Overview

You can open only one system project at a time in an instance of the Topology Manager.

Data of objects that you edit by using the Topology Manager is automatically persisted in the Control Expert repository.

Hotfix Availability

To open, a system project requires the hotfixes that were installed on the computer at the time of its creation plus, any additional hotfixes that are installed on the computer on which you open it.

Thereafter, you can reopen the system project only on computers on which all these hotfixes are installed; otherwise, a dialog box opens, which indicates the hotfixes that are missing.

You need to install these hotfixes to be able to open the system project.

NOTE: To see which hotfixes are installed on a computer, open the About dialog box and click Technical Information.

Opening a System Project

To open a system project, proceed as follows.

Step

Action

1

Open the Start Page.

Result: The system projects that exist in the Control Expert repository of the system server to which you are connected are displayed in the Projects section.

2

Double-click a system project or select it and click Open .

Result: The software:

  • Closes the Start Page .

  • Opens the Default Physical View window of the system project and related panes.

  • Displays the identifier of the system project in the title bar of the Topology Manager.

NOTE: If the system project is password-protected, you must enter the password when prompted. Otherwise, you cannot open it.
NOTE: If a system project is already open, a dialog box is displayed. You need to confirm closing the open system project first.

Closing a System Project

You cannot close a system project unless you:

  • Open another system project in the same Topology Manager instance.

  • Connect to another system server.

  • Close Control Expert.

You need to confirm closing the system project that is open.

NOTE: You can close a system project even if it is locked.

Recovered System Projects

In case the software is not able to read the metadata of existing system projects (for example, their identifier) from the Control Expert repository, the next time the system server is started, the system projects are recovered and remain functional. Only their original properties are lost and the system project identifier is replaced with Recovered_ID where ID is a randomly generated string to maintain identifier uniqueness.

NOTE: If you have an up-to-date backup of the database, you can restore it to recover the properties.
