Measurement applications in Industry 4.0: the case of an IoT–oriented platform for remote programming of automatic test equipment
A laboratory regarded as a site that collects IoT devices, and which allows remote clients to use them as an automatic test equipment (ATE) through a controller acting as service provider, is proposed herein. To assure efficiency and responsiveness, the controller is programmed as a multithreading system that takes advantage of multicore processors. The controller includes a server application that supports communication with clients by means of a TCP/IP protocol. It uses GPIB bus functionalities to control the instruments of the local ATE. It allows several clients to connect and interact with the specific resources of the laboratory. Thanks to the availability of identical sets of resources and to the underlying multithreading philosophy, client requests are processed in tandem rather than according to a classical queuing approach.
