PARAMETERS to the control unit for the displacement of the ink ribbon and peSpuy control, and the two outputs of the buffer register are connected to the inputs of the display unit and the printing unit. The parameter relationship block contains a ratio adjustment knob and a successively connected co-node node, a combination adder and a digital analog converter, the inputs of the ratio node are connected to the switch outputs, the second input of the combination combiner, and the output of the digital-analog converter is a device output. Constructive implementation of the device shown in the drawing. FIG. 1 shows a diagram of the proposed device; in fig. 2 is a block diagram of the parameter deviation detection unit; in fig. 3 is a block diagram of the parameter ratio The block diagram consists of a multi-channel analog-digital converter 1, printing of its block 2, block 3 of deviating parameters, a device 4 for moving the red tape, block 5 of the display and block 6 for correlating the parameters. The block of parameter deviation detection unit 3 consists of a switch 7, a set of combination adders 8, analog digital converters 9, a rewritable control node 10 and a buffer register P. A multichannel analog-to-digital converter implements a sequential conversion of monitored parameters into a numerical equivalent with the output of the conversion results and the conversion number. being operated on the digital display option. The block of deviating parameters from the norm compares the code of the parameter values with the code set by the setting device, and in case of detecting a deviation of the parameter from the norm, distributes the disc signal to the control unit of the dye tape. , red, and current values - black. The input of the printing unit comes from: from a multichannel analog-to-digital converter - the code of the parameter number deviating from the norm; from the parameter detection unit deviating from the normal, its value code; from the control unit of the dye ribbon, a print enabled signal. The output of the printing unit is a digital registration form containing the number and value of the current parameters, as well as the deviation values of the parameters from the norm. The device works as follows. At each combination adder, the master sets the code corresponding to the parameter output beyond the maximum permissible norms. The start of the cycle is carried out from the printing unit in automatic or manual modes. A multi-channel converter in cyclic or address modes converts analog signals to a numerical equivalent. According to the measurement end signal generated by the analog-to-digital converter, the switch serially connects combinational adders to the output of the analog-to-digital converter to restart the output code. Writing the code into the adder is compared to the code of the established nominal values and in case of detection of parameters deviating from the norm, a sigal is transmitted from the adder to the rewriter control node, in which the output code of the adder is overwritten into the buffer register. After rewriting, the ink ribbon transfer unit generates a print resolution signal by which the printing unit digitally registers the number and value of both the current parameter values and the deviation values of the control parameters. The output code from the adder is fed to the inputs of digital-to-analog converters that convert the numerical equivalent to a unified analog-signal, the retention time of which is maintained until the next polling time of the monitored parameters. The output signals of digital-to-analog converters are designed to connect instrumentation and control local process control systems. In process control, by the ratio of two or several output parameters from the output of an analog digital digitizer, the value value of the first parameter is written to the ratio block via the switch, then the second parameter code is written. As a result of the comparison of codes, a code of the ratio of the values of the two parameters is formed. Then, the resulting code is compared with a predetermined predetermined value of the ratio coefficient code. As a result of the fusion, a differential code is formed, which, at the output of the digital analog converter, corresponds to an analog signal intended for use in process control systems according to the parameters. Thus, the device provides digital acquisition of additional information / formations, followed by its registration on the form, as well as receiving analog signals for control and use in local control systems for process parameters. The use of the device, in contrast to the known ones, makes it possible to obtain complete information in digital form about the number and value of both current parameters and the magnitude of deviations of parameters from the norm, its digital registration on paper form, as well as the possibility of including the device in multicomponent management systems. technological process both in individual parameters and in their agreement.
