Overview

The Related Values Processing Framework is being developed to help the integration of process control data historian systems. This is done by providing support for the conversion, computation and distribution of data point values between these systems.

The software is written in Java. All libraries needed to use this software are available under an open source license.

The support for commercial data historian systems WILL NOT be included in this project. Instead, documented interfaces for the integration of such support will be provided. The framework does include a data historian capable enough to support all of its functions.

Since this is a framework for a very technical subject, it is expected that its users will be integrators with expert level knowledge and technical skills.

Context

The focus of this project is on the circulation and processing of manufacturing points data. By point data, we mean a reference to a point definition, a timestamp, a state and a value. The point definition specifies where the data comes from, where is is stored, what it contains, what effect it may have on other points data, etc. The timestamp indicates when the contained value was generated. The state qualifies the value. The value can be a count, a floating point value, a text string, or anything acceptable at the point of storage.

The points data will usually come from some SCADA (Supervisory Control And Data Acquisition) or DCS (Distributed Control System) implementations. It is assumed that time-critical responses have already been provided by lower level systems.

Informations

Technical informations on this project is available thru links on the left of this page.

Under the 'Documents' heading, the components document illustrates the main components of the framework; then the metadata documents the information structure supporting these components.

The metadata is further described by comments in its DTD.
