Gurux.DLMS

Hello, i tried to read Data object via GXDMLSDirector and it was okay. But when i tried to read it with .NET library it was exception "Exception response. "Service not allowed"-exception. Operation not possible".

GXDLMSData _data = new GXDLMSData("0.0.96.1.0.255");
_сlient.Read(_data, 2);

I did not read association, so i think is there missed parameters in GXDLMSData instance that i need specify?

Hi,

Have you established the connection for the meter or do you try to read the values right away? Have you updated the connection settings for the correct ones?

Try to read the value with the client example first.

I belive it will help you to get started.

BR,
Mikko

I'm sorry for not answering for a long time. I tried to run the client you specified, but the same exception occurred. In the code below, the connection was successfully established, but when trying to read the association, it immediately throws an exception.

public void ReadAll(string outputFile)
{
try
{
InitializeConnection(); // OK
if (GetAssociationView(outputFile)) // "Service not allowed"-exception.
{
GetScalersAndUnits();
GetProfileGenericColumns();
}
GetReadOut();
GetProfileGenerics();
if (outputFile != null)
{
try
{
Client.Objects.Save(outputFile, new GXXmlWriterSettings() { UseMeterTime = true, IgnoreDefaultValues = false });
}
catch (Exception)
{
//It's OK if this fails.
}
}
}
finally
{
Close();
}
}

There is log from console:

As you can see in the screenshot in the first message, the association was successfully read when first connected via GXDLMSDirector. I can't understand why it's not being read through the library.
