? ! , a device, a non-selectable block [J Grammaple Sequence system 11 equipment of a printing press equipped with a state variable storage device, a synchronization section for sending out a rotation angle same signal, and an output device for sending out a control 11 command. The edict is publicly known (East German Patent No. 98041
No. Specification). The disadvantage of this sequence controller is that the program storage is designed for only one type of mark of a particular type. This requires replacing the 1 gram storage device each time, which incurs large refurbishment costs. For example, when attempting to operate on the last marked section, According to the type of printing part τfK3.The later printing part is the 2nd to 8th
This is necessary in the case of a printing section. (Problems to be Solved by the Invention) The purpose of the present invention is to increase the versatility of a printing press sequence control device.

The state of the machine is used as a process variable, and the operating commands are commands entered manually. place? An input device 11 connected to the pl unit 1 to 2 is used to indicate the state of the machine, for example the occurrence of double or slanted sheets M, the ejection of incorrectly inserted sheets into a special tray, the sheet Equipped with multiple input units for professional wrestling signals such as stacking of paper, or allowing staff to perform specific mechanical operations, such as ejecting 50 sheets of paper to a special paper ejection stand for printing start cutting, and removing paper from the paper feeder. It is configured as a capotan with an operation finger that can input morph cutting, etc. Process Shinta three prongs

[Let's do manual operation - The operation commands entered are the same as the machine cycle using conventional and well-known means! '11, so there will always be a single input signal. The output device 3 coupled to the start control device 6 comprises a plurality of outputs. 1. The output for sending out the 11 command is configured as an operating element for controlling a non-rotating angle synchronous machine operation or as an operating element for controlling a rotating angle synchronous machine operation.

The program storage device 4 for the operating sequence, which is connected to the start control device 6, comprises the following partial program storage devices according to the configuration of the processor: - a fixed-program addressable subprogram storage for the operation of the machine during normal operation; - deviations from the normal operation of the machine caused by the machine and/or by the personnel, e.g. Fixed program addressing subprogram storage for sequential operations when special υ1 outputs occur, such as heavy paper; Non-selective program addressing state variable storage for process variables and operation commands. Machinery All state variables of the above variants are stored in this memory. Control program memory with a fixed program for a processing unit - for the case of exchanging input and output data with respect to the memory. In the intermediate storage device for intermediate storage of data, the print section does not carry out the operations specified in the area (
You have to pull it. For this reason, processing unit 2 is synchronized with ff
Combined with 1l 5. In that case, it is preferable to express the time dependence in terms of the rotation angle of one rotation axis of the printing press. The synchronization unit consists of a signal distribution device (FVi) and a signal distribution device for transmitting the rotation angle increment. These devices are known.
Preselected degrees within one rotation - e.g. 11°; 2
