Gurux DLMS for Java

Dear Sir,
This is parveen from panchkula. i have start a project in DLMS meter reading. My project architecture is following:-

1) DLMS Meters with RF Modules/GPRS connectivity
2) DCU connect with meters using RF modules and send data on server using GPRS mode on a specific TCP/IP port.
3) A Desktop application will run on server and Read data from TCP/IP port and store it into database.
4) A another application will get data from database and after decode it will store decoded data on another database.
5) On Server their will be a website for user . Web site will be use for create demands on DLMS meters and display data on website reports.

We are using ipv6 on DLMS meters and protocol is DLMS2 in energy meters.

I hope you understand the architecture of application.

Now my concern is i want to develop a desktop application which will run on server, Read raw data from database table , decode that data and store into in database. you just help me to provide DLMS Decode library build in java and tell me how i will use it. Raw data is in Encoded form please explain how i will decode it and store it into database.

Please help me out in this. I am using My Eclipse IDE 2019 4.0

Ok, Thanks for your revert sir,
I have already download but i don't know how i will execute it. I need a dll file which accept only security key , auth key, and encripted data and gives me the output. I also want to know how we can send and receive the command on DLMS meter. I am using my eclipse but i don't know how to run the project.

i have data plz check.

this frame is encrepted

auth key is TexasInstruments
and security key is TexasInstruments
please resolve and revert me.

Dear Sir,
you just convert data packet into xml. i want to know how i will decode it. Please decrypt it first after that decode. Please explain me how can i decode this data using your API. please explain sir.

Hi,
I have imported it as a maven project. Now please guide what is the next step for communication with meter. My meter is connecting using GXDLMSDirector using TCP/IP with IPV6. My meter is encryption enabled and working on wrapper. Please tell me the next step how i can download my Number Plate of my meter.

Kurumi

Hi,

There are several different parameters and if one of them is different from what the meter expects the connection fails.
Download GXDLMSDirector and try to connect with it. It will show the command line parameters so it's easier for you to connect.

Try to connect without an encrypted connection first. It's easier in that way. Change interface from HDLC to WRAPPER.

Its ok. But i want to know what is the starting step which i use to run the application in java.
I am easily connect with meter using GXDLMSDirector.
Which java file i run first for connect.
In which file i set parameter for connect with meter.

Hi Mikko,
Thanks for replying. I already downloaded this example. In gurux.dlms.client.example.java there are for java files like GXDLMSReader.java, GXDLMSSecureClient2.java ,sampleclient.java and Settings.java file. From these files sampleclient.java having main function. after running this file i got below output.

GuruxDlmsSample reads data from the DLMS/COSEM device.
GuruxDlmsSample -h [Meter IP Address] -p [Meter Port No] -c 16 -s 1 -r sn
-h host name or IP address.
-p port number or name (Example: 1000).
-S serial port.
-a Authentication (None, Low, High, HighMd5, HighSha1, HighGMac, HighSha256).
-P Password for authentication.
-c Client address. (Default: 16)
-s Server address. (Default: 1)
-n Server address as serial number.

Read LG device using TCP/IP connection.
GuruxDlmsSample -r sn -c 16 -s 1 -h [Meter IP Address] -p [Meter Port No]
Read LG device using serial port connection.
GuruxDlmsSample -r sn -c 16 -s 1 -S COM1 -i
Read Indian device using serial port connection.
GuruxDlmsSample -S COM1 -c 16 -s 1 -a Low -P [password]

Now please tell where i can put command line parameters. Please help me out.

Hi,

If you are running this from the eclipse, select "Debug as" and "Debug configuration...". Then add those parameters to the "Arguments" tab.

Got it. I have 2 meter. One is without Authentication and another is with Authentication. I am able to connect with without Authentication meter after passing the arguments. But i am unable to connect with Authentication meter after passing the arguments. I am getting the error
"Invalid parameter: India"
I am able to connect with GXDLMSDirector with Authentication. I just copy the command line parameters from GXDLMSDirector and past it in arguments tab.

Please guide me where i am doing wrong.

Hi,

I believe that you haven't add -d before India.

Thanks. Code is working fine. If i add some code from my side like decoded data insert in database then which file i use or i create my standalone java file.

Kurumi

Hi,

You need to use them all. It's easiest if you modify the example for your needs.

Is any normal and encrypted java decode packet file available. If yes then please let me know

kumarsoft.parveen

I need a packet decoder both normal or encrypted. Is there code available in java in which i insert received packet as it is and i received decoded or decrypted data.

Kurumi

Hi,

They are both in the same jar package. I need to warn you that DLMS is not an easy protocol. There is no simple frame (packet) that you send and get a reply. The PDU may come in multiple parts and each PDU might come in multiple frames (packets).

BR,
Mikko

Please give me a simple example to decode small packet

kumarsoft.parveen

Hi Mikko,
Downloading is working. Please tell me how i can decode normal DLMS packets or Encrypted packets Or provide me any reference from there i can learn and decode data packets. Or provide me any other solution.

I want when i receive packet i just decode it on same time and extract meaning full information.

Kurumi

3 years 9 months ago

Hi,

There is no simple answer to that. DLMS is a very complicated protocol. You need to read following standards:

IEC 62056-42 Physical Layer Services and Procedures for Connection-Oriented Asynchronous Data Exchange
IEC 62056-46 Data link layer using HDLC protocol
IEC 62056-47 COSEM transport layers for IPv4 networks
IEC 62056-53 COSEM application layer
IEC 62056-61 OBIS Object identification system
IEC 62056-62 Interface objects

I strongly prose that you use Gurux open-source libraries.

BR,
Mikko

kumarsoft.parveen

This is very time consuming. Is there any alternate or any service provide by you regarding decode received packet data. If any then please tell me.

Also tell me the which Gurux open-source libraries are present to decode the data.

Kurumi

3 years 9 months ago

Hi,

It's not just decoding the packet data. You must establish the connection for the meter and handle all cases. Reading DLMS meters is not an easy task.

You can use Java, C#, python, ANSI C or ANSI C++ programming languages.

BR,
Mikko

Is there any paid service which can help me to decode all received packet data or provide me java code in which i insert received packet and that code revert me decoded data.

Kurumi

Hi,

This is possible to do. Send an email to me so we can talk more about this option.

Hi,
Is there any code in java which can set the configurations in dlms meters. Also tell me where we use gurux.dlms.xmlClient,
gurux.dlms.simulator.java,
gurux.dlms.server.example.java

Provided by you.

Hi,

The client example is a good starting point. You can use it to do everything that you want to do.
You will use GXDLMSClient to communicate with the meter.

Hi,
Using Java client example i am able to downloads all from meters using command line argument but if i want to download only Inst data or billing data then what will be the command line string

Kurumi

3 years 9 months ago

Hi,

You can read single attributes with -g argument. I have to say that this is only an example and I believe that the best way is if you modify it for your needs. You need to give start and end time for read rows by range method and that is not in command line parameters. Check this out:

I have imported it in eclipse and code is working fine. I have create a connection using GXDLMSDirector , copy data from commend line and put it in Arguments in eclipse while running sipleclient.java. Smart Meter is communicating fine.

Now i want to know how can i download Complete Meter Inst data, Billing data, load profile data , event data, block load survey data in single single command and what parameters i will us in cmd line for doing this downloading task.
