Add a source tag to a trend

You can select a source tag or replicated tag from the Tag Picker to add to the active trend chart. For more information about the different components of the Tag Picker, see Learn about the Tag Picker in AVEVA Historian Client.

To add a source tag or replicated tag

1. Select a tag in the Tag Picker.

2. If the selected tag is a source tag, do the following:

   • In the Tags pane, right-click the selected tag, point to Add - replicated tag, and then click the tag that you want to add to the trend chart.

     

     The corresponding replicated tag is added to the active trend chart.

3. If the selected tag is a replicated tag, do the following:

   • In the Tags pane, right-click the selected tag, and then click Add - source tag.

The corresponding source tag is added to the active trend chart.

The Add command is not available if:

• Multiple tags are selected in the Tag Picker.

• A normal tag that is neither a source tag nor a replicated tag is selected in the Tag Picker.

  Note: You cannot execute the Add command if a source tag is deleted but its replication configuration still exists in the Historian.

The replicated tags are not listed in the context menu if:

• The replicated tags are not committed in the Historian.

• The replication schedule is removed from the Historian. For example, you are connected to a Historian 10.0 server and you create a tag called ‘MyTag’. ‘MyTag’ is replicated as a simple tag called ‘MyServer.MyTag’. When you execute the Add - replicated tag command, the ‘MyServer.MyTag’ tag is shown. When you execute the Add - source tag command, the ‘MyTag’ tag is shown. At this instance, if the replication link between ‘MyTag’ and ‘MyServer.MyTag’ is removed and if you execute the Add - replicated tag command, the ‘MyServer.MyTag’ tag is not shown in the list of replicated tags.

  However, if you execute the Add source tag command, the ‘MyTag’ tag is shown as ‘MyTag’. If ‘MyServer.MyTag’ is the only replicated tag, ‘MyTag’ is considered as a normal tag.

  This scenario holds true if the entire replication schedule is removed in the Historian. If only one replication is removed, the list shows the remaining replicated tags.
