The paper presents a fault-tolerant system designed for the pellet production process control in metallurgical plants. The system is based on a RT-ARCH (Real time ARCHitecture), an architecture of which software tools are used in development and run-time application phases for the specific equipments used in process control in metallurgical plants. The software tools make the 16/32-bit equipments work together in an integrated fault-tolerant system, capable of meeting the general and specific requirements of the application. NONSTOP-32 proves fault-tolerance by high redundancy, by data and code replication (via a high speed communication connection) on the different nodes of a distributed system.
