Exception Response: Instance ID 0.0.40.0.0.255

Sir,

I have changed the DLMS-Version from 0 to 6 as you suggested. Now the error regarding the version number is removed in the test-report. All the other values are still the same except for <UInt8 Value="00" /> is now replaced by <UInt8 Value="06" /> as mentioned above.

What does it mean by 'Get 5 invalid' ?

I understood that in my previous question, 'Get 5' represents an Attribute 5.
Here is the Request-Response Hex values of Association Logical Name : Attribute 05.

I also noticed a note states, "//Protocol version must be 100001". Is the error regarding to the version again? Although I have changed the version number,

settings->base.dlmsVersionNumber = 6;

Also, by mistake I mentioned class ID-1 in my very first question, but its actually a Class ID-15.
