Re-usable software design for programmable logic controllers

Abstract: It is the aim of this paper to present a model conceived for supporting the initial, critical phases of PLC software life cycle, namely requirement specification, requirement analysis and software design, to obtain reusable code. The model, named EASIER, is based on an object-oriented paradigm where the message-method mechanism is replaced by the law and action primitives, since they are more suitable to cope with the real-time, cyclic nature of PLC software. Software re-usability is pursued by identifying ind… Show more
