What system is designed to return an industrial process to a safe state after detecting a predetermined condition?

The Safety Instrumented System (SIS) is specifically designed to monitor and control industrial processes, ensuring that, upon detecting a specific hazardous condition, the system can execute predetermined actions to bring the process back to a safe state. This is crucial in environments where equipment failures or unexpected surges in operational parameters could pose significant risks to personnel, equipment, or the surrounding environment. The SIS typically includes hardware and software components that work together to implement safety measures integrated into critical processes, allowing for automated responses based on sensor input and established safety protocols.

In contrast, the other options serve different functions within industrial environments. Data Distribution Service (DDS) relates to data exchange between different applications, focusing on real-time performance rather than safety management. Information Sharing and Analysis Center (ISAC) deals with sharing cybersecurity information and intelligence, which is unrelated to physical process control. Facility Management Systems often handle the management of facility resources and operations but do not directly involve safety monitoring and intervention in industrial processes.
