An elevator has a control unit, a bus, a first microprocessor and at least a second microprocessor, which microprocessors are associated with a bus junction and which are connected by the bus with the control unit. The control unit communicates an instruction by the bus to the second microprocessor to interrupt a signal transmission to the first microprocessor so that the first microprocessor transmits a status message to the control unit. |
