| Action at Edge | Result | Action | Result |
|---|---|---|---|
Create new folder with no tags | No change at Engine | Refresh Transmission | Folder will not be created at Engine |
| Add a tag to folder | No change at Engine | Refresh Transmission | Tag will be created under tag folder path at Engine |
| Delete a tag | Engine will mark tag as Bad_Stale | Refresh Transmission | No change at Engine |
Delete tag at Engine | Tag deleted | ||
Delete tag and add tag with the same name | No change at Engine | Refresh Transmission | Tag will be re-configured at Engine under tag folder path with any new properties |
Delete tag and create a folder which has the same name as the tag. Add a tag to this folder. | Engine will mark tag as Bad_Stale | Delete tag at Engine before a Transmission refresh is performed | New tag will be created under new tag folder path at Engine |
Refresh Transmission without deleting tag at Engine | Error similar to below logged, tag will not be deleted and no tag path folder will be created Error processing edit for tag path '[MQTT Engine]Edge Nodes/My MQTT Group/Edge Node 0964bf/PLC 1/New Tag/New Tag1': Bad_Unsupported("The target path '[MQTT Engine]Edge Nodes/My MQTT Group/Edge Node 0964bf/PLC 1/New Tag' cannot accept children tags.") | ||
| Delete tag and parent folder and add a tag with same name as the parent folder | Engine will mark tag as Bad_Stale | Refresh Transmission | Tag and folder will be re-configured at Engine |
Add UDT Definition and UDT Instance | No change at Engine | Refresh Transmission | Folder will be created named as the UDT Instance and UDT member tag will be created under tag folder at Engine |
Add new member tag to UDT Definition | No change at Engine | Refresh Transmission | New UDT member tag created under folder named as UDT Instance at Engine |
Delete member tag from UDT Definition | Engine will mark the tag as Bad_NotFound | Refresh Transmission | No change at Engine |
| Delete tag at Engine | Tag deleted | ||
Delete a member tag from a UDT Definition and add one with the same name in the same hierarchy position | Engine will mark the tag as Bad_NotFound | Refresh Transmission | UDT member tag will be updated with new properties under folder named as UDT Instance at Engine |
