Controller-based IIoT infrastructure and enabling technologies: An overview for design configuration

This article presents an overarching overview of controller-based Industrial Internet of Things (IIoT) infrastructures, with emphasis on the prevalent enabling technologies. Through a critical analysis, the study is used to reveal the determinants for choosing IIoT infrastructure and enabling technologies, given the type of field device whether microcontroller or Programmable Logic Controller. Findings from the analysis motivate proposal for generalized configurations for the design of IIoT systems to harmonize the multitude of conceivable designs.
