DLMS shut down electric source

Dear all,
We are working on communicating a EMH meter in Java with DLMS. For now, we have tried to make the connection and AARQ Request. Actually, we have 3 phases connected to the device, and we want to control each phase to provide or not electric current and therefore, control their comsumptions. We are beginners in DLMS Protocol, so we dont know how to implement this feature following the protocol. Could anyone kindly provide us some hints or some good tutorial to start with?
Thanks in advance and regards

Hi,

You should first install GXDLMSDIrector. You can read your EMH meters with it.
When you press Refresh it will read all registers what meter can offer.
Then you can select what registers you want to read and implement application for your needs.
You can get source code from github. www.github.com/gurux

Thanks a lot for your answer.

Thanks a lot for your answer. However, when we try to connect via GXDLMSDirector, we obtain the following error: "Failed to connect in given time". Here i attach the log and two pictures with the concrete device and the configuration of the manufacturer.

Dear all,

Dear all,
Does anyone know anything else about this configuration?
Thanks in advance

EMH meter

Hi,

Get latest version from GXDLMSDirector. Let me know if that don't help.

Thanks for your response. In

Thanks for your response. In fact, we just tried with the newest version, but we obtain the same error. We think it is because of the configuration, but we dont find any document with a proper description of such parameters.

EMH meter

Hi,

Each meter manufacturer is using different parameters. If one of manufacturer settings is wrong, meter is not reply anything. We'll try to read our EMH meter and I'll let you know if we found anything.

EMH

The same issue here!!!
With the lastest version of GXDLMSDirector we can not connect to the EMH meter.

EMH

Hi,

I updated new EMH settings file. Please, let me know if you still have problems.

Still with errors

Dear Mikko,
We tried to connect again using the same configuration that you proposes in your last version of the software. We had to change the port 4059 to 8000, because we only have this port open. The error is the same ""Failed to connect in given time". Our model is emh lzqj-xc, just in case it would be helpful.
Thanks a lot for your help

EMH

Hi,

Our client is using port 1000. Make sure that port is correct. Check that your values are same what are here:
http://www.gurux.fi/GXDLMSDirectorExample

If it still fails, send trace from first sent packet (SNRM request).

BR,

Mikko

EMH

I checked what you suggest, and it is correct. Please, find attach the trace of the SNRM packet.

Hi,

I just realized that you are using Moxa or other serial port converter. Is that so?
Make sure that serial port settings are baudrate 9600 8N1.
You must also check that DLMS is starting protocol from the meter.
