Abstract: Enterprise integrated automation is the general trend of industrial control development. The combination of control network and information network provides comprehensive information services for enterprise as production information, production control, planning decisions and sales management as well. The industrial control network and information network integration can realize the information and resources sharing among the enterprises networks and further improve the enterprises informationization and integrated automation level so as to achieve the situation that the enterprise production and management is more efficient and more flexible. The study introduces the information integration of the fieldbus control network and the information network and analyze the information integration technologies such as internetworking, dynamic data exchange (DDE), Open Database Connectivity (ODBC), OLE for Process Control (OPC), control network and information network with unified protocol standards. the integration application of bus system is illustrated with the example of Controller Area Network (CAN) bus.
