Edit summary tag properties

You can edit the properties for a summary tag. The general procedure is similar to the procedure for adding a summary tag.

In case of a change that would result in a tag name collision with tags defined on the same lower-tier Historian going to the same next-tier Historian, the change is discarded and an error message appears. Collisions with replication tags configured from other lower-tier historians are overwritten without an error message from the next-tier Historian. Be careful not to create or modify a replicated tag on a lower-tier Historian to have the same tagname that already exists on a next-tier Historian. The system does not prevent you from having a replicated tag on a next-tier Historian receiving data from multiple lower-tier historians. However, when you retrieve data for that replicated tag on the next-tier Historian using the tag name, an incorrect blend of data from the two (or more) data sources is returned. Collisions of non-replication tags on the next-tier Historian fail at connection time and are logged to the ArchestrA Logger.

When you change the replication server node name or replication group, the replication tag is removed from the old group and added to the new group. Replication tags that are changed to a new replication server or group do not have their changes logged to the new server or group until changes are committed.

To edit properties for a summary tag

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

2. Expand Configuration Editor, expand System Configuration, expand Replication, then expand Replication Servers.

3. Expand the replication server, expand the Analog Summary Replication folder or State Summary Replication folder, and then expand the replication group containing the summary tag.

4. Double-click the summary tag you want to edit properties for. The Properties dialog box appears.

   

5. In the Replication Server list, click the replication server to edit.

6. In the Replication Group list, click the replication group.

7. In the Source Tag box, type the name of the tag that provides the source data for the summary tag. For more information on finding a tag, see Find source tags.

8. In the Replicated Tag box, type the name of the summary tag.

   Note: The Current Editor option is reserved for future use.

9. Click OK.
