PASSENGER TRANSPORT INSTALLATION, SERVICING METHOD AND SERVICING CONTROLLER

WO103081 - 20 - PCT/EP2016/081394 The passenger transport installation (1), e.g. an elevator or stairway, comprises at least one drive motor (11), conveying means (3, 4), at least one sensor (S1, ..., S9) and an installation controller (21), which is connected to at least one local bus node (231) via a status bus (22), which bus 5 node can receive status signals from an assigned sensor (S1) and transmit same to the installation controller (21) via the status bus (22), by means of which installation controller the passenger transport installation (1) can be controlled depending on the status signals received. According to the invention, a servicing controller (26; 26A, 26B) is provided, which, as a replacement for at least one of the sensors (S1), is connected or can be connected to the local 10 bus node (231), which is assigned to the replaced sensor (S1), or to a centralized bus node (230), the servicing controller (26; 26A, 26B) in particular being provided for delivering simulated status signals that correspond to the status signals of the replaced sensor (S1) in a state that is selectable by means of the servicing controller (26; 26A, 26B). 15 (Fig. 2)
