Operating method for a metallurgical plant comprising at least one first plant part, - wherein a plurality of operating states (Zi) is stored within a control unit of the first plant part as a concatenated or unconcatenated list, - wherein the particular operating state (Zi) is defined by particular first operating parameters, second operating parameters, and a state condition, - wherein the first plant part is operated in succession in a sequence of operating states (Zi), - wherein the first operating parameters are adjusted without assistance from the control unit of the first plant part, - wherein the control unit of the first plant part initially determines the particular operating state (Zi) and then controls the plant part according to the second operating parameters assigned to the determined operating state (Zi), - wherein an operating result, which was established on the basis of the operation of the first plant part according to the first and second operating parameters (BP1, BP2), is recorded, - wherein at least the operating result is transmitted from the control unit of the first plant part to a computing unit, - wherein the computing unit varies the second operating parameters, but not the first operating parameters, and thereby determines varied second operating parameters (BP2') associated with the first operating parameters, - wherein the computing unit transmits the varied second operating parameters (BP2') back to the control unit of the first plant part, and - wherein the control unit of the first plant part stores the varied second operating parameters (BP2') instead of the previously stored second operating parameters of the corresponding operating state (Zi) in the list of operating states (Zi), and therefore the control unit of the first plant part uses the varied second operating parameters (BP2'), after the transmission of the varied second operating parameters (BP2'), when the first operating parameters are established. - wherein a plurality of operating states (Zi) is stored within a control unit of the first plant part as a concatenated or unconcatenated list, - wherein the particular operating state (Zi) is defined by particular first operating parameters, second operating parameters, and a state condition, - wherein the first plant part is operated in succession in a sequence of operating states (Zi), - wherein the first operating parameters are adjusted without assistance from the control unit of the first plant part, - wherein the control unit of the first plant part initially determines the particular operating state (Zi) and then controls the plant part according to the second operating parameters assigned to the determined operating state (Zi), - wherein an operating result, which was established on the basis of the operation of the first plant part according to the first and second operating parameters (BP1, BP2), is recorded, - wherein at least the operating result is transmitted from the control unit of the first plant part to a computing unit, - wherein the computing unit varies the second operating parameters, but not the first operating parameters, and thereby determines varied second operating parameters (BP2') associated with the first operating parameters, - wherein the computing unit transmits the varied second operating parameters (BP2') back to the control unit of the first plant part, and - wherein the control unit of the first plant part stores the varied second operating parameters (BP2') instead of the previously stored second operating parameters of the corresponding operating state (Zi) in the list of operating states (Zi), and therefore the control unit of the first plant part uses the varied second operating parameters (BP2'), after the transmission of the varied second operating parameters (BP2'), when the first operating parameters are established.
