Requirements for functions, performance, and interface and environmental conditions for vital computers used in rail safety-related systems are established in this recommended practice. Vital computer functions are developed based on the technology of computer systems, communication, and functional safety as well as security considerations. A vital computer is composed with basic functional modules such as main process, input, output, and communication. This recommended practice can be applied to vital computers for onboard and wayside equipment in rail applications. Application systems which are developed based on vital computers are not covered, but safety-related conditions for application systems are proposed. The internal structure and the technical realization of the vital computer are not constrained in this recommended practice.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
