SCIOPTA Systems develops, sells, supports and maintains systems software for safety-critical embedded applications. This includes real-time operating systems, network software, file systems, software for interface bus systems, board support packages and other system software. SCIOPTA is a message based real-time operating system with many built-in safety functions and is therefore very well suited for software forming part of safety-related systems. SCIOPTA has been certified by TÜV to IEC61508 at Safety Integrity Level 3 (SIL3), EN50128 and ISO 26262. But SCIOPTA is more than just an RTOS. It is a new and modern approach to design embedded systems. The direct message passing method allows easy and time-saving design of robust and secure systems. Applications based on the SCIOPTA Method can cover small static SoC designs to large dynamic distributed systems.
