摘要：PROFIBUS-DP是一個日趨流行的工業(yè)現(xiàn)場總線協(xié)議。目前，越來越多的工業(yè)控制系統(tǒng)采用PROFIBUS-DP。討論了在塑料加工擠出機(jī)上引入該工業(yè)網(wǎng)絡(luò)，將舊系統(tǒng)改造為PROFIBUS系統(tǒng)的方法。改造后的系統(tǒng)結(jié)構(gòu)精簡，抗干擾能力大大提高。

Abstract：In this paper, a method of upgrading a control system of the plastics extruder machinery from the non-FCS system to PROFIBUS-DP system, which results in hardware simplification and interference reduction, is discussed.
Keywords：PROFIBUS-DP, FCS, plastics extruder
