A mode set is a means provided to enable the operators to control the system behavior.
Controlling the
system behavior is possible if a
machine
state set is
associated with the
mode set, in a way that enables checking if they match.
The simple reactive system ... is controlled by an On-Off switch. The states corresponding to the On-Off switch are the (Operating, Idle) engine states.
In order that the
machine
state matches the
operator's
selection, the
machine should be equipped with means to sense and report on the
corresponding state.
A micro-switch may be added to the engine, in order to engine design, to enable detecting situations when the actual behavior of the engine matches the operator's intention, as set by the On-Off switch.
