FIELD: communication.SUBSTANCE: group of inventions relates to operation of a control network. Disclosed is a method of operating a control network with a single connection between first and second control computer backup host computer through network, to which many functionally important technical data processing devices. Information-technical connection between computers and devices is provided by a state request command, wherein for beginning of control network is checked communication connection between both computers. For a positive test result, first computer is assigned a master function, and for a negative test result, both computers are connected to device itself in established order. When connecting a predetermined number of devices to one of two computers, computer takes a leading function, and other computer - backup function when placed below a predetermined number of devices connected to each of two computers, a signal is generated which indicates a fault condition management network.EFFECT: technical result is improved safety and operational reliability of control network.8 cl, 1 dwg |
