AVEVA™ Enterprise Licensing Topologies

A single node topology involves a computer with Plant SCADA, License Manager, and License Server installed. In this configuration, the communication between the server components, License Server, and License Manager is local. Internet access is required to connect to the Activation Server.

Typically a single node topology would be used to test a project on a development workstation. It can also be used for training or evaluation purposes.

The licensing components can be installed on separate computers as long as there is reliable network connectivity between them. This type of topology is suitable for systems where you need to manage licenses for multiple installations of Plant SCADA across a distributed runtime system.

In the following example:

• The Enterprise License Manager components are installed on a computer with Internet access to the Activation Server. The interface runs locally in a web browser.

• The Enterprise License Server components are installed on two separate computers that are acting as a redundant pair.

• The Plant SCADA runtime computers each require network access to the License Servers.

  

This type of topology allows you to manage multiple License Servers for a runtime system from a single License Manager browser interface.

License Server redundancy is highly recommended when centralizing your licenses. It is available at no additional cost. A paired set of License Servers keeps licenses, reservations and the status of licenses synchronized to help maintain stability for the runtime system.

If you use clustering to manage a system that is physically distributed across multiple sites, it is recommended that you have a pair of redundant license servers at each location.

For information and procedures about implementing redundancy, see the topic Working With License Server Redundancy in the AVEVA Enterprise Licensing documentation in AVEVA™ Help.

This topology is required if an internet connection is not available. For example, a firewall or other constraints may exist between the License Manager components and the Activation Server.

In this scenario, you need to set up a separate computer with Internet access to the License Activation Web Page and Activation Server and then complete the activation process in "offline" mode. For more information, see the topic Activating Licenses in Offline Mode in the AVEVA Enterprise Licensing documentation in AVEVA™ Help.
