The article analyzes the current regulatory framework for proof of safety, quality assurance, and confi rmation of the conformity of microprocessor-based railway automation and remote control systems in the EAEU. CENELEC standards are briefl y discussed. A brief overview is provided as regards measures to ensure the required level of safety of microprocessor-based railway automation and remote control systems from the point of view of quality management of development, safety management, and confi rmation of the proper functioning of microprocessor systems. The practice of confi rming the railway transport automated process control systems comply with standards in the form of a declaration of conformity per TR CU 003/2011 has been analyzed. It is concluded that there is a need to develop a regulatory framework to ensure regulated analysis and assessment of railway automation and remote control systems following the requirements of functional safety, as well as further development of standardization documents to regulate methods for assessing functional safety.

Abstract The article describes the main requirements of the software subsystems management development. Standard IEC 61508-3 provides an overview at all stages of the life cycle of all security systems, including E/E/PE of a security system from initial concept, design, and implementation to operation maintenance. In this paper we analyzed set out requirements for the drafting of a software architecture that is consistent with the hardware architecture while meeting specified requirements for software safety.

The progressing automation and robotization in the industrial plants as well as the increasing complexity of the control systems of integrated machines make it necessary to constantly improve the functional safety of machines through the correct validation of safety systems. Despite the validation process carried out, the potential software errors may reveal during the usage of the machine as hidden security breaches. The article presents examples of security breaches of real machine tools and attempts to implement solutions of automated mechanisms for detecting security problems. Another aspect of the article is the new approach for detecting hidden security breaches. Using the „digital twin” model of the machine, a program that generates a sequence of events for testing control systems, and the use of a virtual reality (visual verification of the safety programs), it is possible to maximize the functional safety functions of the machine.
