Grafchart for recipe-based batch control
DOI:10.1016/S0098-1354(98)00008-8.png)
Abstract
En 中文
The paper presents how Grafchart, a toolbox based on Grafcet, object-oriented programming ideas and high-level Petri nets, can be used to implement a batch control recipe execution and recipe representation system. A brief overview of Grafchart is given and it is shown how its concepts fit the models defined in the recent ISA batch control standard S88.01. A simulated batch process cell scenario is presented together with several alternative ways of representing batch recipes. (C) 1998 Elsevier Science Ltd. All rights reserved.
