A computer program embodied in a non-transitory storage medium and comprising machine code, which, when downloaded to a memory of an administrative component of a computer network having a plurality of ports connected in one-to-one correspondence to respective production machines, with each of the connected production machines communicating via the computer network with a virtual user interface assigned to a respective production machine and with a higher-ranking facility, wherein the virtual user interfaces and the higher-ranking facility are arranged outside the production machines, and executed by the administrative component, causes the administrative component to
- monitor with a monitoring component designated ports of the computer network to detect whether an further production machine is connected,
- automatically activate a commissioning service, whenever the monitoring component detects that the further production machine is connected to any one of the designated ports, wherein, as a result of the activation, the commissioning service automatically at least
- assigns a virtual user interface to the further production machine,
- re-initializes an individual virtual computer network within the computer network, and
- connects the further production machine to the assigned virtual user interface via the re-initialized virtual computer network, thereby isolating communication between the further production machine and the assigned virtual user interface from other communications taking place via the computer network,
- maintain the isolated communication between the further production machine and the assigned virtual user interface until a release command is specified by an operator,
- activate, based on the specified release command, an integration service which, as a result of the activation, automatically
- re-initializes at least one virtual router,
- connects the re-initialized virtual router via the re-initialized virtual computer network with the further production machine, and
- configures the re-initialized virtual router so as to enable communication between the further production machine and the higher-ranking facility via the re-initialized virtual router.
