default void	stopButtonReleased(StopButtonEvent stopButtonEvent) Invoked when the stop button is disengaged.

Method Detail

stopButtonPressed

void stopButtonPressed(StopButtonEvent stopButtonEvent)

Invoked when the stop button is first pressed. The hardware will have a flashing LED next to the stop button to indicate a paused state.

While the OEM implementation of the control lab software would halt program operation in this state, the hardware does not hamper the flow of input data and continues to track output commands, only the physical outputs are prevented from receiving power. Actual behavior is left to the implementor of the interface.

Parameters:

stopButtonEvent - The event that triggered this callback.

stopButtonReleased

default void stopButtonReleased(StopButtonEvent stopButtonEvent)

Invoked when the stop button is disengaged. The hardware will have an unlit LED next to the stop button to indicate the computer is connected. Any outputs that were powered prior to the stop button being pressed will return to their prior state. Any output commands issued while in the stopped state will also take effect.

The default implementation is no-op.

Parameters:

stopButtonEvent - The event that triggered this callback.
