Abstract： In order to improve the performance test efficiency of the hydraulic torque converter，the computer technology was investigated to build the hardware control scheme. And graphical programming language LabVIEW was used as PC software development tools，combined with Siemens S7-300 PLC，the real time monitoring of the test process was realized. And how to use OPC in LabVIEW to connect the computer and the programmable logic controller online to control the motion of the motor was studied. The experimental results show that the system is stable and reliable，and it enhances the automation of the torque converter performance test ，shortenes the test cycle and improves the working efficiency.
