Abstract
A passenger transport system includes a central control unit for controlling system functions, field devices spatially distributed within the system, and a bus system transmitting data between the unit and the devices. The unit and/or the devices detect a current data transmission and the conclusion of the data transmission, and output different types of data telegrams that differ according to urgency. The unit and/or the devices output data telegrams only when no current data transmission is occurring and after a waiting period has elapsed since the conclusion of a previous data transmission. Each type of data telegram is assigned an individual waiting period on the basis of the respective urgency. Thus, a simple transmission prioritization is implemented during the data transmission, wherein each device can transmit data telegrams with different urgency and data telegrams of higher urgency are effectively transmitted with higher priority than data telegrams of lesser urgency.
