DeviceNet is a new standard for an industrial, device-level network for connecting a wide variety of industrial instruments, actuators, and control computers. Over 300 manufacturers make products that are certified by ODVA to work with this standard. It reduces overall installation costs by minimizing wiring and improves measurement accuracies by eliminating transmitted analog signals. This talk will give an overview of the DeviceNet standard as applied to vacuum systems. It will cover typical costs, performance issues, design parameters, and some of the products available. It will include a study on the use of DeviceNet on the Spatial Filter Vacuum System in the National Ignition Facility (NIF) at the Lawrence Livermore National Laboratory (LLNL.).
