Read Command Item
Sends a read command in control direction (client->server).
The item type has the following properties:
| Name | Description | ID | Flags |
|---|---|---|---|
| CA | Common address | 18700 | Persisted |
| IOA | Information object address | 18701 | Persisted |
On success, reads the current value of the information item on the server and should be reflected on the corresponding Information Item.
To trigger a read command:
- Configure the read command with the properties listed above;
- Set a new value on the item - not sent to server, only used for triggering a read command;
- On success; the value on the item is set and the value of the corresponding information item should be updated;
- On failure; the value on the item is not set - check log for more information.
Note! Under normal circumstances it should not be necessary to use the Read command - the server should update the client with new values automatically.
