Smart Engineering Manager's Web interface provides access to a collection of sites present on the server you log into. Each site is a logical container for its related plants. Plants can contain none or several associated applications. Navigating starts from selecting a site, then a plant, and then selecting from the associated application. Typing in the Sites page Search box and the Choose Plant page is another way to navigate through the interface.
The diagram below is an example of a configuration that might be present on a server you log into.
