The Assets page is the first page you will see when you log into the Kelvin UI. You can also go there by clicking on the Asset option in the left sidebar.
Here you have a list of all Assets registered in Kelvin. From here you can see the Assets and associated information.

Groups
Initially Data Streams are grouped into two groups.
- Setpoints : Data Streams that are set as read / write when creating the Connector.
- Datastreams : Data Streams that are set as read only when creating the Connector.
You can also add custom groups and move any of your Data Streams into your custom groups.
Manage Groups
You can manage the groups and define where you want to show each Data Stream.
Note
If you do not assign a Data Stream to a group, it will be shown in the default group Data Streams.
To manage your groups, click on the settings icon in the top right corner.
You will then see your group management window.
You can filter the Data Streams that are shown on the list in this group management section.
Note
This does not change how the Data Streams are displayed in the Dashboard itself.
You can drag and drop an Data Streams to reorganize the order of the Data Streams.
Or use the move icon.
Add Custom Group
The default groups are mandatory and can not be removed.
Note
If there are no Data Streams listed in a default group or all Data Streams are hidden, then the Group will not be shown in the Dashboard.
You can also add a new custom groups.
Simply click on the Add Group button.
A side bar will open up.
Give the new group a name.
You can also immediately populate it with your wanted Data Streams.
And then Click the Add Group button.
And you can see the new group with your preselected Data Streams.
Closing the Group sidebar you can see it now in your Manual Controls Dashboard.
Data Stream Cards
Read / Write Card
For the read / write Data Streams you will see the Data Stream values and have the ability to write new values or see the Control History.
If a Control Change fails, then the card will also show a red error mark to alert you that there is a problem.
You can see the issues by looking at the history.
Read Only Card
For the read-only Data Streams you will only see the Data Stream values and when it was last received.
Change Values
For read-write Data Streams you will also see information about the last Control Change that has been performed and the status of that action. You can also send a new value to the Asset / Data Stream pair by clicking on the three dot button in the top right corner of the Data Stream card and select New Value.
To change a Read/Write data value, click on the hamburger menu in the card containing the data value of interest and then click on the New Value option. A popup will appear where you can change the value and if necessary you can change the default control change parameters as well in advanced settings (such as how many times to retry writing to the asset when there is a failure or timeout).
There are also some advanced settings which will override the default control change settings.
Unless instructed these settings normally do not need to be changed from the defaults.
The Control Change manager directly sends new values to the asset and waits for confirmation from the regular readings by the Connection. If discrepancies are found between the new values and the regular readings, the manager will repeatedly attempt synchronization until consistency is achieved or a failure is determined, based on the advanced settings.
| Title | Description |
|---|---|
| Expiration Date | This is the final date when all attempts to change the value is abandoned |
| Retry | How many times to retry writing the new value before giving up |
| Timeout | How long to wait and monitor the Connection values for synchronization before trying to write to the asset again |
Control Change History
To see the history of Control Changes for a particular Asset / Data Stream pair, click on the hamburger menu in the card containing the data value of interest.
And then click on the Check History option. A side bar will appear on the right showing you the information of the full history of Control Changes.
