摘要
在工业自动化领域,工厂的控制常由可编程逻辑控制器(PLC)执行。随着自动化应用越来越小型化、柔性化,在这些领域使用、设计并维护一个完整的、基于硬件的PLC是不经济的,基于云的软PLC可以成为控制即服务的解决方案。介绍了一种基于云的多实例、可扩展的软PLC系统架构,并基于该模式评估了系统的实时性和可扩展性。最后,对未来工业应用中基于云的控制现场场景提出了展望。
In the field of industrial automation,factory control is often performed by Pro-grammable Logic Controller(PLC).With the application of automation becoming more and more miniaturized and flexible,it is uneconomical to use,design and maintain a full hardware-based PLC in these fields.The software PLC based on industrial cloud can become a Control-as-a-Service solution.This paper introduces a multi-instance and scalable soft-PLC system architecture based on industrial cloud.Furthermore,the real-time and scalability of the architecture based on industrial cloud are evaluated.Finally,an outlook to the prospect of cloud-based control scene in future industrial applications is given.
