Safety-oriented control system for reliable triggering of an actuator

摘要

It is a safety-oriented control system (5, 5 ’, 5 ’ ’) for the safe control of at least one actuator is created, which comprises:a first safety-related sensor device (10, 20), at least one, of the first safety-related sensor device (10, 20) associated safety-related actuator (70, 72; 90, 92; 110, 112) and a safety-related data processing device (50, 60; 80; 100). The first safety-related sensor device (10, 20) has a network interface (18, 43), a memory device (12, 31), in which one of the first safety-related sensor device (10, 20) uniquely assigned to system information item is stored, and a control unit (14, 32), which is designed for this purpose, the first safety-related sensor device (10, 20) to cause the cyclically input data, each of which the unambiguous system information item and an additional information, which is in the fault-free operation with each transmission cycle in a predefined manner to the safety-related data processing device (50, 60; 80; 100) to transmit. The safety-related data processing device (50, 60; 80; 100) is designed for this purpose, the input data from the first safety-related sensor device (10, 20) to receive and process, in order to be able to detect additional information is transmitted with errors.
