A knitting machine, in particular a warp knitting machine with a central control apparatus (120) containing a computer with an input device (122) for the establishing of the characteristic data of the knitted article (20) to be produced and with a central control unit (124) which is connected over a line (126) with individual drives (16, 28, 33, 35, 63a, 63b, 63c, 63d) for aggregates (15, 22, 32 34, 44a, 44b, 44c, 44d) of the knitting machine. The knitting machine has a main drive (16) for at least one needle bar of a row of needles and a central control unit (120) with an input device (122) to establish the characteristics of the knitwear to be produced. In order to improve the control, each drive (16, 28, 33, 35, 63a, 63b, 63c, 63d) of individual components (15, 22, 32, 34, 44a, 44b, 44c, 44d) has an individual intelligent control unit (163, 283 33.sub.3, 35.sub.3, 63a.sub.3, 63c.sub.3, 63d.sub.3) to assume and process the relevant program module of the control device (120). The drives are interconnected and synchronized via a shared reference value pulse generator line (130), in which one drive (16) is the main drive and an appropriate pulse generator (16.sub.4) is the reference value pulse generator.
Knitting machine, in particular a warp knitting machine with a central control apparatus containing a computer with an input device for the establishing of the characteristic data of the knitted article to be produced and with a central control unit which is connected over a line with individual drives for aggregates of the knitting machine, in which each drive has an individual, intelligent control unit for the take-over and working-out of an appertaining program module from the central control apparatus as well as, a timer for each aggregate for the determination of the working position of the aggregate, characterized in that the drive of one aggregate is constructed as a main drive and the appertaining, timer is constructed as a desired-value timer, wherein the latter is connected over a desired-value timer line directly with the individual control units of all the aggregates, wherein the remaining timers are joined as auxiliary timers in each case with the appertaining drive constructed as an auxiliary drive, wherein a pattern program input on the central control apparatus is workable on the individual control units independently from the central control unit of the central control apparatus.
