Add a topic

When you add a new topic for an I/O Server, a new row is added to the Topic table in the Runtime database.

Topic names must be unique for the I/O Server, not for the global system. You can have two topics with identical names, as long as they are on different I/O Servers.

To add a topic

1. In the Operations Control Management Console tree, expand a server group and then expand a server.

2. Expand Configuration Editor, expand System Configuration, and then expand Data Acquisition.

3. Expand the IDAS that contains the I/O Server.

4. Right-click the I/O Server, and then click New Topic. The New Topic wizard appears.

   

   Note: If you are configuring a topic for a classic IDAS (that is, an IDAS that existed before installing Historian 2017), you'll also see fields for setting the idle duration and processing interval.

5. Enter the configuration information for the new topic. For more information on these options, see Edit general information for a topic and Edit storage rules for a topic.

   You can set storage properties for a topic after you add it to the system.

6. Click Finish.
