Hey ! I would be grateful if anyone could help !

I’am working on a project, the main target is communicating with 5 energy meters alpha a1800. on ethernet TCP/IP using the serial ethernet converter ( EDW-100).
There are two scenarios for this :
*i can use the converter as a modbus gateway and read values via metercat (modbus tcp/ip).
*i can use GXDLMSDirector to read meters data via ethernet
i would like to contact someone who has worked on elster a1800 communication.

Greetings,

I am trying to communicate with a DLMS compatible meter that uses HLS-5 protection (equivalent in GuruX library to DLMS_AUTHENTICATION_HIGH_GMAC) over GPRS. I'm using the C++ version of the GuruX library. When calling the AARQRequest() function to generate an AARQ frame, the entire application crashes when calling the EncryptBlock function from the GXCipher class, specifically at line 562 for this piece of code "r0 ^= Shift(AES[block->c3 >> 24], 8);".

I tried to run in the guru dlmx solution "gurux.dlms.server.example.java" in eclipse but getting errors
Can any one suggest me.

Hello Gurux.
I need to connect to a SamGas GPRS meter, and i think i need some expert's help.

The meter is GPRS-type. When it establishes a TCP/IP connection, i accept it at my server, open another listening socket, and pipe them together, so that i can use DLMS Director for further communication.
(I tested this scheme on gurux server example and it works fine)

Meter's companion documentation declares that Public Client (0x10) is restricted to local optical port only. So i guess I have no ability to connect to it. (I will try though, with little hope)

I am newbie in this and would like to explore in this smart metering using Java version.

Given a raw data for Bill/Instant

How to decode and split the fields

I downloaded the code but do not have clue to the starting point. Could someone guide me

Thanks

Hi, I'm wondering if I can read this particular meter(Landys gyr e650) using only IEC62056-21 protocol mechanisms. I have my meter connected to the serial port via rs232 interface and what I'm trying to do is to get identification message after sending the standard IEC request, that is: "/?!\r\n" but I wasn't able to get any response whatsoever yet. I wanted to ask if anyone tried to do that and can tell me what port configuration should I use(baudrate, bits etc) or if this is even possible.

Thanks in advance

Hi,

I need to simulate a GXDLMSData array of BitString values.

GXDLMSData eventMask10 = new GXDLMSData("0.1.94.34.105.255");
eventMask10.SetDataType(2, DataType.Array);
eventMask10.SetUIDataType(2, DataType.Array);
eventMask10.SetAccess(2, AccessMode.ReadWrite);
eventMask10.Value = new object[2] { new byte[8] { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 },
new byte[8] { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 } };
currentServer.Items.Add(eventMask10);

Hi Sir,
I'm using HPL LT-CT Meter, TYPE: CT 05, -/5A and trying to connect the RS232 with the converter to read the values using GXDLMSDirector.

I've tried using Indian Standard, keeping all the settings as default, set serial with baud 9600 but couldn't make the meter connect to the software/

ERR: Failed to receive reply from the device in given time.

I've even changed the baud to 300,19200 etc but no response.

Could you help me with the communication of the meter with the software..
Thanks

Hi!

I am trying to connect to a meter (which is in server mode, as I understand it should be) using DMLS director. And whatever I try, I keep getting rejected.

Hi,

Has anyone got any general advice on how to talk to a CEWE Prometer using GXDLMSDirector?
It’s not listed as a meter in the dropdown menus.

Thanks in advance
