterprise search engine and thereby made available in a web environment. The study showed that the legacy production equipment used in the investigated case has the capability to be integrated into a modern Line Infrastructure System Architecture.
