Description

The invention relates to automation and computer technology and can be used as a control device for various types of electronic equipment, in particular, technological equipment for the production of integrated circuits. A device for cyclic 1-gram control of a manipulator is known, comprising an encoder, a shift register block, a decoder, a trigger block, an output driver, AND and OR circuits fl. However, this device solves software control problems, is complex in the organization and has a limited scope, since it does not allow to implement branched programs with prioritized external conditions. Closest to the proposed Do technical entity is a multichannel device containing a pulse count, the input of which is connected to the second input of the device, and on each channel a switch, the first input of which is connected to the corresponding output of the counter, the second inputs to the first inputs of the device, and the outputs to the third input of the switch of the next channel, and the decoder, the outputs of which are connected to the outputs of the device. The device analyzes the state of the external conditions applied to the second inputs of the switch, and, depending on their values, organizes sequential or non-consecutive sweeping over of its states in accordance with the specified algorithm 21. The disadvantages of this device are: limits on sequential and non-consecutive change state and possible violation of the sequence of change of state due to different times of switching of switches and decoders, which limits the scope of application of the device.

The unbranch circuit is an extension of the functional possibilities of multichannel gadgetry for program control.

The specified target is obtained by the fact that a clocking unit is entered into the device, a register and a trigger in each channel, the first input of which is connected to the switch code of this channel, the second input to the first output of the clocking unit, and the output to the first input of the fourframe

this channel, the second input connected to the outputs of the register, the first input of which is connected to the output of the pulse counter, and the second input - to the first output of the clock unit, the second and third outputs connected to the first and second inputs of the pulse counter, the third input of which is connected to the second input of the device and the outputs of the decoders - with the outputs of the device, the input of the clocking unit is connected to the third input of the device.

FIG. 1 is a block diagram of a multi-channel software control device.

The multi-channel device for program control contains a pulse counter 1, a clocking unit 2, a register 3 and, in each channel, a switch 4, a trigger 5 and a desch (| racr 6.

The device works as follows.

External conditions arrive at the second inputs of the switches 4. The pulse from the first output of the clocking unit 2 overwrites the information from the outputs of the pulse counter 1 to the register 3, and the information from the outputs of the switches 4 to the triggers 5. Depending on the values of the external conditions, the decoders 6 output the output effects, corresponding to the fulfillment or non-fulfillment of external conditions. These actions are used both to control external devices and to form the addresses of the transitions and the control signal transfer, which are fed to the second and third inputs of the device, respectively.

The pulses from the BTqjoro of the clock unit 2 are used to record information from the second input of the device to the pulse counter 1, and the pulses d of the third output are used for sequential

wn

increase the content of the counter 1 pulses per unit.

The operation of the clock unit is determined by the state of the third input of the device. If there is a signal on this input

transmitting the control, the clocking unit 2 generates pulses on its first and second outputs, in the absence of the first and third outputs.

With this, the necessary bending is achieved: the bone of a multi-channel device for program control. In the absence of the need for an inconsistent change of states, j.e. In the absence of a control transmission signal, the device automatically transitions from one serial state to another. Providing the transmission control signal and the transition address will cause the device to enter the state corresponding to this address.

The introduction of new elements — a register, a clocking block, and into each trigger channel — eliminates the limitations of sequential and non-sequential state changes and eliminates the possibility of state sequence imbalance, thus expanding the functionality of the device and its scope.
