  • the current ratings are 40 parallel to their connection to the selection module AB each as a threshold level 44 on a threshold value module Given SB.
  • the selection module AB can now e.g. be designed as Minimum value module, which is based on the current ratings 40 selects the minimum and this as its output signal gives the summer 42 as an input signal.
  • the summer 42 links the output of the selection module AB with a constant K to a sum that is simultaneously on the inputs of all threshold value blocks SB is switched. Because that too threshold levels associated with the respective threshold value modules 44 are different in their values, the input signal is the same for all threshold value blocks SB, only those deliver Threshold value modules an output signal not equal to zero as commands Z1, Z2, Z3, ... Z8, which is about the constant K raised input signal the value of the respective associated Threshold value exceeds.
  • the previously described variant of the selection module AB as a minimum value module is particularly advantageous when determining components to be connected to the technical system used. For determining components to be switched off The selection module AB is preferred in the technical system pronounced as a maximum value block. This ensures that - if the evaluation is similar to that described in FIG. 2 is carried out - those components as in the next Components to be switched off are determined which have the greatest value as current ratings 40.
