Abstract  According to the features of distribution, variety and multi-condition of air conditioner test system, an application scheme with DS100 field controller is presented, in which the DS100s with FIELDBUS and fast parameter auto-tuning are as low-layer data acquisition and control units and an industry computer is utilized as upper-layer monitor unit. Additionally, basic features of DS100 field controller and its adaptability for this test system are analyzed; feasibility of utilizing FIELDBUS technology to implement field test and control equipment information transfer is discussed. Moreover, a token transceiver schemebased on MODBUS protocol is proposed; and practical technologies and software design method of this test system is illustrated. Finally, test results on this air-conditioner test system are given.
