<p>A monitoring device is described for a printer, especially a sheet-fed offset printer, with a controller that records the signals of signal transmitters in the individual units of the printer, through which command signals for actuators/drives connected to the control can be generated as a function of the signal state, and a monitoring computer that additionally records the signal states of the signal transmitters and causes the switching off of actuators/drives. The task of the following invention is to modify such a monitoring device so that a device is obtained that permits error-proof and, especially, differentiated actions during malfunctions. A variant according to the invention consists of the fact that the signal states of the signal transmitters (G) are fed to several slaves (S) designed as computers, which are connected to each other via a bus (UB) and to a monitoring master (UM) connected upstream from a monitoring computer (UR), and that the actuators/drives A are connected to one of the slaves (S) and can be switched off with a command sent by the monitoring master (UM) via bus (UB).</p> |
