Ensuring the functional safety of cyber-physical systems is a prerequisite for their implementation in areas in which reliable and predictable behavior of nodes of distributed cyberphysical control systems is a critical requirement. In the literature from the beginning of the 90s of the last century, within the framework of the theory of risk management, an approach to ensuring the functional safety of subject-centric systems is discussed. The conceptual basis of this approach is the provision on the inevitability of the presence of latent defects of different nature in complex technical systems, the activation conditions of which cannot be predicted. This implies the need to create barriers to the conversion of danger into an incident. The approach proposed in this paper to constructing a system of structural models based on the apparatus of conjugation schemes and truth tables of functional components should be considered from the perspective of information support for the formation of barriers. The basis of the approach to constructing structural models that allow performing a scenario analysis of the functional safety indicators of the nodes of cyber-physical systems is the apparatus of conjugation schemes and truth tables. It is shown that the proposed approach allows one to obtain models corresponding to Failure Tree Analysis, Root Cause Analysis, as well as a set of models obtained as part of the concept of profiles as particular solutions.
