Controller communica-
tion with LSM
The SREL3 ADV system can also be used as a gateway for the virtual
network, no matter whether a relay contact is used or not. Any identification
medium which is logged onto one of up to three readers is updated. In
doing so, a difference must be made between network-dependent and
network-independent functions.
– Loading time budgets: Users are able to re-upload their time
budgets at any time without the network.
– Automatic blacklist distribution: IDs which have already been
flagged for blocking in the controller are also distributed in the
virtual network without a network connection.
When the network connection is re-established, the controller
transmits information which was collected during the outage:
– Feedback signals from blacklist broadcasts: Locking devices
which have received authorisation changes for transponders emit
a feedback signal. This feedback signal is transmitted to the
controller via the virtual network.
– Battery warnings: Locking devices which have low batteries
transmit a battery warning to the controller via the identification
media in the virtual network.
– Physical access lists: The smart card physical access list are read
and saved by the controller independently of the network.
If there is a network connection, other virtual network functions are
available on the gateway:
– Issuing of individual authorisations: When an identification
medium has logged on, the controller retrieves the latest
authorisation information for the transponder concerned from the
VN host server via the network. The authorisation changes are
updated on the transponder via the reader if necessary.
– Configuration changes: The controller retrieves configuration
changes to identification media, such as a time group change,
from the VN host server.
– Issuing of individual blacklist IDs: Up to two IDs to be blocked can
also be added to selected identification media in the virtual
network. To do so, the controller retrieves the IDs to be blocked
from the VN host server when such an identification medium logs
on.
The controller does not communicate directly with the database. A
distinction must be made with communication between the controller
and the database:
