Fusion of process performance monitoring with process equipment monitoring and control
First Claim
1. A process control system within a plant including:
- process equipment monitoring devices that collect equipment data;
process control monitoring devices that collect process control data;
process models adapted to perform process performance monitoring to generate process performance data; and
a computer system that implements a software routine that uses two or more of the equipment data, the process control data and the process performance data to perform a function within the plant.

Abstract
A process control system uses a data collection and distribution system and an asset utilization suite to collect data or information pertaining to the assets of a process plant from various sources or functional areas of the plant including, for example, the process control functional areas, the maintenance functional areas and the process performance monitoring functional areas. This data and information is manipulated in a coordinated manner by the data collection and distribution system and is redistributed to other applications where this it is used to perform overall better or more optimal control, maintenance and business activities. Information or data may be collected by maintenance functions pertaining to the health, variability, performance or utilization of a device, loop, unit, area, etc. and this information may then be sent to and displayed to a process operator or maintenance person to inform that person of a current or future problem. A user interface is provided that enables users to access and manipulate the expert engine to optimize plant operation or cause optimization of plant operation, to get information about the operation of the plant, etc. Furthermore, applications, such as work order generation applications may automatically generate work orders, parts or supplies orders, etc. based on events occurring within the plant.
