Migration of a legacy plant lubrication system to SOA

Supervision and control systems are being deployed in industrial environments such as mining plants and manufacturing facilities to ensure a continuous and effective production at a minimum cost. Such systems monitor a whole range of devices and collect their data for several purposes like maintenance and control operations. At the same time, Service Oriented Architecture (SOA) is getting more popular than ever in most application domains, from IT to device level, and particularly for those industries whose continuous efforts to increase the overall plant and equipment effectiveness lead to new requirements on systems openness, integration, availability, maintainability and performance. This paper presents how a legacy control and monitoring system could migrate to SOA, the architecture principles and the main benefits and limitations based on results validated on a pelletizing plant lubrication system.
