Synthesis, analysis and selection procedure of architectural variants of the processing node as a part of the instrumentation and control system (I&CS) for safety-related applications is presented. Required levels of reliability and functional safety (FS) can be achieved in case of using this procedure at the design stage. I&CS processing node for safety-related applications is considered as an autonomous, unified computing and control node which consist of processing modules with ability to reconfiguration. The FS indexes assessment procedure, which takes into account the criticality degree of I&CS architectural elements and processed functions is specified.
