The fourth industrial revolution aims to achieve greater productivity, also seeking to improve the quality and efficiency of production processes. For this, the use of information and automation technologies together becomes indispensable. Collaborative automation through the sharing and use of services has been a recent paradigm in the quest to obtain a distributed, flexible and integrated on network architecture. In this article, the development of control and automation applications as a service using a Microservices Oriented Architecture is investigated. The architecture is elaborated using the Moleculer framework, which simplifies the development of microservices and applications that make up the Microservice Oriented Architecture used in this work. The development and evaluation of several services are presented, such as Data Acquisition (DAQ), Programmable Logic Controller (PLC) and PID Controller (PIDPlus). The experimental results in different scenarios demonstrated the feasibility of implementing control and automation applications as a service. A relevant advantage that this type of architecture provides is interoperability through automatic network communication between applications and microservices, which is required for Industry 4.0.

工业自动化即服务：工业 4.0 的新应用


第四次工业革命旨在提高生产力，同时寻求提高生产过程的质量和效率。为此，信息和自动化技术的共同使用变得必不可少。通过共享和使用服务的协作自动化已经成为寻求分布式、灵活和集成的网络架构的最新范例。在本文中，研究了使用面向微服务的架构作为服务来开发控制和自动化应用程序。该架构是使用 Moleculer 框架进行阐述的，该框架简化了构成本工作中使用的面向微服务的架构的微服务和应用程序的开发。介绍了数据采集 (DAQ)、可编程逻辑控制器 (PLC) 和 PID 控制器 (PIDPlus) 等多种服务的开发和评估。不同场景下的实验结果证明了将控制和自动化应用程序作为服务实现的可行性。这种类型的架构提供的一个相关优势是通过应用程序和微服务之间的自动网络通信实现互操作性，这是工业 4.0 所需要的。
