According to a first aspect of the present invention, it may be provided a computer-implemented signal routing method for a building management system, hereinafter referred to as BMS, the BMS preferably being an access control system. The BMS may comprise a decision BMS-point, a plurality of signal-forwarding BMS-points, a plurality of enforcement BMS-points, and a plurality of action BMS-points, preferably each of the action BMS-points being associated with at least one of the plurality of enforcement BMS-points. It may be provided that each enforcement BMS-point is configured to cause operation of at least one action BMS-point, preferably the operation including unlocking an access point. The method may comprise obtaining, by the decision BMS-point, respective statuses of the signal-forwarding BMS-points. The method may further comprise determining, by the decision BMS-point, a target enforcement BMS-point configured to cause operation of a target action BMS-point. It may be provided that the method comprises selecting, by the decision BMS-point and based on the statuses of the signal-forwarding BMS-points and based on the target enforcement BMS-point, a signal route comprising at least a first signal-forwarding BMS-point, the signal route providing a signal path between the decision BMS-point and the target enforcement BMS-point. The method may further comprise sending, by the decision BMS-point, a first signal designated to the first signal-forwarding BMS-point of the signal route. It may be provided that the first signal comprises an instruction for the target enforcement BMS-point.

The invention is about a door system (100-103) with a computing unit (10, 10a, 10b) and a door device (40) for unlocking and/or opening a door,wherein the door device (40) includes an electronic memory (4010) for storing a digital configuration,wherein the door system (100-103) is designed to provide multiple different device modification procedures for the door device (40), which are configured to change the digital configuration of the door device (40), wherein each device modification procedure (200, 300, 400) of the multiple device modification procedures (200, 300, 400) includes changing the digital configuration of the door device (40),wherein the different device modification procedures differ in the type of digital configuration change,wherein the different device modification procedures are each designed such that a process step (201-212, 301, 305-310, 312, 401-412) is to be carried out manually by an user using at least one configuration device (30),wherein multiple process stages (2000-2005) are digitally predefined for the different device modification procedures, and the process stages (2000-2005) are the same in the different device modification procedures.

According to a first aspect of the present invention, it may be provided a digital token configured for use in a building management system (BMS), the token being storable on a user device and being presentable by a user using the user device to at least one BMS device out of a plurality of BMS devices for enabling the user device to interact with the at least one BMS device in accordance with a granted permission level, wherein the token includes: a user ID being associated with the user and/or the user device; a permission level indicator indicating a granted permission level out of a set of available permission levels, wherein the set of available permission levels is stored on each of the plurality of BMS devices, preferably each of the BMS devices being produced such as to include the available permission levels and respectively associated permission level indicators predetermined in the firmware before installation and/or commissioning of the plurality of BMS devices; an allocation information indicating the at least one BMS device out of the plurality of BMS devices for which the granted permission level is valid; a digital signature of at least the user ID, the permission level indicator and the allocation information.
