Design of Manipulator Data Commutation System Based on PLC

Abstract:

The method to realize the communication between PC and SIEMENS S7-200 series PLC is introduced through MSComm ActiveX and RS-232 serial communication protocol under VB development environment, and it is explained that the application of this way in the control system of the manipulator in detail. The focal point of introduction is about the function setting of special registers and MSComm ActiveX on VB under free-port communication in PLC, and the way to write program is described to realize receiving and sending the data of PLC.
