The closest analog with respect to the claimed technical solution shall be a device by the patent RU 2222865 (publ. 27.01.2004,, bul. №3).
Device known by the patent RU 2222865 includes the testing object, a set of software-controlled sources of input test signal, a set of gauges of signal parameters of the response of the computer. To control the outputs of the computer connected coded inputs programmable sources of input test signals, and to the code inputs, the computers are connected, the code outputs meters parameters of the response signals.
The main disadvantage of the device is the analogue of insufficient reliability of control due to unreliable contact object of the control, and also mistakes of the use of transitional devices when connecting the control object.
The aim of the claimed technical solution is:

3) increasing the efficiency of performance monitoring and fault diagnosis REA;
4) decrease of requirements to the personnel qualification.
This technical effect is achieved by a system containing object of the control, a set of software-controlled sources of input test signal, a set of gauges parameters of the response signals, computers, introduced interchangeable adapter, through which the outputs programmable sources of input test signal and inputs meters parameters of the response signals are connected to the respective inputs and outputs of the object of control, removable adapter introduced adapter ID, the inlets of which are connected to the outputs of additional channels of programmable sources of input test signal, and the outputs of which are connected to the inputs of the additional channels meters parameters of the response signals. In the testing object additionally there is the object ID of the control inputs, through a chain replacement adapter connected to additional outputs programmable sources of input test signal and outputs, through the appropriate chain replacement adapter connected to the inputs of additional channels meters parameters of the response signals.
Technical realisation of the declared system is explained in the drawing. The drawing shows a block diagram of the declared system of automated performance monitoring and fault diagnosis REA.
In the composition of the declared system (see the drawing) is the object of control 1 (for example, in the form of a functional site REA on the circuit Board), which via a plug adapter 2 is connected to a software-controlled sources 3 test input signals (including software-controlled power supply sources) and to the inputs of 4 meters parameters of the response signals. Inputs programmable sources 3 test input signal and outputs 4 meters parameters of the response signals are connected to the appropriate governing outputs and inputs computer 5. On removable adapter 2 installed adapter ID 6, the inlets of which are connected to the outputs of additional channels of programmable sources 3 test input signals, and output of which is connected to the inputs of additional channels 4 meters parameters of the response signals. The object of control 1 additionally there is the ID of the object of control 7, the inputs of which through the chain replacement adapter 2 connected to additional outputs programmable sources 3 test input signals and outputs, through the appropriate chain replacement adapter 2 is connected to the inputs of additional channels 4 meters parameters of the response signals.
In memory of the computer for 5 shall have been previously entered values for the identification codes of adaptors 2 (throughout the nomenclature used by adapters), as well as the identities of all types of objects of verification 1. The software modules identification established links between identification codes types of adaptors 2 and identification codes of the objects of control 1 for connection of which are appropriate adaptors 2.
Before the procedure, performance monitoring and fault diagnosis interchangeable adapter is installed and connected to sources 3 test input signals and sensors 4 parameters of the response signals. In interchangeable adapter 2 to install and connects the object of control 1. To verify the reliability of connection of removable adapter 2 to 3 sources of input test signal and measures 4 parameters of the response signals at the inputs of the ID of the adapter 6 served with relevant outputs programmable sources 3 test input signals combination of polling signal, measured with the help of additional channels meters parameters 4 the response signals identification signals and is formed on the basis of their identification code. The generated ID code is transmitted from the outputs of the respective channels meters parameters 4 the response signals in computer 5 obtained identification code is compared in computer 5 code type of a replacement adapter 2 to be used when controlling the object type control 1. The results of this comparison in the computer 5 produces a message about the reliability of the type and reliability of connection used by a replacement adapter 2, and on the readiness of the system to connect a control object 1 and initiating the process of performance monitoring and fault diagnosis.
To ensure control of the object type control 1 and reliability of its connection to removable adapter 2 (if available in the testing object 1 object identifier control 7) to the inputs of the object identifier control 7 served with relevant outputs programmable sources 3 test input signals combination of polling signal, measured with the help of additional channels meters parameters 4 the response signals identification signals and is formed on the basis of their identification code of the object of control 1.

In the computer memory 5 fixed combination test input signals that are detected facts of refusals. After the completion of the health check of the object of control 1 over all combinations of input test signal and fixing all detected faults claimed system is switched to the mode and fault diagnosis REA.
