A machine control system for a machine or plant controls a plurality of functions within an operating cycle. The start signals and stop signals for releasing and ending respectively the function can be preselected with respect to their mutual relative time slot by means of a data processor (computer) with a display screen. To this end, the functions of the machine or plant are listed in parallel lines on the display screen. Each of the functions can be represented in a graphic quantifying the duration of the function by inputting display screen signals with the limits, which correspond to the times of connection (start limit) and disconnection (stop limit) of the respective function. After starting up the operating cycle, the display screen signals are scanned by a switching signal, which advances in time in the direction from the start limit to the stop limit. The connection signal and disconnection signal, respectively are supplied to the machine control system, when the switching signal coincides with a display screen signal. The graphic of each function can be a bar diagram with bars, which are each associated to the functions, and the start and end of which mark the times of connection and disconnection of the respective function on a time axis parallel to the bars. |
