Control Apparatus and Method based Software

The target device by the program, is disclosed a control apparatus and method for real-time management, and control. The control apparatus of an interior of a two-wire serial fashion destination device external signals including a command to edit the control program from the control unit, an external host to control the target device according to the stored control program and control parameter or by adjusting a control parameter circuit a conversion unit for converting into the signal for setting or investigate the status of input and output pins for connecting, respectively, in accordance with an instruction included in the converted internal signal to directly access the internal circuit of the target device set for the state of the input and output pins or irradiation by comprising an internal interface which can be the control program and control parameters embedded in the target device, an effect of facilitating the management and control of the target device to be changed from the outside by the host.
