Description

The invention relates to computer technology and can be used in the technological process of manufacturing a computer console, which is used to set the operating modes and indicate the state of the computer when troubleshooting the maintenance mode. The purpose of the invention is to increase the performance of the device. The drawing shows a structural diagram of the proposed device for the visual control of an electronic computer console. The device contains a generator of 1 pulses, a 2-bit counter, a 3-byte counter, a 4-word counter, a register 5, multiplexers 6 and 7, the element OR 8, the element 9 and the element NOT 10. In addition, the drawing shows a block diagram of the control panel 11 A computer comprising an input switch 12, a group of indicator registers 13, a group of information tumbler registers 14, a group of encoders 15, a multiplexer 16 and a control tumbler register 17. The device operates as follows. The control principle is based on the fact that the device writes the state of the information registers 14 of the group and the state of the control register 1 of the controlled computer console to its indication registers 13 of the group for visual control, and the state of the information registers 14 of the group of the controlled console 1 1 is written to the high bytes of the corresponding indicator registers 13 of the group of the control panel 11 being recorded. Recording the state of the control register 17 of the control panel 11 (the outputs of setting the modes of the first group) to the indication Registers 13 are made through the first multiplexer 6, and the recording of the state of the information registers 14 of the group (the outputs of setting the modes of the second group) through the second multiplex 452 sor 7. The information outputs of the counters 2, 3 and 4 control the recording of the information bits from the output of the element OR 8 to the corresponding bit of one of the indicator registers 13 of the group of the controlled console 11. The change in the state of counters 2, 3 and 4 is carried out according to the signals generated by the pulse generator 1. The 3 byte counter information outputs control the connection to the inputs of the OR element of the first or second multiplexers 6 and 7 using. elements Y and 10 With a single state of all information outputs of counter 3 (the address of the last byte of the register) the second multiplexer 7 is connected to the input of the element OR 8 with a single signal from the output of element 9. When the counter status of 2 bits changes, the contents of one are recorded from the information registers of the 14th group of the control panel 11 ,. the number of which is determined by the state of the counter 4 registers, into the high byte of one of the indicator registers 13 of the group of the controlled console 11, the number of which is also determined by the state of the counter 4 words. If the state of at least one of the information outputs of the 3 byte counter is different from one, the second multiplexer 7 is closed for transmitting information with a zero signal from the output of the AND 9 element. At this time, the first multiplexer 6 is opened for transmitting information (with a single signal from the output of the HE 10 element ) and recording occurs to the indicator registers 13 of the group of the control panel 11 of the control register 17. Thus, when monitoring the control panel 11, there are no manual operations to directly check the display registers and information signals, since their verification is carried out simultaneously with the control of controls.
