Research Of PLC Remoting Network Control System Of Synthesis Based On Net Configuration Software WebAccess

Network has caused a series of changes as it was used in control system,especially the participation of FCS, Configuration, information exchanges OPC),Web and so on.With the wide application of the network technology and Internet,and the fast Development of FCS and the mature net technologies are adopted into automation,such as:Ethernet,OPC, ActiveX, Web and network security ,real-time database,the traditional control system is becoming more open,intelligent,networking and distributing.The fast development of Web technology provides the remote control a new way,and it is a popular trend to design an industrial remote supervising and control network.The subject we did just following these trends of the time, designed heterogeneous system remote network control based on net configuration software WebAccess, realized integration,and information exchanged of different control netwok and monitor control.Firstly,we went to the totally design of system, according to the control function of bottom system and the demand of system totally network control, considered distributed control, layering network, concentrated management, remote control as the designing mind, analyzed and defined that used new net configuration software WebAccess software to realize two heterogeneous systems integration control case. Then , made a layering analysis to the system from top to bottom. Completed the hardware and software design of Mitsubishi control system of combination with real and virtual object and Siemens material handling control system. Then finished the communication and configuration of RS485 and Profibus field-bus,and built the middle control layer considered CGS and WinCC as main part. At last integrated two different control net and control system by WebAccess,and realized the information exchanged among WebAccess and MCGS , Wincc by OPC. Finished the design of project node and SCADA node ,realized good net management function ,monitor operation and maintain with unlimited clients and provided full terrace of IE to users.The debug results to the whole system indicated that the results met the demands of system and the plan of system design is reasonable ,original and practicable ,and can realize two direction exchange of data information.
