| Abstract: | Considering the time delay cases that may occur in the PROFIBUS DP/PA hybrid networks,analyzed the time delay characters of the network as well as their affects on the system.Based on the coupler time delay,a method of inserting additional idle time TID was introduced,which decreased the message queuing delay in the PA section and enhanced the message reaction speed.Furthermore,transmission speed and other influences on networks time delay were analyzed and compared.At last the detailed method and a computa... |
