PUTTING MACHINES WITH VIRTUAL COMPONENTS INTO OPERATION IN ISOLATED MODE WITHOUT DISTRIBUTING IP-ADDRESSES Russian patent published in 2019 - IPC G06F1/00 

FIELD: computer equipment.

SUBSTANCE: invention relates to a method of operating a computer network. Computer network (1) has multiple connections (2), to some of which are connected production machines (=PM) (4), which communicate via computer network (1), respectively, with at least one associated virtual interface (=vHMI) (6) operator and higher device (7) outside PM (4). Monitoring component (11) controls predetermined connections (2) for connection of additional PM (4'). If connection of additional PM (4'), then service (14) of commissioning is automatically activated, which automatically relates at least with additional PM (4') vHMI (6'), inside computer network (1) re-establishes own virtual computer network (16) and additional PM (4') with associated vHMI (6') connects through the newly installed virtual computer network (16). That is how communication of additional PM (4') with associated vHMI (6'), isolated from other communications. Isolated communication is maintained until a resolution command (F) is input.

EFFECT: wider range of tools for the same purpose.
