Requirements for Testing and Validating the Industrial Internet of Things

The latest advances in industry have been accomplished within the 4th Industrial Revolution, mostly noted as Industrie 4.0. This industrial revolution is boosted by the application of Internet of Things (IoT) technologies into the industrial contexts, also known as Industrial Internet of Things (IIoT), which is being supported by the implementation of Cyber-Physical Production Systems (CPPS). In this context, most of the existing work concentrates on developing IIoT models and CPPS architectures, laking the identification of validation requirements of these platforms. By rushing into releasing state-of-the-art IIoT applications, developers usually forget to implement methodologies to validate these applications. In this paper, we propose a list of requirements for IIoT platform validation, based on its architecture, as well as in requirements established by the industrial reality. A CPPS case study is presented, in order to illustrate some of these requisites and how validation of these type of system could be achieved.
