ABSTRACT:
A processing module is disclosed for capturing of analog input values, in particular for microprocessing systems and storage-programmable control systems. The control unit (40) comprises a program storage (41) and a read-write storage (42). The program storage is provided with its own storage region (1'-8') for each measurement input (1-8). The analog measurement region, coordinated to each measurement input, is programmed in the program storage and the kind of the analog measurement value is programmed in the program storage. The storage region (1'-8') is programmed by the user before the measurement event, whereby the semiconductor switches (11-28) can be correspondingly activated for each measurement. In case of a change of the kind of the analog measurement value, or in case of a change of the analog measurement region, only the storage contents (1'-8') of the program storage (41) are to be changed according to the new measurement values. A hardware modification of the measurement inputs is not required in this case.
