Mounting the Device
After receiving the data, the host system evaluates it and reacts depending on the data received. For
booking data, the IF-60x0 system sends back a positive or negative booking response, for example.
Depending on the booking response, access is either permitted or denied.
The IF-60x0 system can also actuate relays or trigger an alarm if certain events occur. All booking data
and events of the connected terminals are stored in the memory of the
IF-57xx
device.
Offline mode
If there is no transfer of data between the
IF-57xx
device and the parent host system (e.g. the IF-60x0
system), the device will automatically switch to offline mode. There, it records all bookings and events
and autonomously makes decisions based on configured conditions.
In the event of a positive decision, a booking response and/or a signal for activating an output relay, for
example, are transmitted to the booking location. If the decision is negative, the reason for the booking
rejection is transmitted.
All bookings and status changes recorded in offline mode are stored in the device, together with a special
remark. The
IF-57xx
device transmits this data to the parent host system once an online connection has
been established again.
