Design And Implementation Of Communication Converting Platform Base On OLE For Process Control

The DCS system based on OPC’s research and development platform,communication protocol conversion is introduced in the thesis.. The system can bewidely used in DCS (distributed control system) and third-party equipment or dataexchange between applications. In the work of DCS with third-party devices on thecurrent means of communication in-depth study and analysis of the actual needs of thehighly abstract works of various communication methods and protocols, based on theproposed detailed requirements of the software and design ideas, in order to achieveDCS By way of non-OPC OPC device communications protocol. So, a detailed study ofobject-oriented design and OPC data access specification, and benefit analysis of thecurrent system when MACSV disadvantages of communication with third-party devicesand the future direction of development of communications equipment, obtained thespecific design of the software Program. Finally, the use of object-oriented thinking, theuse of VC++development and design of the OPC-based platform for communicationprotocol conversion,Its flexible configuration, greatly reduce the difficulty of the worksite commissioning personnel can simultaneously connect a variety of types of devicesto support different protocols. And can be compatible with any third party OPC Client,OPC Client for the support of the HMI/SCADA, RMIS, MES and other applicationscan plug and play...
