Hi, this is Juan From colombia, for the last days i`ve been working with the landis+gyr e 650 Model:ZMD402 & the CU-E22.
I`m gonna talk you about what i wanna achieve, and maybe you could help me with that.
Ok, from the last days i've been trying to connec the landis from the CU to python, i already know which port i have to use and all the security information.
I try with wrapper and HDLC but i dont manage to make it work.
Usually the device open the tcp and arrq, after that he makes the request from tx-AARQ with the information bytes.

We tried to follow your description about the pre-established connection:

As we understand it, in this mode the meter should continuously send data to the client, and the client should just listen without establishing the connection itself.

A few things are unclear:

HI any one with connecting experience of GENUS SUGAM 3P4W bi directional with DLMS??. can guide me??

Hello Gurux Team,

We are currently facing an issue while reading meter data using the Gurux DLMS libraries.

In the field, some meters display six-digit KWH values (for example, 987654.32). However, when we fetch the value from the meter using GXDLMSDirector, we receive only five digits (for example, 87654.32).

The meter display shows the correct six-digit value, but the response appears to be skipping the first digit in the reading.

Please let us know if you require any additional logs, OBIS codes, or sample responses from our side to investigate this issue.

---> Summary
==============
- When using **OnePassDiffieHellman** signing mode in GXDLMSDirector GUI, the application throws a "Object reference not set to an instance of an object" when trying to read objects after successful connection. Additionally, the **Server keys** section in the "Secured Connections" tab cannot be expanded or scrolled to configure server certificates.

It would be possible to increase serial baudrate to higher values, greater than 115200?

Hi,

I would like to ask whether the conformance tests are aligned with the latest Yellow Book or with any version of the Yellow Book. I have also launched the simulation model of an electric power meter and disabled all tests except the HDLC tests, but it still fails several of them. The results show: Test #1 failed, Test #2 failed, Test #4 failed, Test #10 failed, Test #14 failed, Test #15 failed, Test #16 failed, Test #17 failed, Test #18 failed, and Test #19 failed.

Hello Mikko,

any news about GetRequestWithList Translator error?

Unfortunately can't comment old post, so decided to create new one.

Hi,

I'm trying to connect to wasion meter. the security is using HighGMAC. and the response is "Connection is permanently rejected. No common AcseVersion"
I try many combination on client, logical, physical address and i think the current value is correct because the meter responding and responsive. What could possibly go wrong? Is it regarding the title, block cipher, etc?

Hello Gurux Team,

We are currently facing an issue while reading meter data using Gurux DLMS libraries.

In the field, some meters are configured to return values with 6 digits (for example, energy or billing-related parameters). However, while reading these values through Gurux, we are consistently receiving only 5 digits, even though the meter display shows 6 digits.

Observations:

The meter display clearly shows a 6-digit value.

Gurux response contains only 5 digits for the same OBIS/field.
