Hi Mikko,

Initially, I have connect meter using high-level security. Then set the secret from Association 0.0.40.0.5.255. Now I am trying to connect a meter with updated secret but not able to connect.

Can you please check the following logs and provide an update.

Let me know if you require more information about the same.

Hi,

Hi,

Make connection to the meter without authentication. Read Association view. There is something like:
Management Frame Counter in data objects. Copy Logican Name (OBIS code) of that data object.

Select "Secured connections" -tab from device settings.
Paste Logical name to "Frame Counter LN".
Now Frame Counter is read and updated automatically.

BR,
Mikko

Hi Mikko,

Hi Mikko,

The frame counter is updated properly in both MR and US associations.

But after that object list is not downloaded and got the same error as below:
Gurux.DLMS.GXDLMSException: Access Error: Device reports a undefined object.
at GXDLMSDirector.GXDLMSDevice.InitializeConnection()
at GXDLMSDirector.MainForm.Connect(Object sender, GXAsyncWork work, Object[] parameters)

Hi,

Hi,

Is the exception coming in the same place? Check that your keys are correct and the Invocation counter is increased.
