PURPOSE: A middleware technology based on a device model is provided to develop middleware, which can be used for various devices and communication methods, at low costs in a shorter time only with the exchange of device model information without additional development. CONSTITUTION: An application (100) transmits parameter identification (ID) and conversion data to a driver (400) through a common application program interface (API) (500). The driver respectively converts addresses and data with parameter information and data information corresponding to a device model (410). An address converter (420) performs the address conversion. A data converter (430) performs the data conversion. A protocol converter (440) performs protocol conversion.
