The paper addresses the issue of the worst-case performance evaluation of the predictive p-CSMA scheme used as the MAC protocol in LonWorks/EIA-709 networked control systems. The performance of the predictive p-CSMA significantly depends on the specification of the traffic scenario since it determines the efficiency of load prediction built in the protocol. The analytical approach based on Markov chains is applied. Transition probabilities for a general-case load scenario are derived and
