When you click “Open Project” you open the tools for project configuration, or as we used to call, the Engineering tools.

The overview of the project configuration user interface is in Engineering Workspace.

All the project configuration, displays drawing, graphical images, scripts, tag definitions, external devices mapping, and so on, are saved in a single embedded SQL database. That file is encrypted for security and it should be opened and editing using the Project Engineering Tools.

The project configuration is saved is a file with extension TPROJ. Using the Publish procedure, described on Project Version Control, you can also create read-only versions of the project for runtime execution only, that will have the extension TRUN.

The system allows many projects to be opened at the same time. If you already have an open project, just select another project in the Project Selection list and open it. When a second instance of the same project is opened, it will open as read-only.

In order to enable concurrent-users you must have a project server licensed to multiple engineers. On the license tab, in the Engineering Group Box, you have the number of concurrent engineering users which can access the selected server or local computer.
