FIELD: transport.
SUBSTANCE: invention relates to elevator installations control. The elevator installation contains bus unit (30), control unit (10), bus (9), the first and the second microprocessors (4, 5). During testing the bus unit (30) to control arbitrary signal sending by the first microprocessor (4) when status parameter is negative the control unit (10) transmits command to open breaker (31) to the second microprocessor (5) over bus (9). The breaker (31) disconnects data transmission wire (6) between RFID (3) system and the first microprocessor (4). The first microprocessor (4) does not accept identification code and generates status negative parameter. Thus, "disappearance" of RFID mark (1) is simulated.
EFFECT: reliable performance monitoring for the first microprocessor (4).
