초록

The data link layer (DLL) of Foundation Fieldbus (FF) includes both token-passing and scheduling services. Periodic data are transmitted via the scheduling service, while time-critical and time-available data are transmitted via the token-passing service. This study developed a network interface board that implements the DLL of FF. Using the network interface board, this study experimentally evaluates the delay performance of the DLL of FF. This study measured the delay performance with respect to the change of the DLL parameters of FF, and investigated the relationship between the DLL parameters and network performance. The study also compared the experimental results with the results obtained from an analytical model.
