ABSTRACT:
This invention relates to safety instrumented systems (“SIS”) for monitoring and controlling chemical and other industrial process field devices, and that are responsive to signals for the emergency shutdown of the process or system. The patent will significantly improve the reliability of communications within an emergency shutdown system, reduce unwanted trips, and adapt to process conditions by failing to a safe mode in dynamic conditions that are not considered by prior art logic solvers.
