Abstract

One cycle of a programmable controller includes reading-in (E) the input signals, processing (B) the input signals, whereby inter alia the output signals are calculated, and outputting (A) the output signals. The time one cycle takes can be shortened by processing (B) the input signals at least in part simultaneously with the outputting (A) of the output signals of the preceding cycle and with the reading-in (E) of the input signals of the subsequent cycle.
