Real-time property analysis of single master DP/PA hybrid network control system

PROFIBUS PA is built from the PROFIBUS DP network, while both the transmission medium, transmission rate, data frame format and so on were different. Take the built typical single master DP/PA hybrid network control system as the research object, carried out a detailed analysis of representative parameter Dcycle of PROFIBUS system. On this basis, proposed the method of improving control network real-time performance, and created favorable conditions for further real-time property analysis.
