Title:
RANGE SWITCHING DEVICE OF CONTROLLER
Document Type and Number:
Japanese Patent JPS58195202
Kind Code:
A
Abstract:
PURPOSE:To make a controller, which is provided with the range switching function, efficient, by providing an operation unit for range switching, an operation unit for digital display of a controlled variable, and an operation unit of a manipulated variable. CONSTITUTION:An operation unit U1 is the operation unit of coefficients corresponding to the range switching, and an operation unit U2 is the operation unit for digital display of a controlled variable and an operation unit U3 is the operation unit of a manipulated variable. The coefficient output from the unit U1 is inputted to units U2 and U3. The unit U1 is connected to range changeover switches S1 and S2, and a controlled variable PV is inputted to units U2 and U3, and a manipulated variable MV is outputted from the unit U3. The output of the unit U2 is supplied to a digital display ID. By this constitution, the controller provided with the range switching function is made efficient.
