of the data is calculated for future use and extrapolated and the chronological development is transmitted to the second central data processor 9 when a corresponding threshold value is exceeded the second central data processor 9 thus has a statement with respect to the further development of the data and therefore can more precisely evaluate the functioning of the printing press on the basis of the transmitted chronological development the second central data processor 9 can automatically set up a service and or can order a component part group and or can set a service date for example in another preferred embodiment the first central data processor 1 evaluates the data to the effect whether service is necessary at the printing press for this purpose corresponding comparison values are deposited in the first memory 4 if the result of the evaluation is that a service is necessary corresponding information is transmitted to the second central data processor 2 at the program point 50 the chronological development of the data is preferably calculated in the first central data processor 1 which is provided with a number of data operating parameters and or adjustment values of the printing press 7 and which therefore can calculate the chronological development in a fast manner as a result thereof it is not necessary to transmit the data required for calculating the chronological development to the second central data processor 9 in a further advantageous embodiment the first central data processor 1 on the basis of the comparison at program point 30 determines whether a component of the printing press is defective if the result of the comparison is that a component.
