Sequential program control system

To provide for uniform timing of program control cycles in which different control cycles have different cycling time, the control cycles being connected in parallel to a program control arrangement, timing elements are connected in the respective signal paths controlling the respective cycles and adding time increments to the signals coursing in the respective paths between the input and the output to at least approximate the coursing time of all signal paths to a uniform time duration; if the coursing time periods of the signals through the respective paths do not differ substantially, a fixed delay can be added to all the coursing times so that the percentage variation between the coursing time of different cycles, considering the overall time, is small.
