Hi Mikko,

I am working on a Python application using the Gurux GXDLMS library and need assistance with managing the invocation counter dynamically. Specifically, the counter value should be retrieved from the 16 association (logical name: 0.0.43.1.3.255) and then updated dynamically in the 48 association. The update can either use the exact value retrieved from the 16 association or apply an increment (e.g., adding +1 or +10 to the retrieved value). I would appreciate guidance or examples on how to implement this functionality effectively to ensure accurate and dynamic updates.

GXDLMSScriptTable obj = new GXDLMSScriptTable("0.0.10.0.1.255");
obj.Description = "MD Reset Action";
GXButton btn = new GXButton();
btn.Text = "Execute";
btn.Target = obj;
IGXDLMSView obj1 = new Gurux.DLMS.UI.GXDLMSScriptTableView();
btn.View = obj1;
GXActionArgs ve = new GXActionArgs(obj, 1);
GXDlmsUi.UpdateAccessRights(btn.View, client, btn.Target, false);
ve.Client = client;

HI Mikko,

I am attempting to access 16 associations in my meter using the GXDLMS library. During the setup process, I encountered an error when trying to set the ciphering security to Security.NONE. The error message states:

AttributeError: 'GXDLMSClient' object has no attribute 'ciphering'.

Setup Details:

Serial Port: COM3, configured with 9600 baud rate, 8 data bits, no parity, and 1 stop bit.
Client Address: 16
Server Address: 1
Authentication: NONE
Interface Type: HDLC

and I code I wrote is:

I have been trying to connect to Hexing HXF300 electricity meter using serial number because I want to read data from multiple meters, but it seems doesnt work. I dont know if it is because Hexing does not use standard formula or what else. Does anybody know the formula for Hexing HXF300 meter?

Thanks in Advance

Hi Mikko,

"I am working on a Python application using the Gurux GXDLMS library and need help modifying my code to read Profile Generic parameters. I understand that I first need to establish the association by reading the PC (Public Client) association. The invocation counter retrieved from the PC association needs to be updated in the US (User Side) properties before proceeding.

Dear Sir,

We have to write Metering Mode in 0 to 1 0r 1 to 0 .

We require simple Python code to read from check meters using DLMS and an optical probe USB cable.

This seemed the best place for my topic but pls let me know if it belongs elsewhere.
I have a Kaifa MB310H4BNL digital (electricity) meter (in Netherlands). Please note I don't have prior experience reading meter(s), I am learning as I go and objective is to read my meter.

Hi,
i am trying to read clock of dlms meter over serial port in c#. but i am pretty new to this, and don't find any proper way to work. please share me sample code to read clock (refered Gurux.dlms library and developed basic code but it is not working- code given below). serial port setting(baud rate, comport) done. thanks

GXDLMSClient dlmsClient = new GXDLMSClient(true,30,1, Authentication.None, "RMI_SECRET_ASSC2", InterfaceType.HDLC);

Hello Sir,

Recently we got our Smart Gas Meter tested in CTT 4.3 release 103 for certification. In the test "Read logical_name' of an instance Id 0.0.42.0.0.255 returns "Exception Response" in PC mode.
Here is the Request-Response Hex values.
