Hello. i am trying to write a code to connect and read data from a meter using tcp/ip in C#(VS2017).

I get the sample codes from official site. I downloaded the nugets.
However there are undefined variables, some terms unkown by .dll's. I could not clean the errors

Is there any simplest, shortest sample codes for doing basic job, please?

Hi,

I have a modem that needs to be start with transparent mode to connect by sending a special command then continue Dlms reading.

Is there an option in Gurux to set a command after settings.Media.Open(); before reader.InitializeConnection(); ?

Should below code do the job? And what is "receiver" in this case?

settings.Media.Open();
settings.media.Send("command-to-switch", receiver);
reader.InitializeConnection();

Hello Mikko,

We are using Gurux DLMS C library with IGNORE_MALLOC in our Three phase meter. Currently we trying to do Image Transfer using Gurux Director. But meter replied with error ( Device reports read / write failed).

Issue area:

in invoke_ImageTransfer function, imageActivateInfo.size value is 0.
if ((ret = arr_getByIndex(&target->imageActivateInfo, target->imageActivateInfo.size, (void**)&item, sizeof(gxImageActivateInfo))) != 0)
{
return ret;
}

Trace Details:

Hi, Mikko!
How can I set TimeZone and Status into attribute 'time' of Clock (class_id: 8), not in separated attributes it?
For filling last 3 bytes of datetime struct, ex.: 07 E4 09 09 FF 16 0F 00 FF <80 00 00>.
And what better use Clock_obj.time.value.datetime.tzinfo or Clock_obj.time.timezone?

Hi,

I have managed to set listener on my machine and arrange push list on the meter. When I trigger pushing from GXDLMSDirector by pressing the push button, meter connects and sends the push list.

However, it doesn't send anything when I set the date time via Communication Window panel. It's written on the meter, but meter doesn't send push by itself.

Hi Mikko,

I'm trying to read Profile Generic parameters by range, but it's not working. I'm able to read by entry without problem (using latest python lib version).

Hi Mikko,

Can you please provide details on Prepayment metering for Indian Standard?

Thanks & Regards,

Hi

When I use Director I can read from and write to clock.
However, using Gurux.DLMS.c, I can only read the clock, the write operation does not return any data and does not update the clock.
I am using HLS, and I have filled the object struct like this:

data = {0x07, 0xE4, 0x09, 0x08, 0x02, 0x11, 0x00, 0x00, 0xFF, 0x80, 0x00, 0x00};
LN = {0, 0, 1, 0, 0, 255};
memcpy(object.logicalName, LN, 6);
object.objectType = dlms_Object_Type_Clock;
bb_set(&object.access->attributeAccessModes, data, sizeof(data));

hi gurux,

I am a newbie to dlms and I want to build a custom dlms test tool using gurux nuget pkgs in c#. my quick questions on this are

a. Can i do it? use gurux nuget pkg to build my custom app,
b. I could not find any help on nuget pkg/ APIs / call sequence, it would be great if you could help me with.

thanks,
Jayaraj

Hi Mikko,

After doing the connect/disconnect load and getting push event from meter.

I have configured the following properties of the Client to decode and parse push events.

Client.Ciphering.SystemTitle
Client.Ciphering.AuthenticationKey
Client.Ciphering.BlockCipherKey

But, From Client.GetData(eventsData, replyData, notify) got following error:

"Data is ciphered using different security level. Actual: 48. Expected: 0"

Can you please provide an update on this ?
