Discussion on the Application of Electronic Marshalling Control System
With the development of technology in the petrochemical industry,the requirements for investment cost,construction cycle,maintainability and intelligence of the control system are also getting higher and higher.To comply with the trend,the electronic marshalling technology of general IO combined with local IO cabinet is introduced.The differences between the traditional marshalling technology and the electronic marshalling technology are compared with the aspects of IO card parts,marshalling form,reliability,engineering cycle,later maintenance and so on.The application design of electronic marshalling is discussed from the aspects of signal and network,electronic marshalling cabinet arrangement,explosion-proof,power supply and grounding.Combined with the actual project application situation,the advantages of electronic marshalling technology is summarized,and certain reference for the popularization and application of electronic marshalling technology is provided.
