PROBLEM TO BE SOLVED: To reduce the trouble of input work of characteristic information of a regulator-valve to a positioner, and to reduce the possibility of occurrence of human errors.SOLUTION: A regulator-valve 1 is provided with a regulator-valve characteristic information holding unit 1-3, and makes it hold information such as an aperture value of the valve of the regulator-valve, a code of the aperture of the valve, a model number of the valve, a model number of the regulator-valve, and a unique identifier of the regulator valve, as characteristic information of the regulator valve 1. A positioner 2 is provided with a regulator-valve characteristic information reading unit 2-2 and an information conversion setting unit 2-3. The regulator-valve characteristic information reading unit 2-2 receives a reading starting command and reads characteristic information of the regulator-valve 1 held in the regulator-valve characteristic information holding unit 1-3 to transmit the characteristic information to the information conversion setting unit 2-3. The information conversion setting unit 2-3 converts the characteristic information of the regulator-valve 1 into a parameter value to set it in a valve control calculating unit 2-1. |
