Overview of Global

AVEVA Global provides a simple and cost-effective administration and management system for Global projects, where data is distributed across a number of locations. To the engineer using the base product, it should be largely invisible that the project is distributed over many locations.

The first step is to configure a project as a Global project. There are a number of parts to this configuration:

1.

Specifying the locations.

2.

Selecting the database files needed at each location.

3.

Specifying when automatic data transfers can take place between locations.

Once this configuration has taken place, a Global daemon process will be started at each location; it is the network communications between these daemons that make sure the databases in the project are automatically kept up to date.

Note:

Before changing the project network e.g. when creating, modifying, or deleting locations, the Hub administrator should make sure the daemon is running, otherwise there will be a substantial delay on SAVEWORK in contacting the daemon.

After a Global project is set up, the user can use Data Access Control (DAC) to control users’ access to elements. For information about DACs in a Global project, refer to Data Access Control and Stamps in a Global Project.
