About this task

If you have set the Migrate Trend Configuration and Migrate Totalization Configuration fields to True when configuring your N1 Integration object, then any Trends or Totalizations attached to objects in the Metasys N1 Network are migrated as extensions to the corresponding Metasys system object. Otherwise, you can use the Extension wizard to add extensions manually.


  • If you want to mimic Point History using Trend extensions in the NIEs, be aware that each extension you add in the Metasys system counts as an object.
  • Before adding Trend extensions for Point Histories, consider whether Point Histories are needed in the migrated Metasys system.


  1. If the Extensions Wizard is not already open, navigate to and right-click the object or device to which you want to add an extension.
  2. Select Show Extensions. The Extension wizard appears (Figure 1).

  3. Click New next to an extension type and follow the prompts from the Extension Wizard. See Adding Trend Extensions to Objects, Adding Totalization Extensions to Objects, or Adding Alarm Extensions to Objects for information about each type of extension.
