After centrally turning on the power from the control panel of the system, the microcontroller 40 is started in the calculator module 4 in the interface unit, which performs testing and initial settings in accordance with the contents of the ROM 38. The RAM 39 is loaded and the programs contained in the ATA DISK 35 (HDD) are executed and on the ISA 34 bus the following operations are performed:

- the system adapter is installed and prepared for use, the backup computer switching module 6 and the exchange controllers 15-18 with external systems in the multiplex channel 2 module and relay exchange module 3;

- hardware-software control of the state of “one's own” and the host computer in module 6 is set using the signals of the address decoder 52 and data transmission through the bus amplifier 53, the necessary values are recorded in the watchdog timer registers 57 and 58, the bits that enable the signals are set in the control register 56 interruptions of the microcontroller 40 from the interrupt register 55 in the event of a “failure” of the host computer;

- the channels used are configured in the MCO 2 module, for which, through the adapter 19, programmable control register registers 21 are set to a certain state, sequences of commands for the mode are sent to the buffer RAM 11-14 of each channel

data reception, for data transfer mode, determines the size and type of RAM buffer.

Next, communication is established via the Ethernet local area network with other devices of the ship control system through the switch module 5 and network controllers 42, 43, and

coordination of the interface of the parallel bus PCI 44 with the inter-instrument serial interface of the Ethernet network.

The operation of the interface device is controlled using commands received in the microcontroller 40 from the control panel of the system via a local area network. Having received the appropriate commands, the interface device carries out exchange sessions with the supporting systems of the ship. Through the adapter 19, the control circuit 21 of the MCO 2 module receives a signal to receive information from the supporting systems, after which the module channels under the control of the controllers 15-18 automatically execute a sequence of commands from the buffer RAM 11-14 and information is exchanged via the serial serial interface via transceivers 7- 10. At the end of the communication session, the received information is stored in the buffer RAM 11-14 and is read by the microcontroller 40 through the multiplexer 20 and the adapter 19. It is processed and transmitted to other devices of the ship control system using network controllers 42, 43 and the local area network switch module 5.

In accordance with the time diagram of the operation of the control system, the microcontroller 40 provides relay control signals to the actuators and the joint weapon system, and also monitors their implementation by analyzing the response signals. The microcontroller 40 performs the generation and reception of relay signals using the relay exchange module 3, transmitting information to the FPGA 26 via the ISA 34 bus through the buffer stages 27 and the bus amplifier 28. To generate output signals to the ship supporting systems, the microcontroller 40 installs triggers in the FPGA 26 that control electronic keys 25 and electromechanical relays 24, after which the result is controlled by the feedback circuits from the UER 24 to the FPGA 26. If the result is negative, then the signal is issued from the paired circuit. Input signals from external systems are fed to the optoelectronic isolation elements 23, where they are converted to TTL logic levels and are interrogated similarly to feedback signals from UER 24.

To ensure the trouble-free operation of the interface device, redundancy has been introduced, that is, there are two independent identical interface circuits - left 1.1 (computer1) and right 1.2 (computer2) with individual power supply, while, when the control system is operating, one of them is switched on in the operating mode (main) , and the other is in reserve and is ready in the event of a failure of the main device to continue its work in the specified mode.

The backup switching module 6 provides a high speed for switching the backup computer to the main mode in the event of a failure. For this, the microcontroller 40 via the ISA 34 bus through the address decoder 52 and bus amplifier 53 with a constant time interval writes a certain value to the watchdog registers 57 and 58, from which continuous subtraction. In the case of “freezing” of the microcontroller 40, the timer overflows and a failure signal is received from the control register 56 to the paired circuit, through which the backup computer switches and continues to execute the mode. From the coupled loop, the failure signal enters the interrupt register 55, which generates an interrupt on the ISA 34 bus.

The functioning of the duplicated local area network "Ethernet" is provided in the interface device by the switch modules 5 (LAN1 and LAN2), each of which controls the data flows in its network and allows you to simultaneously send information messages between any pair of subscribers in the ship control system.

The switch module supports full duplex mode, in which data is transmitted and received at the same time, while the data transfer speed is doubled.
