摘要

在基于模型的设计中，为了涵盖自动化系统的实时特性，不仅要对功能建模，还要对运行在实时控制器上的控制程序的行为建模。本文介绍了一种在模型级上对可编程逻辑控制器(PLC)的功能和时间行为进行建模和评估的方法。将由UML状态图组成的控制算法扩展为控制器的执行模型(也称为状态图)。该方法被集成到一个以生产系统为重点的基于模型的工业控制系统设计系统中。一个例子将用来说明一个基于模型的设计系统的好处，它确实包含了控制器的实时方面。

Modelling the real-time behaviour of machine controls using UML statecharts

For covering the real-time characteristics of an automation system during model-based design it is essential to model not only the function but also the behaviour of the control programs running on a real-time controller. This paper introduces an approach to the modelling and evaluation of the functional and time behaviour of Programmable Logic Controllers (PLC) on model level. The control algorithm consisting of UML statecharts is extended with an execution model of the controller which is also given as a statechart. The approach is integrated into a model-based design system for industrial control systems focusing on the field of production systems. An example will be employed to illustrate the benefits of a model-based design system which does incorporate real-time aspects of the controller.
