The Chapter presents a service-oriented middleware platform that takes advantage of the communication model provided by WCF services and the information model defined by the IEEE 1451.1 clause. The proposed platform was used to control a physical process equipped with all the instrumentation needed to run control loops for pressure, level, flow and temperature, quantities widely found in the process industry. Tests were made to evaluate the performance of the system in terms of sampling frequency, communication delays and behavior of control loops. The methodology of each experiment is described, results are analyzed and conclusions are extracted.
