The fast development of the wireless technologies has opened new potential for wireless networked process control system. With wireless network, the scalability of the systems will be extended. In order to analyse and evaluate the efficiency of a wireless networked process control system, a real-time network simulator is required. In this paper, we introduce True Time, an open source Simulink package for simulation of networked control systems. By using True Time, we present an analysis and evaluation of the effects of communication network to the performance of a wireless process control system. Wireless environment is simulated using True Time toolbox. Other parts of the system such as actuator, sensor, controller are real devices.
