Abstract

Safety or protection system for a critical process has at least two safety or protection sub-systems. Each of the sub-systems has first and second means for monitoring respective parameters and providing respective signals representative of first and second parameters, the signals being provided to respective divisions of first signals. The first and second processing means process a different divisions of the signals to these outputs. First and second processing means are provided, and first and second communication means for communicating between the different protection sub-systems. Additionally, the means is provided for combining the first and second outputs of each of the said safety or protection sub-systems to effect a safety or protection function for said critical process.
