Abstract

This work proposes a novel methodology for translating industrial control systems, described in the standard ISA 5.1 (Piping and Instrumentation Diagrams P&ID) and the associated process and operation narratives, into Petri net models. In a first stage, the P&ID information and the process and operation narratives are translated into standard tables. Since narratives are given in natural language, they are a potential source of errors, for this reason a semi-automatic error removal mechanism is included. Next, the tables’ information is translated into plant and specification models, described by Labeled Petri nets (LPNs). Based on these LPNs, a LPN controller can be synthesized to drive the plant behavior according to the specification, by applying the regulation control approach introduced in the literature, resulting in PLC code for the automation of the process. The proposed approach saves time in the controller design, its commissioning, and debugging, in comparison with traditional trial-and-error approach.

将管道和仪表图 (P&ID) 转化为标签 Petri 网以自动生成 PLC 代码的方法学

这项工作提出了一种新颖的方法，用于将标准 ISA 5.1（管道和仪表图 P&ID）中描述的工业控制系统以及相关的流程和操作说明转化为 Petri 网模型。在第一阶段，P&ID 信息以及流程和操作说明被转换成标准表格。由于叙述信息是以自然语言提供的，因此可能会产生错误，为此，我们采用了一种半自动除错机制。接下来，表格信息被转化为工厂和规格模型，这些模型由标记 Petri 网（LPN）描述。在这些 LPN 的基础上，通过应用文献中介绍的调节控制方法，可以合成一个 LPN 控制器，以根据规范驱动工厂行为，从而生成用于流程自动化的 PLC 代码。与传统的试错法相比，建议的方法节省了控制器设计、调试和调试的时间。

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
