| Abstract: | The paper presents the application of S7-200 series PLC in the technical reform of electric control system of collection-roll up hydraulic device in wire-rod plant of Panzhihua Steel Group. PLC has been successfully used not only to substitute the controlling and protective functions of the original relay control system but also to add the function of electrical energy saving, thus optimizing the system. The paper also explains the technological process and its control prlneiples. |
