You're confusing the use case. If course you can already look up the data and get alerts, and every modern plant already does. But getting hands on data when you're at the plant isn't just helpful for repairs or inspections, it's helpful for lots of things including debugging problems, helping new employees learn about the plant and "map" the processes to the physical layout of the pipes. Nowadays people lug around papers or tablets, so this would just be an extension of that.
