Application of VB and PLC in wind turbine gearbox test device monitor system

The purpose of the thesis is to control wind turbine gearbox test through the use of VB and PLC communications. The communication of VB and PLC use VB6.0 MSComm to program, this method can be fully send and receive. VB and PLC communications is stable and capable of real-time monitoring of various parameters. Practice has proved that the wind turbine gearbox test control system runs very stable and flexible.
