Abstract:Human machine interface development of rapid configuration has become a current trends in the field of touch screen PC interface display. A standard industrial communication protocol can realize standardized equipment access of multiple areas. Combined with the design of electronic products demand, this paper realizes the host computer interface development of WEINVIEW touch screen as human computer interaction platform and software system framework of the standard MODBUS RTU protocol as data transmission under RS232C electrical interfaces. The supporting EB8000 software has been used to design human machine interaction, which has friendly interface and rich modeling resources and can be learned easily and operated conveniently, reducing the developer quantities of interface design. MODBUS RTU protocol frame format is used, which is simple, compact, easily to use and interact with the console computer, meeting developer & users' product development. Finally, an instrument product software system including host computer, communication module and console computer is demonstrated.
