Safety techniques

Products used in safety applications have to exhibit a high degree of freedom from defects and faults. Depending on the area of application, the components or systems even have to be designed in such a way that the occurrence of one or more than one error does not lead to an overall loss of safety. For this reason all errors need to be identified without exception and at the same time be sufficiently manageable.



What follows is that error detection in principle relies on redundancy. This is defined as adding any kind of additional safety features or functions to a given system. In functional safety management, redundancy is used for the purpose of controlling, monitoring or plausibility checking.

There is a wide spectrum of concepts of redundancy. For example, a simple  hardware-based system can be run twice in a row with two different programs written by two different programmers. The results can be saved and compared with each other after the program sequence. This allows for discovering faulty code in good time.


Redundancy concepts are provided with simple or complex structures depending on the specific requirements and failure expectations. The individual availability determines a 2- or multiple channel structure.

Sporadic as well as permanent self-testing is a very established procedure for the control of available safety functions
