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.

Control computer for a printing machine

A device is described for the state display for a printing machine, more specifically a sheet offset printing machine. The printing machine has a control, which is usually a computer, that communicates with several sensors and with a display device/computer. These sensors are located throughout the printing machine and can detect the position of certain elements of the machine. The invention extends the traditional printing machine state display so that it not only displays the simple state of the machine but also monitors previous states and can accomplish complex analysis of machine malfunctions. To accomplish this, the invention uses a storage device, which contains data on the representation and configuration of the machine and the sensors located in the printing machine. The control receives the data from the sensors and the storage device and sends graphical data to another computer that may process the information and present it to a display device.
