Simple Python code example needed
Hello all

I am interested in experimenting with DLMS/COSEM component but I am having a little trouble using the sample code as I am not so experienced in Python

The idea is simply to readout a given data from a DLMS based meter using the optical comm. (e.g. "voltage on L1 ..")

I m interested to know how to use available class and modules of GXDLMS + GXserial for reading and writing

I would very much appreciate if someone could post a simple and specific code example written in Python 3.x using the component just for this purpouse.

Thanks in advance

Hi,

You can't just get a readout in DLMS. Download GXDLMSDirector and use it to get familiar with DLMS.
You need to know OBIS code and interface type to read value from the meter.

This client example does exactly what you want to do. It reads all the data from the meter.
You can modify it so it reads only values that you want to.

Hi kurumi,
Thank you very much for your quick response and input for my query, I m using similar tool to read energy meter and familiar with DLMS OBIS codes and various associations used in it, Now I am trying to explore meter reading and testing via python scripting and need your valuable inputs to use gurux_dlms package and it's various module; for that I need your support in creating scripts.

Please Help Thanks
regards

can anybody share a simple

can anybody share a simple code (python)
for ex. Reading clock without any security using command from gurux_dlms package.
1. port setting
2. association
3. then readout

Thanks in advance
regards

Hi,

All settings depend from the manufacturer. Try to run Gurux.DLMS.Client.Example.python with parameter:

python main.py -S COM_PORT.

Update COM_PORT to serial port what you are using.

Hi,

Can you run this with -t Verbose parameter and post trace here?
Can you connect to this meter with GXDLMSDirector?

Hello, Mikko and Riyaz, I am

Hello, Mikko and Riyaz, I am also getting a similar error. My problem is that I am having trouble getting even the settings from my manufacturer (EDMI). Please do you have such settings for low or No authentication access for EDMI MK6E meters!

Hi,

Install GXDLMSDirector and try to read your meter with that. If you can't read it verify from meter vendor that your meter is supporting DLMS. There are versions from EDMI MK6E that don't support DLMS.

Hello Mikko,

I have installed GXDLMSDirector and I am still unable to connect to both EDMI MK6E and Actaris SL7000 and even ACE6000 from Itron. All the meters are DLMS complaint. it says so on the front panel of the meters. I figure I must be doing something wrong. I am trying to connect using an optical probe on COM10. I can read the meters through the manufacturers software (EDMI & Ace Pilot)

Hello Jaafar,

Try to change the start protocol from IEC to DLMS. Can you see what baud-rate you are using in Ace Pilot or EDMI?

Hello everyone,

Does someone help me to find server SM DLMS/COSEM simulator example in Python? I want to start to develop my own DLMS/COSEM client using Python, but still I don't have my own Smart Meter device.

Thanks in advance.

Good afternoon!!! You

Good afternoon!!! You provided a good link for reading parameters. And it is possible with the help of this example to calculate PROFILE_GENERIC with the time interval I need. I make a request (python main.py -S com1 -r sn -g 1.0.99.1.0:2) I get
raise Exception("Unknown logical name:" + k)
Exception: Unknown logical name:1.0.99.1.0
Looking forward to your help!! Thank you!
