Description

The invention relates to automation and can be used in control systems of electronic parameters controlled by control computers (UVM), including digital hybrid and semiconductor integrated circuits.

A control device is known in which a switching matrix of switching elements enters, the signal inputs of which are connected to the corresponding software source 1 of voltage and current and the measuring unit, and the control outputs to the outputs of the corresponding triggers, single inputs of which are connected to the matching unit, and control and display unit with matching unit.

In accordance with the control program coming from the control room, using a switching matrix, program voltage sources, current and measuring unit are connected to the corresponding outputs of the controlled electronic circuit.

In order to eliminate spurious and emergency modes of the controlled electronic circuit that may occur when switching the switching elements of the switching matrix and increase their service life, the corresponding control program commands set to zero state

the software and the measuring unit and after that a number of new commands switch the contacts of the switching matrix. Therefore, to change the control modes of the electronic circuit, three types of commands are needed:

- resetting the software sources to the initial state;

- resetting the switching elements of the switching matrix (all contacts are open) and

- switching switching matrix.

However, in the known device there are a large number of individual commands in the control program of electronic circuits, which are not (It is necessary to set up the software sources, the measuring unit and simultaneously with the switching elements of the switching matrix, which increases the number of memory cells required dll hriyonp of the program of control and worsens effect1 | In 1ost of useSBA :: 1I in snstems control.

The aim of the invention is to reduce the number of teams.

For this purpose, the inputs of the OR circuits are connected to the matching unit, the second inputs are connected to the control unit and the output unit, and the outputs are connected to the input of the npcpl:
