Service-Oriented Architecture in Industrial Automation Systems - The case of IEC 61499: A Review
This work addresses the need for more adaptable automation systems in industrial settings, but it is incremental as it builds on existing SOA and IEC 61499 frameworks.
The paper reviews literature on Service-Oriented Architecture (SOA) in industrial automation, focusing on a formal model and execution environment based on IEC 61499 to enable flexible and dynamically reconfigurable systems, as demonstrated in a case study.
In the paper by W. Dai et al. (IEEE Trans. On Industrial Informatics, vol. 11, no. 3, pp. 771-781, June 2015), a formal model is described for the application of SOA in the distributed automation domain in order to achieve flexible automation systems. A service-based execution environment architecture based on the IEC 61499 Function Block model is proposed and a case study is used to demonstrate dynamic reconfiguration. In this letter, a review of the literature related to the use of SOA in Industrial Automation Systems is given to set up a context for the discussion of the proposed in the above paper SOA IEC61499 formal model. The presented, in the above paper, formal model and execution environment architecture are commented towards a better understanding of the potentials for the exploitation of the SOA paradigm in the industrial automation domain.
