摘要
A logic device for use in the case of the control of a process comprising:– a plurality of inputs (in1, in2, in3) for receiving process output signals (cv1, cv2, av);– a further input to the input of a control variable (ocv), which a desired value (ocvSp) is associated with;– a plurality of outputs (out1, out2, out3) for delivery of control signals (mv1, mv2, mv3) for the control of the process, wherein each of the plurality of outputs (mv1, mv2, mv3) an associated restriction limit value (mv1Con, Mv2Con, Mv3Con) has;– a return path (25), of a selected output of the plurality of outputs (out1, out2, out3) with the further input directly or via an amplifier (23); and– a logic unit (14) which, with the inputs (in1, in2, in3) and the outputs (out1, out2, out3), and is configured such that it for controlling the process the control signals (mv1, mv2, mv3) for the plurality of outputs (out1, out2, out3) with the use of the plurality of inputs (in1, in2, in3) and of the further generated at the outset, and is designed in such a way that the selected output until the further input of the associated reference value (ocvSp) has reached,wherein the logic unit (14) further has a rated value setting unit, which is so designed that they the set value of a first setpoint selection means to a second desired value setting means sets, when one of the outputs, which is not the selected output is, in this case is the associated restriction limit value (mv1Con, Mv2Con, Mv3Con) for this output is reached or exceeded to to, andthe first setpoint selection means a value which is equal to the restriction limit value (mv1Con, Mv2Con, Mv3Con) the selected output, and wherein the second setpoint selection means is a value of the in relation to the restriction limit value of the selected output is loosened.
