Abstract

The described methods and systems give users situational awareness regarding control loops in a process control system. The user can utilize the loop interface described herein to quickly understand how a given element (e.g., a device or function block) relates to other elements of the control loop. This enables the user to appreciate how modifying a parameter or device, for example, may impact control of the process. The user need not be intimately familiar with the logic associated with a control loop to understand the status of the control loop and its constituent elements. Further, in an embodiment, the user can easily correct certain statuses (e.g., unusual conditions) that arise with respect to the control loop.
