Service-oriented distributed measurement and control systems: A case study

The paper presents a Distributed Measurement and Control System (DMCS) applied to a physical process equipped with all the instrumentation needed to run control loops for temperature, level, flow and pressure, quantities widely found in the process industry. The system is supported by a service-oriented middleware platform based on the IEEE 1451.1 std and the Windows Communication Foundation (WCF). Tests were made to evaluate the performance of the system in terms of sampling frequency and behavior of control loops. The methodology of each experiment is described, results are analyzed and conclusions are extracted.
