cpmPlus History is a process historian and database for Collaborative Production Management (CPM) software that can be used to build software products and systems for utilities and manufacturing process industries, and integrate with other systems.

cpmPlus contains integrated software modules that all together provide highly scalable software platform. The applications vary from standalone embedded data logger for a piece of equipment up to large process historian system, or extended CPM solution that integrate the real-time performance measures with the current business context to support fast operational decision-making on the plant or utility level.

This document describes the new functionality of the cpmPlus History technology release 4.3 (2.0) compared to release 4.2 (1.0). Notice that the technical release number is 4.3, but the same technology package is also known with commercial version number 2.0.
