A method for checking a status of field devices of a building-based passenger transport system, the method comprising the steps of:
- transmitting a command block of a status telegram from a monitoring unit via a serial bus to a plurality of field devices connected to the serial bus;
- ones of the field devices addressed by the command block supplementing the status telegram wherein each of the addressed field devices receives the command block and determines a status end position in a data block of a status message adjoining the command block, each of the addressed field devices transmitting an associated status value to the monitoring unit via the serial bus when a status end position in the data block is reached, the status value encoding the status of the associated addressed field device;
- receiving the data block supplemented by the addressed field devices with the monitoring unit;
- evaluating the status values using the monitoring unit;
- and
- controlling operation of the passenger transport system with a central control unit that responds to the evaluated status values.
