Punching is lost, and just can not be simulated and be tested in existing model measurement.
In model in existing emulation testing, valve control function can not carry out deeply, comprehensively testing.In existing model,
Some functions of valve module fail to embody in software model.Such as valve module middle valve plate return inspection signal in software model just
Do not embody.And multichannel is returned when examining dropout, and protection act may be caused.The design of existing this part of model deficiency, because
Without having the ability of complete test valve control function.
