FIELD: information technology.
SUBSTANCE: method involves checking data for control objects (CO) of automated control systems (ACS) in the administrative part for conformity with data types of a composite database, information packets are generated, the CO is queried on readiness to receive information over a local area network (LAN); in the client part of the ACS, a query is sent for user authentication, readiness acknowledgement is sent over the LAN to the administrative part, in the administrative part, packet priorities are allocated for their sending over the LAN, and packets are sent over the LAN to the client part, where suitability of the packet for loading is verified; if the packet is not suitable, an error acknowledgement is sent to the administrative part, where packets are re-generated and then sent to the CO.
EFFECT: reliable transmission of data between computer systems with different database structures in automated control systems, cutting on time for exchanging information, realisation of the system in low-speed communication channel conditions.
