Servo is closed loop control, encoder, after receipt of the pulse signal according to the pulse signal, the results of the action, and feedback in the form of a pulse signal to the servo controller, judging by the servo controller, whether the action implementation in place, need to take any remedial measures and so on, these are all servo controller automatically to judge, don't know say understand have no?
The upper part of the servo controller is the general term for the device that provides the control signal to the servo controller. For example, the PLC, the industrial control machine, etc., can be called the top machine.

PC refers to the computer, can be directly send control commands are generally PC/host computer/master computer/upper computer, screen signals change (hydraulic pressure, water level, temperature, etc.). The next machine is a computer that directly controls the status of the device, typically a PLC/single chip microcomputer/slave computer/lower computer. The command issued by the above machine is first given to the next machine, and the next machine is interpreted as the corresponding timing signal to control the corresponding device directly. From time to time, the next machine reads the status data of the device (usually the analog quantity) and converts it into digital signal feedback to the top machine. In short, there is a lot of difference, but there is a lot of variation: both the up-and-down machines need to be programmed, and there are specialized development systems.
