摘要： A method and a system for signal transmission between two computers is described, wherein one of the computers is fixedly mounted and the other computer is mounted in a rotational element, such as a plate cylinder of a printing machine. The transmission channel includes a rotational transformer. The rotational transformer utilized to transmit the signals is of single channel design. Data collisions resulting from the simultaneous transmission of messages are avoided through detection by the computers. Accordingly, both computers simultaneously transmit the signals present on the transmission channel during the transmission of a message and compare them with the transmitted signals. If an inequality is determined, the transmission procedure is aborted and restarted after a predetermined period of time.

摘要： A computer controlled sheet-fed offset printing machine is described which includes an Interpreter-program for obtaining an image of the signal-state of specified interfaces of the many interfaces that are needed for the operation of the computerized printing press. The Interpreter-program has access to a reserved region of memory for storing and manipulating, if desired, the image of the signal-state. Furthermore, the Interpreter-program has very limited and defined access to the inputs and resources used by the control programs used to operate the computerized printing press. This ensures that the control programs can execute in real-time unaffected by the execution of the Interpreter-program while data is acquired by the Interpreter-program while the computerized printing press is in operation. The Interpreter-program can execute diagnostic routines and provide data for detecting and correcting errors that are otherwise hard to localize in a complex system with complex software.

摘要： A bus system for a printing machine, in particular a sheet-fed offset printing machine, which includes a plurality of stations designed as computers, which are connected to one another via a bus. In the bus, it is intended that potential errors which occur at unforeseeable times can be detected, without it being necessary to intervene in the line system of the bus. According to the invention, this is achieved in that at least one of the stations has a bus coupler whose transmitting portion is designed for the purpose of outputting bus signals for the purpose of establishing a connection to the other stations, the value of at least one physical variable differing from the value of this variable provided in the line protocol. In the case of a bus designed as an optical waveguide, this is advantageously achieved by one station carrying out the attempt to establish a connection initially at a low transmitted power.

摘要： 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).
