The present invention relates to a control means for a printing machine, in particular a sheet-fed offset printing machine, having a plurality of units, such as feeders, printing units, varnishing and coating devices, deliverers, folding apparatus and the like, each unit being assigned a station having at least one computer and these stations being connected to one another via a first bus. It is intended to ensure that the switching processes which are to be carried out in the individual units of the printing machine at specific, predetermined angle positions can proceed exactly, even at the highest machine speeds. According to the present invention, for this purpose it is proposed that, in addition to the first bus, via which the stations exchange signals with one another, a second bus is provided, via which the individual stations may be fed with the angle position signals of a single-turn rotating angle encoder which is fitted on one unit of the printing machine. It is thus ensured that each station can carry out the switching processes which are a function of angle position in the associated unit.
