| Abstract: | In this paper, a method of Fail-safe test for the transmission of the information through the interface between Fail-safe Fieldbus Physical layer .and Data link layer is introduced . First , we present the basic conception of the Fail-safe information transmission system, the simulation of the communication channel and the massage transferring model on the PHL-DLL interface . Then we describe the method of the Fail-safety test. In order to increase the efficiency, we adopted the Important Sampling. |
