A system, method, and an apparatus relating to data collection regarding valve movement over a period of time in order to determine the effects of stiction on the valve. With data collection done over a period of time, it is possible to remove dependency on a high speed method of data collection. The evaluation of the valve movement includes consideration of a manipulated variable (MV) for diagnosis, or detection, of stiction of the valve.

Method for detection of diagnosing control valve stiction

A configuration system for a process control system configured to perform process control. The configuration system includes, not limited to, a) a definition module, which is stored in a memory, for a part of an industrial plant based on design data. The definition module includes, not limited to, a-1) a control logic definition file configured to define a control logic for the part, and a-2) a data definition file configured to define data relating to the defined control logic.

Process control system and configuration system

A configuration system, for a process control system configured to perform process control, the configuration system includes, not limited to, a) an editor configured to perform one of generate and update one of a definition module and an application module, wherein a set of the definition module and the application module comprises control logic and design data for a part of an industrial plant. The editor includes, not limited to, a-1) a definition module generator configured to generate or update one of a definition module control logic and an application module control logic based on the definition module design data. The editor is implemented by one or more processors.
