Automatic generation of PLC automation projects from component-based models

Abstract

Industrial process measurement and control systems (IPMCS) are used in most of the industrial sectors to achieve production improvement, process optimization and time and cost reduction. Integration, reuse, flexibility and optimization are demanded to adapt to a rapidly changing and competitive market. In order to achieve these goals, the use of standards in the application field, methodologies for defining the application design and tools for supporting the development cycle are needed. This paper proposes a component-based model of the implementation of the control system under design (the hardware and software architectures). The software architecture is defined to follow the software model of the IEC 61131-3 standard for programming programmable logic controllers and the hardware architecture is composed by equipment characterised by vendor and range of product. The proposed modelling is implemented as a markup language that allows to describe models of industrial control systems (icsML). From the application model, described in the markup language, the automation project for every programmable logic controller (PLC) present in the application is automatically generated. © 2007 Springer-Verlag London Limited.
