For the three-dimensional logistics simulation model can only simulate the status of automated production operation indirectly

a new PLC signal based real-time simulation model was put forward by using Flexsim software.The model obtained the PLC control signal parameters by utilizing WinCC configuration software.These parameters were put into a SQL database with the help of VB program.By using the trigger code of Flexsim simulation model

the simulation model was controlled and the real-time simulation were realized through the calling of the corresponding parameters of SQL database in real-time.The methods of PLC signal acquisition and data manipulation were highlighted.The proposed method was applied in the oil and temperature control system for the project "waste tire integrated processing and environmentally friendly equipments".
