Abstract
Separation purify is an important of paper pulp productive procedure which is a complex, massive and continuous process of industrial production.
Based on the actual engineering background, the paper researches and discusses the separation of the control system designing and anglicizing. This system is a new integrated distributed control system,which integrates the industrial controlling computer system and programmable logic controller。First, according to the course of primary-election system technologies and requirements, the corresponding control programmer is research in the paper .Then the paper elaborate the selection of the DCS system and the design of hardware and software. For designing the software system, the paper emphatically analyze the electric designing principle of on-site construction,the construction of on-site control stations,and the selection of communication networks.The paper conducted the programming by the ladder diagram,utilizing the programming software of SWOPC-FXGP/WIN-C which is provided by the Japanese MITSUBISHI Company. Based on the analysis the production process, the paper worked out the logic controlling sign of the production line .Via the DAQ Factory, the integrate surveillance of the operation has accomplished the construction and management date points ,consequently the function of alarming in the operation station and standard screen operation and operation and statement printing in Station operators ,etc .
