Apparatuses (1) for mapping devices (21-29) to representations (31-39) of the devices (21-29) in models comprise displays (11) for displaying representations (31-39), memories (12) for storing triggering information defining triggering procedures for triggering the devices (21-29), inputs (16) for receiving identifying information comprising identifiers from devices (21-29) that have been triggered, and processors (14) for linking the identifiers and the representations (31-39) at the hand of the triggering procedures. The commissioning of devices (21-29) is done faster and more user-friendly. The triggering procedures may define the devices (21-29) to be triggered in a sequence. The processor (14) can then link the identifiers and the representations (31-39) via the sequence. Alternatively the triggering procedures may define unique codes to be allocated to the representations (31-39) and to be provided to the devices (21-29), with the identifying information further comprising the codes. The processor (14) can then link the identifiers and the representations (31-39) via the codes.
