Note
For read / write cards you will have a meatball menu icon 
in the top right corner.
After changing the value, the card outline will briefly change color to indicate the results of the Control Change.
Note
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.

Note
In advanced settings, if the selected expire time has already passed when you click Add, it is automatically reset to one minute after the click.
The Control Change Manager uses the Advanced Settings to determine how it attempts to write the value and confirm it on the Asset.
| 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 |
When finished click on the Add button to initiate the value change to the Asset.
