【Abstract】 In this paper, the communication function of simulation operating system for container crane is introduced. First, Winsock control of VB6.0 is used to conduct the communication between computers. Then, the communication between computer and PLC is realized by Cimplicity, which works under Windows NT operation system. Last, with the help of DDE (Dynamic Data Exchange), the data exchange between VB and Cimplicity is accomplished.更多还原
