Aiming at the problems of low number of experimental equipment per capita,low classroom efficiency and high equipment failure rate in PLC or pneumatic course teaching,a full virtual simulation system based on OPC interface technology was proposed to realize multi-software co-simulation.Taking pneumatic manipulator as an example,this paper uses MX OPC Server as a data server to provide access interface to control process data,and realizes co-simulation and data linking and embedding of pneumatic software FluidSIM,Mitsubishi PLC programming software GX Works2,mechatronics conceptual design software NX MCD and other software.When the method is put into the actual teaching process,the data interaction between the software is synchronized in real time,and the operation of the manipulator reaches the expected effect,which has certain reference value and significance for improving the efficiency of equipment design,shortening the debugging time and development cycle.
