Abstract: A programmable control device includes an input unit, a memory unit, an execution unit, a monitor unit and an output unit. The input unit has at least one input terminal for receiving an input signal. The memory unit defines plural feature tables for corresponding functional units, the feature table defining a state of the functional unit and an event to be executed according to an input signal corresponding to the state. The execution unit executes an event corresponding to the functional unit triggered by an input signal, and thus produces a driving signal and/or an output signal. The monitor unit monitors the execution unit to trigger a corresponding functional unit and to use the driving signal as an input signal for the functional unit to execute a corresponding event. The output unit has at least one terminal to output the output signal.
