You can select a source tag or replicated tag from the Tag Picker to add the corresponding replicated tag or source tag to the active trend chart.

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.

      Add_ReplicatedTag

      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:

  • You are connected to the IndustrialSQL Server 9.0.2

  • 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.

    The above 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.
