Abstract

The invention relates to the field of automation and can be used to build control devices for discrete automata. The logic module contains information and control inputs, elements of IDN, NOT, delays, indications and a matching unit. The module works in two modes: Automatic and Adjustment. In Automatic mode, the control inputs are disconnected from the elements of the module. Then the value of the signal at the output of the module is determined by the values of the signals from external sensors to the information inputs of the module. In the Setup mode, the control inputs of the module are connected via microswitches to the inputs of the matching unit. Then, by supplying the corresponding signals to the control inputs of the module, you can set different values of the signals at the output of the module regardless of the signals at the information inputs of the module. The delay element allows the implementation of a delay in the switching on or off of the controlled executive circuit breaker. Connecting the output of the module to one of the information inputs provides the memory function. 1 hp f-ly, 2 ill. (Ls

Description

The invention relates to automation and can be used to build control devices for discrete automata.

The purpose of the invention is to expand the scope of application through the implementation of two modes of operation - Automatic and Adjustment.

Figure 1 presents the functional diagram of the logic module; 2 is a schematic diagram of a possible implementation of a matching unit.

The module contains groups of information inputs and 2, information input 3, control inputs 4 and 5, matching unit 6, elements OR 7-9, delay element 10, NOT element 11, display element 12, output 13.

The matching unit 6 comprises a diode I i, a resistor 15 and a microswitch 16.

The logic module operates in two modes - Automatic and Adjustment.

In the Automatic control mode, the inputs 4 and 5 of the module are disconnected from the elements of the module using external control buttons. Signals from the output of the element OR 7 are passed to the input of the element OR 8. Then, if there is a signal of a logical unit, xBt, at one input of the elements OR 7-9 at the output 13 of the module there will be a signal of logical zero, and if there is a logical zero at all inputs of the elements OR 7-9 module output 13 will be a logical unit. In Automatic mode, it is possible to stop the cycle at the desired cycle. For this, by pressing the external control button, a control unit 5 is supplied to the control input 5. Then, for any values of the signals at the inputs of the elements OR 7-9 at the output, the 13th module will have a logical zero signal.

in the Adjustment mode, the control input 5 of the module is disconnected from the control circuit, and a logical unit signal is supplied to the control input 4 of the module. Then at the output of the 13th module there will be a signal, logical zero.

To turn on the actuating element, control signal 5 is given a logic zero signal, which passes to the output of matching unit 6 and causes the appearance of a logical unit at output 13 of the module. Inputs

the element OR 9 is excluded. To eliminate the counter-inclusion of the executive elements of the machine in the Setup mode for all

The 5 inputs of the element OR 9 of the corresponding module are given signals of a logical unit. Delay elements 10 are used to implement an on or off delay.

10 actuator. If in the Setup mode the signals are not delayed, then the delay element 10 is turned off, and the output of the SHSh 8 element is connected directly to the input of the NOT element.

P. At this element; delay 10 is included between the output of the element SH7 and the input of the matching unit. To extend the temporal functions of the mo.

20 was blown by delaying different fronts of the output signal of the module and implementing the Memory function, you can use a second logic cell, similar to the one that is surrounded by a dashed line in FIG .. For realization, and the Memory output function of the second cell is connected to the information input 3 module .. Then, if the 13 module is connected to one

30 of the inputs of the second cell, then at short-term supply of a logical unit to the second / its input at output 13, the module is in a logical unit and will remain until reset, the memory is 35 ti. The reset is performed by applying a logical unit to any information or control inputs of the module,
