Publish trends to the AVEVA Information Server

You can publish trends to the AVEVA Information Server. When you publish a trend, the trend report information is stored in special tables in the AVEVA Historian, and the file is copied to a folder on the AVEVA Information Server. When you publish a trend, AVEVA Information Server users can view the trend you published with only an Internet browser.

Published trends are of two types:

• Static. For a static trend report, AVEVA Information Server users see the same trend, but cannot alter the trend configuration in any way. They can, however, perform some basic navigation functions, like panning and zooming.

• On Demand. For an "on demand" report, AVEVA Information Server users see the same trend, but can fully manipulate the trend, including changing the configuration. However, any changes made to the original trend are not saved.

Published trend files contain the configuration information for the trend, but not the actual data values that are trended. For both types of reports, when the trend appears on the AVEVA Information Server, data is retrieved from the AVEVA Historian database and appears in the trend chart.

The AVEVA Information Server must be associated with the same AVEVA Historian as the trend you want to publish. If a trend references multiple AVEVA Historians, the AVEVA Information Server must be associated with at least one of the AVEVA Historians to publish.
