The start/stop button is used to start/stop the PCS. Only when the button is rotated to
the "START" position, can users issue valid instruction through the WEB monitoring
interface or the background monitoring system. Otherwise, the PCS will keep in key stop
state.
If the button is in the "STOP" position, a stop instruction will be delivered to the DSP
controller, so that the PCS turns into key stop state.
