摘要:
Systems and methods of configuring process control systems for operating process plants including multi-variable devices are disclosed herein. Multi-variable devices generate data associated with primary parameters and subsequent parameters. To facilitate configuration and use of subsequent parameters within process control systems, new device objects may be generated to represent the subsequent parameters. The new device objects may be generated as child device objects of parent device objects representing the multi-variable devices. Each child device object may also have a unique tag to identify the new device object within the process control system. The subsequent parameters of the multi-variable devices may thus be used within the process control system by reference to the tags of the corresponding child device objects.

Methods and apparatus to detect root causes of alarm patterns in process control systems are disclosed. An example method includes retrieving process control data generated in a process control system during a historical period of time. The process control data includes alarm data associated with alarms activated during the historical period of time. The example method also includes generating an alarm activation timeline for the historical period of time. The alarm activation timeline includes icons representative of the alarms to visually represent a temporal relationship of activation of the alarms, where one of the icons is representative of an alarm that is no longer active. The example method further includes storing the alarm activation timeline in a database.

摘要:
A selector shape may serve as the background to a configurable composite shape and may include one or more expressions that are evaluated to select between several composite shape definitions via links to the definition. Each selector shape includes an animation expression and a lookup table converter to select an identifier of the composite definition to be loaded and displayed. When the value of the animation expression changes, the value may be matched to the name of a new composite definition using the lookup table, and the new definition may be displayed. The previously-used composite definition may then be marked for removal by a caching system, and removed. These selector shapes also enable the same graphic element to be used in displays designed for different types of display devices, such as display devices having large display screens, standard computer screens and very small display screens.
