Abstract
The Industry 4.0 starts the digitalization process and for this have been using new technologies as Internet of Things, Cloud Computing, Service Oriented Architecture and Control Systems in network. The integrated use of these technologies in automation and process control applications provide advantages, such as vertical interoperability and standardization of communication through networked service sharing. In this article, the redundancy of industrial process controllers is studied and the development of a redundant controller is investigated using an automation architecture oriented to microservices. The redundant controller is based on a modification of the PIDPlus algorithm to network control for operation as a microservice. Additionally, a redundancy application (orchestrator) is responsible for orchestrating microservices and recording control variables, allowing the sharing of data from process variables among redundant controllers (replica). The experimental results obtained in a pilot plant in different scenarios demonstrated feasibility and efficacy in the redundancy implementation of process controllers as a service, as well as the advantages of this type of implementation.
