摘要

In many cases initially - / much compartment output - logic device for use in the case of the control of a process comprisinga plurality of inputs, which are designed such that they process output signals are received;a further input, which has an associated reference value;a plurality of outputs, which are designed such that they control signals for the control of the process to deliver;a return path, of a selected one of the outlets with the further input; anda logic unit, which is configured so as to the plurality of outputs with the use of the plurality of inputs and of the further generated at the outset, and is designed in such a way that it uses the return path, in order to control the selected output so that it is equal to, such as the desired value is,characterized in thateach of the plurality of outputs an associated restriction limit value and the logic means comprises: a predictor which, for each of the outputs which are not the selected output, predicts a future value, and a comparator which the future value for each of said plurality of outputs with the restriction limit, which is associated with this output, compares, in order to determine whether any one of the outputs, which is not the selected output is, in this case is the associated restriction limit for this output is exceeded, to achieve or.
