  • Synoptics of Things (SoT): an open framework for the supervision of IoT devices
    Publication . Serras, Bruno; Gonçalves, Carlos; Dias, Tiago; F. G. Osório, A. Luís
    In the industry, there is a need to manage and monitor systems and their associated devices. This process can be quite complex when the technological landscape is composed of several heterogeneous systems. In such scenarios, both the systems and their devices can be from different suppliers, each one with its own interfaces, often proprietary and non standardized. Moreover, several different administrators can be responsible for the supervision of a system, which greatly complicates the process of supervising multiple systems. Yet, overviewing a technological landscape can be facilitated by the concept of Synoptics, as a fundamental part of a supervisory control and data acquisition system. As modern applications become more and more web based, it makes sense to use web browsers to implement the concept of Synoptics. In this paper, we present the Synoptics of Things (SoT) framework to extend the Synoptics concept to the web domain. The proposed SoT framework explores the concept of Web Components as a standard to enable the development of custom and reusable components for modern web browsers. Such components, or Widgets-IoT, as we call them, can function as an abstraction of both IoT devices and informatics systems, facilitating the interaction with the supervising operators. Accordingly, we present and discuss the use of the SoT framework in an Informatics System of Systems reference implementation to monitor and control the involved systems and the various executive services that compose them.

  • Integration of remote interfaces for industrial automation applications
    Publication . Santiago, Daniel; Cordeiro, Armando; Vieira De Brito Almeida, Maria Da Graça
    This paper presents a remote interface solution for industrial automation applications based on the integration of automation Fieldbuses with different technologies. This solution is obtained by the connection of an Industrial Ethernet Fieldbus with a classic Fieldbus, through a strategy of software and hardware compatibilization. The compatibility of the software is achieved through the AXC 1050 PROFINET controller, communicating using the PROFINET and Modbus TCP/IP protocols and the programming of the Modbus RTU protocol, in the Siemens S7-215-2 PLC, in freeport mode, creating a bridge between both devices and their inputs/outputs variables. The development of this solution allows access to all existing equipment through a commercial Ethernet Fieldbus and the control of the S7-215-2 from other equipment of the Fieldbus, assigning new features to this controller that originally did not have this capability.
