Abstract
Aiming at the domestic application status of OPC technology,and taking the access specification of OPC data as the basis,the OPC data access server was developed by using domestic MultiBus-RTU series module based on ModbusTCP pro-tocol. The OPC development tool OM_OPCSvr.dll created by OPCMaster company is adopted to achieve the development of OPC data access server. The exchange channels of data are provided between the Modbus device and the OPC client with the Ether-net. The function framework of the server was constructed by designing the structure and operation process of OPC data access server. Based on the Modbus TCP OPC server and the Windows platform,the communication driver module and user interface were planned by initializing the server,and then the OPC data access server was realized. The further test to the OPC server found that the server has reliable stability,and can save the cost effectively,reduce the number of communication driver,and shorten the development cycle.关键词
