摘要
Safety system of an elevator installation, with a control unit, a bus node, a safety element and a bus, which enables a communication between the control unit and the bus node. The bus node includes a first switching arrangement, which on digital presetting by the control unit acts on the safety element by a first analog signal. The bus node additionally includes a second switching arrangement which derives an analog signal from the safety element and makes digital feedback information available to the control unit by way of the bus.
