The accepted and proposed IEEE 1451 standards described in thischapter have been or are being developed to work together or separately,depending on system requirements. These standards should provide transducer-to-networkinteroperability and extended benefits to existing sensormanufacturers and network users. The potential to use the Internet in controlsystems will change the way networks are designed by engineers and used inorganizations. Chapter 13 expands the future potential and the visions that aredeveloping for networked smart sensors.References[1] Lee, K., “An Overview of the IEEE 1451—A Family of Proposed Smart Transducer InterfaceStandards,” Proc.
