Dear sir,
We are making the the meter reading software but facing issue in LN with ciphering
As per green book and your comment about one post that
AES-128-GCM require
1. System title 2. Block Cipher key 3. Authentication key 4. Dedicated key 5. Frame counter

Hi ,

Hope You feel great , there is a difference between IEC 62056-21 and DLMS ?

Hello Mikko,

I tried reading clock from the meter using DLMS client example in C. everything is fine except the year value. It reads as 120 instead of 2020 or 20. Can you please tell me how can i fix this?
Clock structure screenshot is attached here.

Here is the trace:

Hello Mikko,

If i ignored Dynamic memory allocation by enabling the macro
DLMS_IGNORE_MALLOC, The software will work without any modifications or else
should i create statically allocated variables for buffers. Please clarify.

Hi,

We are interested to implement a communication profile based on the protocol Prime through PLC (check the scheme in the picture attached).

Like we know when using the serial communication or TCP-UDP we are choosing the interface HDLC in the gurux client as protocol of communication. The connection starts always by an SNRM request from the client followed by an UA frame from the server then the AARQ and AARE (application layer).

Hi Mikko,

We read this information from your site "https://www.gurux.fi/Gurux.DLMS.Iec#ModeECPlusPlus" to support what we are writing below.

We know that if we are using IEC handshake with serial port we must first send identify command and move to mode E.

We will enumerate the steps below (correct me if we are wrong):

1- The client sends to the server "/?!\r\n" without the quotations. This requests the identity information from the device.

Hey ,

In OBIS code : A.B.C.D.E.F , the number B of communication channel refers to what ?

Thank You ,

Hello,
I am trying to read data (and "clone") from Sanxing device ( https://www.dlms.com/product/SX5A2-SELS-04_140 ) using network (also I have tried serial line) with no success.

I have executed (using java build of simulator):

java -jar simulatorBuild.jar -h 192.168.133.12 -p 8088 -o sanxing_template.xml -t Verbose -w

Hi,

I just compiled gurux.dlms.c client demo and got 2 warnings that migth cause some problem:

src/gxset.c: In function ‘cosem_setSwitchTable’:
src/gxset.c:7811:44: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]

Is there any policy regarding warnings?
