Principles and methods of on-line testing for digital components and systems are analysed. The features of diagnostics for safety-critical NPP I&C systems are described. The paper zeroed in on component-based approach to safety-oriented on-line testing. Several methods, techniques and schemes for on-line testing of digital components of safety critical I&C systems are proposed. These methods are based on using of natural information redundancy and reduced checking of the components.
