MSP430F67791: DLMS\COSEM. An error in the ActionResponseNormal?

Hello Aleksej,

Let me loop in someone who is more knowledgeable about the DLMS library. In the meantime, are you using the EVM430-F6779 or custom hardware?

Hello, James,

I use apparently the EVM430-F6779, but the board is white and there is no display on it. 

Hello, James.

No. It is not related with that thread. 

Hello, James!

I received a response from the dlms association on this matter. See below:

You are right, it is necessary to indicate the CHOICE in Get-Data-Result.

The Green Book specifies this:

Action-Response-Normal ::= SEQUENCE
{
invoke-id-and-priority Invoke-Id-And-Priority,
single-response Action-Response-With-Optional-Data
}

Action-Response-With-Optional-Data ::= SEQUENCE
{
result Action-Result,
return-parameters Get-Data-Result OPTIONAL
}

Get-Data-Result ::= CHOICE
{
data [0] Data,
data-access-result [1] IMPLICIT Data-Access-Result
}

The correct answer would be this:

C70140000100 09109EDD35CB3B05D125800ED08B8D4DBA79

<ActionResponse>
  <ActionResponseNormal>
    <InvokeIdAndPriority Value="40" />
    <Result Value="Success" />
    <ReturnParameters>
      <Data>
        <OctetString Value="9EDD35CB3B05D125800ED08B8D4DBA79" />
      </Data>
    </ReturnParameters>
  </ActionResponseNormal>
</ActionResponse>

Please clarify this with TEXAS and Kalkitech.

best regards

How can this error be fixed on the stack?

Hello Aleksej,

Thank you for reaching out to the DLMS association, since they are much more knowledgeable about this topic than myself. However, when I saw the two zeros highlighted in red in your last post, it reminded me about an old thread that I had supported related to the "reply_to_hls" function. These issues appear to be very similar, so please take a look at the thread below.

As mentioned in the thread above, reach out to Chander G about obtaining the library with this bug corrected. For the reason that the DLMS library is no longer available online, please see my explanation in the following thread.

Hope this helps.

Regards,

James
