Abstract
According to station missing phenomenon of EM277(communication interruption) in the Profibus DP network system running process,based on the built Profibus network experiment platform,working environment factors such as the electromagnetic interference(EMI), grounding system,the settings of network parameter and so on were simulated,and combined with Profibus network message analysis,the phenomenon of EM277 station missing was analyzed. The corresponding engineering solution was proposed: reasonably setting up network system parameters,adding repeaters to realized the effective amplification and regeneration treatment,shielding and correcting grounding of network equipment and communication cables to inhibit EMI. etc. The feasibility of the scheme was verified by engineering examples.
