Abstract

Disclosed herein are techniques for automatically distributing device identification amongst components of a process control loop in a process plant while the loop is communicatively disconnected from the plant's back-end environment or control room. A field device's identification is stored in a memory of a component of the loop (which may be the field device or a proxy) and is used for commissioning the field device. While the loop remains disconnected, the field device's identification is distributed to the memory of another component of the loop and used for commissioning a portion of the loop including the field device and the another component. Additional distribution to other components for commissioning other loop portions is possible. Distribution may be triggered by the completion of certain commissioning activities, the establishment of communicative connections between components, and/or other conditions. Other parameters and/or information descriptive of the field device may be similarly distributed.
