Documentation Control—11​.10 (k)

"(k) Use of appropriate controls over systems documentation including:

(1) Adequate controls over the distribution of, access to, and use of documentation for system operation and maintenance.

(2) Revision and change control procedures to maintain an audit trail that documents time-sequenced development and modification of systems documentation."

System Platform is configured with the Application Server IDE. This application provides a secure environment for developing and maintaining a system configuration. Galaxies deployed in regulated environments should employ OS User based or OS Group based security. All aspects of application development will then be controlled by a combination of Microsoft Windows and Galaxy security. See the AVEVA Historian online help for more information on how the Historian utilizes data quality information.

For more information on securing the IDE see "Working with Security" in the AVEVA Application Server online help.

The IDE also provides a revision history of Application Objects and symbols. A revision history includes records that track the life cycle of activities, such as object creation, check in/check out, deployment, and import/export. When objects or symbols are checked back in to the Galaxy after making changes, a dialog box prompts the user to enter comments about the changes. It is good policy to enforce mandatory check in comments in regulated environments.

A log of all changes and comments is available from the object properties menu. Following is an example log.
