| 摘要 |
The invention relates to an elevator having a control unit (10), a bus (9), at least a first microprocessor (4, 5) and a second microprocessor (4, 5) that are allocated to a bus node (30) and that are connected to the control unit (10) via the bus (9). The control unit (10) transmits an instruction to the second microprocessor (4, 5) via the bus (9) to interrupt a signal transmission to the first microprocessor (4, 5) so that the first microprocessor (4, 5) sends a status message to the control unit (10). |
