The invention relates to the field of automation, in particular to software control systems.

The purpose of the invention is to simplify (the device, as well as increase its reliability.

Figure 1 presents the structural diagram of the proposed device, figure 2 is a block diagram of a set of programs.

The device for program control contains a pulse generator 1, a time master unit 2, a block 3 of a program set, a decoder 4, first elements AND, register 5, second elements AND, execution units 6, position sensors 7 integrated into matrix 8, unit 9 comparison, counter 10 pulses, fixed memory unit 11.

The device works as follows.

From the output of the pulse generator to one of the inputs, the time of the master unit receives a continuous sequence of pulses with a frequency f j- | . To another input, the time of the master block receives a code that determines the division factor, the time of the master block. In the absence of a signal Setting ... zero, coming from the output of block 9 of comparison to the installation bus zero time of the master block, the latter generates pulses with frequency. The program dialing block — on each pulse coming from the time of master block 2 — forms: codes defining the division factor K; time of the master block, codes recorded in the i-th register and defining commands to the actuators, while writing the code from a block of a program set in the i-th register is produced by generator pulses arriving at the first inputs of the first elements AND, the address code, the first AND elements through which the code defining the instructions is recorded; i second AND elements, through which the outputs of the registers are connected to the inputs B of the comparison unit; i the words of the matrix of sensors that control the execution of commands defined by the code written from block 3 of the set of programs to the i-th register.

Decryption of the address i of the register, i of the first and second elements and i of the matrix word is performed by the decoder 4.

In the case of the inequality of these codes, block 9

Setting a zero on the installation bus to zero time of driver unit 2, thereby providing a stop mode for the program being processed, which is stored in block 3 of the program until the moment at which the specified codes are equal, i.e. until the corresponding sensors 7 of the matrix position are confirmed by execution by the executive units 6 of all the commands specified by block 3 of the program set.

The proposed device for software control has a simpler structural and fundamental

The program is implemented with a simple combination scheme.

In addition, combining the position sensors 7 into a matrix allows the r

Indeed, matrix 8, having 4 bits and 1 K lines, allows to process information from (K: 1) sensors 7 with (K + 1) szi channels, while with a common organization for information processing with (K-1)

The above method is especially effective with a large number of sensors.
