Abstract:
Remote process control and supervision applications developed over the TCP/IP networks require special communication models and techniques, which can guarantee the real-time and safety restrictions inherent to automation systems. This paper presents a reservation-based communication system architecture and a communication model based on data flow analysis that offer a good control over the transmission time of critical data. As part of the model, an analytical method is proposed that allows apriory evaluation of the required minimum bandwidth necessary to assure the satisfaction of real-time transmission restrictions.
