The quantity of software in equipment used for critical process control and safety instrumented systems is growing. This is due to a strong trend toward using flexible safety PLCs instead of relays or DCSs in safety instrumented systems. Safety PLCs are microcomputer-based controllers that are designed for high safety and high availability applications. Safety PLCs offer application flexibility, self-diagnostics, communication interfaces to other plant automation systems, automated application tools that help prevent human error [1] and a level of reliability and safety not
