A Framework for the Implementation of Industrial Automation Systems Based on PLCs
This addresses inefficiencies in industrial automation development for engineers, but it appears incremental as it builds on existing standards and technologies.
The paper tackles the suboptimal design of industrial automation systems by proposing a system engineering process based on the new IEC 61131 standard with Object Orientation, utilizing SysML and UML for abstraction and IoT for integration.
Industrial automation systems (IASs) are traditionally developed using a sequential approach where the automation software, which is commonly based on the IEC 61131 languages, is developed when the design and in many cases the implementation of mechanical parts have been completed. However, it is claimed that this approach does not lead to the optimal system design and that the IEC 61131 does not meet new challenges in this domain. In this paper, a system engineering process based on the new version of IEC 61131, which supports Object Orientation, is presented. SysML and UML are utilized to introduce a higher layer of abstraction in the design space of IAS and Internet of Things (IoT) is considered as an enabling technology for the integration of Cyber and Cyber-physical components of the system, bringing into the industrial automation domain the benefits of these technologies.
