METHOD FOR DETECTING PROGRAM EXECUTION TIMES IN A DATA PROCESSING DEVICE

摘要

The invention relates to a method for detecting program execution times in a data processing device, for example a programmable controller. According to said method, the measurement of the execution times of a program or a sequence of programs takes place by the evaluation of the clock distributions of the data processing device in parallel with the processing of the actual program commands, using a processor that controls the data processing device. In a predetermined number of repeated measurements of an execution time interval, a minimum, maximum and/or an average value can be calculated during said measurement and can be stored in the processor for further evaluation.
