Abstract
A monitoring device is provided for a printer, especially a sheet-fed offset printer. The printer has 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. In the monitoring device, the signal states of the signal transmitters (G) of the printer units are fed to several slave computers (S), which are connected to each other via a monitoring bus (UB) and to a monitoring master (UM) connected upstream from the monitoring computer (UR). The actuators/drives (A) are connected to respective ones of the slaves (S) and can be switched off by the slaves in response to a command sent by the monitoring master (UM) via the monitoring bus (UB).
