Functional principle - LSM 3.5 SP3 Basic Online

It is possible to use the system as a gateway in the virtual network. The controller establishes a connection to the VN host server to do so. The VN host server forwards changed authorisations (programming requirement) and data from the LSM database to the controller. This means that complete, time-consuming loading of the database is no longer required; instead, the controller collects the provided data when an identification medium is detected (pull principle). The entire system is programmed via a single interface – the controller.

The VN host server regularly checks whether there are changes to the LSM database that are to be distributed via the gateway. It also does the reverse and checks whether there is information at the gateway that should be written to the database (see Check virtual network status).
