The invention relates to a machine controller for a machine or installation which controls a plurality of functions within an operating cycle. The start signals and end signals for initiating or terminating the functions can be preselected with regard to their mutually temporal relative status using a data processing system (computer) having a monitor. To this end, the functions of the machine or installation are listed in parallel lines on the monitor. Each of the functions can be represented in a graph, said graph quantifying the duration of the function, by inputting monitor signals with the limits which correspond to the instances of the activation (activation limit) and deactivation (deactivation limit) of the respective function. After starting the operating cycle, the monitor signals are read by a switching signal which temporally progresses from the activation limit toward the deactivation limit. The activation or deactivation signal of the relevant function is transmitted to the machine controller when the switching signal coincides with a monitor signal. The graph of each function can be a bar diagram with bars which are each assigned to one of the functions and whose beginning and end, on a time axis parallel to the bars, mark the instances of the activation and deactivation of the respective function. |
