EPA (Ethernet for Plant Automation) resolves the nondeterministic problem of Ethernet through sub-segment topology and deterministic scheduling mechanism. In this paper, the EPA scheduling mechanism is implemented by simulation tool. And the influence of EPA scheduling mechanism on network performance is shown in the simulation result. According to the study, the real-time performance of EPA periodic...
Simulation is an indispensable technique to evaluate the performance of computer networks, because the continuous growth of network scale and diversity. In this paper, the modeling of EPA protocol in OPNET modeler, a simulation tool of control system network is developed. These configurable EPA protocol models allow to easily build factory numerical device control system (FNDCS) simulation with different...
