Soft antipassback
A status message 251 is issued here if one and the same badge enters the same room more than
once. Admission is still permitted!
Hard antipassback
A reader is always assigned to a room. This room may then only be entered once with the same ID.
If the same ID card is used again for access to this room, it will be rejected. Status 250 is output in
the data record during access control.
Here you can choose whether the reject is limited in time or whether Hard remains active.
In the case of Hard Active, access is not permitted again until another room ID has been accessed.
This corresponds to leaving the previous room.
