The paper presents a procedure for analyzing the performance of distributed data communication networks for autonomous manufacturing and process control systems. Selection of an appropriate protocol is an important step in the distributed data communication and control system (DDCCS) network design because the feedback control system, in addition to the sampling time delay, is subject to transport delays due to data latency in the network. SAE token ring, SAE linear token bus, and MIL-STD-1553B protocols have been analyzed in view of the DDCCS network design requirements. The results of closed loop control system simulations are presented to demonstrate how data latency generated by the network access protocols could degrade the dynamic performance and stability of the controlled process.
