Hi Team,

I am testing command write functionality using the Rapid SCADA Test Client.

Environment:

* Rapid SCADA Server Version: 6.2.2.1
* Connected successfully to localhost
* User login successful

Test performed:

1. Selected “Send Command” (Option 17)
2. Channel Number: 104
3. Command Value: 1

Result:

* Test Client response: “Command sent successfully”

However, when I read the channel value afterward using “Get Current Data” (Option 6), the channel value remains 0 and the command does not appear to be executed by my driver.

Test Client Output:

* Channel: 104
* Command Value Sent: 1
* Response: Command sent successfully
* Current Channel Value after command: 0

Could you please guide me on the following points?

1. How should an external application/API send commands to this driver?
2. Which Rapid SCADA server API should be used for command write operations?
3. Does the driver need to implement a specific command handling interface or method to receive commands?
4. Is there any configuration required in Communicator, Server, or Webstation to enable command forwarding?
5. How can I verify whether the command reaches the driver but is not processed?

Any sample code or API documentation for writing commands from an external application would be greatly appreciated.

Regards,

Prabhu N
