I am working in a project where need to communicate with NON DLMS meters that use the IEC 62056-21

Is it possible if Gurux serial can be used to handle the communication

Hi,

I’ve been working with the GURUX library for ANSI C and ran into an issue.

When I try to set the value of an object class_id = 1 and an attribute of type OCTET_STRING, I’ve noticed the following:

If I read the object first and then set it, inside svr_postWrite(dlmsSettings* settings, gxValueEventCollection* args) I get args->size == 1.

If I don’t read first and I write directly, then in the same function args->size == 0, which means no post-processing happens after the write.

Hi,
How can I set counter number with number only like GuruxDLMSDirector without obis code. I'm using gurux DLMS.Python.client

Good day all. I want to take readings from a DLMS meter to an ESP32 and send tokens from ESP32 to the meter.

1. I need a mentor. I am willing to pay for your time
2. I need a meter manufacturer suggestion that can give me this functionality. I will order a test sample

Thank you.

Hi,

I'm having problems connecting my meter to the XmlClient main.py file

I'm using this command:
python ./main.py -S COM6 -t Verbose -i HdlcWithModeE -c 16 -w 1 -f 256 -x "./Messages/LN/GetAssociationView.xml"

And receiving:

Hi.
I have a device with a physical address of 6538. I'm setting this address in GURUXDirector. But in the command line parameters, this address looks like "-s 22922" What's the formula for converting 6538 to 22922?

I am trying to make a new installation of the python DLSM/COSEM application. Testing the standard listener application gives the following feed back. What is the reason?

Hi Mikko, good day.

I have with me an Itron SL7000 meter. Using correct parameters I can connect to it and read some data using Gurux DLMS Director. I managed to read the daily load profile by range. Then i try to read using ESP32. I can connect to it using ESP32, but when i try to read load profile by range, the code throws some errors. Here's the code that i use:

Hello,

I have two variants of energy meters. I have taken the GuruxDLMSDataCollector example for dlms client integration in my MCU. One of the meter is working fine reading obis profiles without "update Invocation counter". But another meter needs Invocation counter this i verified with Gurux director so it needs "Invocation counter". So can you provide a piece of code for my micro controller for to read "Update Invocation counter".
It's urgent if possible can you provide me ASAP.

Hello.

Im triying to create a COSEM object class_id = 1 (DLMS_OBJECT_TYPE_DATA) of type structure. This structure will contain 4 different values. First 2 of them will be uint32 and last 2 will be int32.

The way i'm creating this object is the following:

gxData myMEASURES;
static dlmsVARIANT vUA, vIA, vPA, vQA;
uint32_t g_rmsUA, g_rmsIA;
int32_t g_rmsPA, g_rmsQA;
#define MAX_MEASURES 4
static dlmsVARIANT arrElements[MAX_MEASURES];
static variantArray arrBuf;
