In addition, the performance testing methods of CMC are also studied, including system level power of CMC and benchmark performance testing based on PLCopen standard. Finally, the application and results of the test verification system designed and implemented in this paper are discussed. The availability of the test verification system designed in this paper is verified. It can test and verify the logic control function of the CMC system and the function of motion control, and can effectively test the key performance indexes of the CMC.
