Pivot object model
The pivot object model is based on 61850 semantic.
...
| Attribute | Description | Expected values | Mandatory |

| send_iv_time | time delay before infos are sent as invalid (0 = deactivated) | default = 0 | No |
| tsiv | specifies what to do with a time stamp marked as 'invalid' | remove, process, default = remove remove: the time stamp will be removed from the information object process: the time stamp will be processed on regular basis and additionally marked as 'not synchronized' | No |
