Quick development of technologies together with the tendency that "brain" replaces "iron" are causing need to use new technologies in devices intendent for safety related applications. This applies also for distributed systems since, quite often, a bunch of cables is replaced with a pair of wires. Nowadays, there are available several commercial distributed systems designed for safety related applications in machinery. In distributed systems there are specific fault modes, which are typical of the technology. There are also some risk reducing methods, which are typical of distributed systems. Actually, in communication systems the safety depends very much on software and mathematical calculations, which help to estimate a certain level of confidence. When validating a single channel communication system one has to concentrate on the typical fault modes, but one must not forget the basic fault modes, such as open circuit.
