4.3 Access control with B-Client AC30
4.3.1 Operating states
The access manager allows the following operating states:
• Online
• Fast online
• Offline
• Autonomous
4.3.1.1 Online
The “Online” operating mode is recommended if the arising data records must be
permanently available in the host computer.
After a booking, the access manager carries out the programmed checks and writes
the test result as an error ID into the registration record. The registration record is
transferred to the host computer. After that, the access manager expects a logical
booking response from the host computer. With this response, the access manager is
informed by the host whether or not the booking is authorized.
If the access manager does not receive a logical booking response from the host
computer, it will change to offline mode and decide itself, according to the pro-
grammed verifications, if the booking is authorized or not. As soon as the host com-
puter is accessible again, the access manager changes back to online mode. All data
records stored in the meantime in Offline mode are transmitted to the host com-
puter.
4.3.1.2 Fast online
In contrast to online mode, a query to the host computer takes only place if the inter-
nal booking response is negative. Individual access points can be set to Fast Online.
4.3.1.3 Offline
After a booking has been made, the access manager carries out the programmed
checks and decides immediately by way of an internal booking response whether
or not the booking is authorized. If the host computer is available, registration data
records of authorized and unauthorized bookings (depending on the set parameters)
will be transferred immediately. Otherwise, the registration records will be stored in
the access manager. As soon as the host computer is available, all data records stored
since the last transmission are transferred to the host computer.
4.3.1.4 Autonomous
After a booking has been made, the access manager carries out the programmed
checks and decides immediately by way of an internal booking response whether
or not the booking is authorized. Registration data records of authorized or unautho-
rized bookings are stored in the access manager, depending on the set parameters.
If the host computer is available, any existing error and alarm records will be trans-
mitted to the host computer.
The stored registration data records are transmitted to the host computer with a spe-
cial data record after request. Once transferred to the host, the data records will be
deleted in the access manager.
