More than ever, running your plant safely and productively requires the right technologies and experience. With increasingly stringent regulations and standards-based best practices, safety instrumented systems perform a critical role in providing safer, more reliable process operations. Research shows that over 92% of all faults in SIS applications occur in field instruments and control elements; therefore, it is critical to consider the entire safety instrumented function (SIF) – from sensor, to logic solver, to final control element - as a complete entity. As a smart solution, DeltaV SIS continuously monitors the abilities of  sensors, logic solvers, and final control elements to perform on demand and diagnoses faults before they cause spurious trips. This approach increases process availability and reduces lifecycle costs.
