Hello,

I’m working on a Java project using the Gurux DLMS library to certify DLMS/COSEM communication with the IM300 meter from WASION.
I’ve managed to establish the physical connection to the meter (via serial/TCP), but I’m facing issues during the authentication process. Specifically, I’m encountering errors in the second step of the communication, during the AARQ request (Application Association Request), where the meter should reply with an AARE (Association Response).

Below are the authentication parameters provided by the manufacturer to assist with configuration:

in android project profile buffer in billing profile
if i select from date and to date the buffer details is not coming

Unable to read attribute =3 (1.0.94.91.0.255) IC=7 for Indian Metering, while I'm able to read attribute 3 for other Profile generic class

I'm using python lib.

Code:
inst_obj = GXDLMSProfileGeneric("1.0.94.91.0.255")
read_inst_profile = b''.join(secure_client.read(inst_obj, 3))
print("\n→ Read inst buffer:", read_inst_profile.hex())
ser.write(read_inst_profile)

I have made a configuration on "Register Activation" class but attribute index data 3 is not visible on GxDLMS Director. Instead of data it is showing following system Generic list as

 System.Collections.Generic.List'1[System.Collections.Generic.
KeyValue2[System.Byte[].System.Byte[]]]

 System.Collections.Generic.List'1[System.Collections.Generic.
KeyValue2[System.Byte[].System.Byte[]]] 

Tariff log of all attribute index are (rest attribute index data is visible on GxDLMSDirector screen) as 1

Hi,

Can someone explain in simple terms how reading load profile data works on an L+G E560 meter?
