Abstract :
This paper describes hybrid-redundant design of monitoring systems with proprietary industrial-control computer boards. Input channels use three-mode redundancy, host controllers two-mode redundancy and output channels use warm redundancy. Experiments and analysis of system reliability by the Markov model indicate that the reliability of normal operation for 5 years is above 0.9.
