Summary:In the paper, some discussion of the implementation of a fault-tolerant hardware platform is presented. The discussion is focused on the control applications with less severe integrity requirements (SIL1) and where the intelligent system reconfiguration is preferred (instead of the redundancy) in the case of failures. To build a dependable control system, all aspects of the implementation must be considered and integrated into the development from the beginning. A network of simple monitoring modules should be integrated into the system to detect and react to faults as soon as possible. To streamline the implementation, not only the hardware, but also the appropriate system software, must be constructed to hide the particularities of the low-level matters from the control application.
