Hello,
I am using the DLMS/COSEM python library to read data from an Actaris meter (SL761B070). However, I have not been able to establish communication with it.
When trying to communicate, I get the following errors:
Data send a file try to resent 1/3
Data send a file try to resent 2/3
RX 14:5317 DisconnectRequest TimeoutException ('Failed to receive a reply from the device in the given time')
I tried the GXDLMSDirector (user interface GUI), and it works fine. I do not understand why the GXDLMSDirector is working, and the library doesn't if the base code is the same. I am using TCP communication for both (GXDLMSDirector and DLMS/COSEM python library). These are the CmdParameter that I am using "-h IP -p PORT -s 17 -c 1 -r sn -a Low -P ABCDEFGH "
please someone I can help me

Hi,
Hi,
Actaris is using Logical Name referencing, so remove -r sn.
I believe that the reason why the meter doesn't reply is that it's using 4 bytes addressing.
That is usually needed and it's not implemented to command line client.
You need to manually add this after you have created the client.
cl = GXDLMSClient()
cl.serverAddressSize = 4

Hi, Thanks for your response,
Hi, Thanks for your response, I try the suggestions you mentioned, but I haven't been able to communicate with the meter.
Maybe I am doing it wrong, could you tell me where to place the commands you mention?
The user interface works great, is there a way to send data to the meter, from the libarary, the same way the interface does?
Hi,
Hi,
Can you run your python app with -t Verbose parameter and post the first trace line here. I'll check your settings. I believe that one of the settings is wrong and the meter doesn't reply. Are you using the same baud-rates?

Mikko
Thank you very much for your
Thank you very much for your reponse,
After running the python app with -t Verbose parameter I get the following results:
>python main.py -h 166.210.134.4 -p 5000 -s 17 -c 1 -a Low -P ABCDEFGH -t Verbose
Authentication: Authentication.LOW
ClientAddress: 0x1
ServerAddress: 0x11
TX: 10:36:52 7E A0 07 23 03 93 B7 12 7E
Data send failed. Try to resend 1/3
Data send failed. Try to resend 2/3
RX: 10:37:22
DisconnectRequest
The communication we are using for the library and the GUI is TCP/IP. The information is sent via TCP/IP to a second device which function is to retransmit the TCP/IP information to the serial port of the ACTARIS configured at 9600 bauds.
Everything works fine for the GUI (TX: 7E A0 08 02 23 03 93 3E 74 7E) but not for the library.
Hi,
Hi,
Change server address from 1 to 145.
python main.py -h 166.210.134.4 -p 5000 -s 145 -c 1 -a Low -P ABCDEFGH -t Verbose
