A monitoring device for monitoring a passenger transport system includes at least one sensor, a control unit, a bus, and at least one bus node connected to the bus. The bus node has a microprocessor and an inspection unit for data exchange with the control unit. A first program module in the microprocessor detects a state change of the sensor that is connected to an input of the microprocessor via a transmission line and spontaneously transmits a corresponding state message to the control unit. A second program module in the inspection unit, after receiving an instruction from the control unit, transmits an activation signal to a coupling point in the bus node that simulates a state change of the sensor, the activation signal being superimposed on a sensor signal and/or being coupled into a power supply line connected to the sensor.
