Abstract

Circuit (SPSA) has a processing unit (VE) with an electrically erasable and electrically programmable read-only memory (EEPROM), a classification unit (KE) and an interface unit (EIF) for the read-only memory. The processing unit (VE) reads out from the read-only memory (EEPROM) instructions and/or data which have been automatically programmed in by a classification unit (KE) and an interface unit (EIF), as a function of input values (E) and/or internal values (ED, S) and/or output values (A) of the processing unit (VE). The processing unit may in this case take the form of a fuzzy controller or else a customary microprocessor. The advantage achieved hereby is, in particular, that the arrangement automatically adapts itself to the variance in structure (type diversity) and variance in time (ageing, wear) of a product and consequently the circuit has a wider range of applications and can be used optimally for a longer period of time.
