Addressing

Hello ,

I have a problem regarding server(meter) addressing

in the raw HDLC frame
the destination address should be 0x00 0x02 0x00 0x03 &
the source address should be 0x03

in order to do the the above what should be the ServerAddress in the Gurux.DLMS.METER.Listener.Net example code ? here is the code snippet

GXDLMSClient client = new GXDLMSClient();

client.UseLogicalNameReferencing = true;
client.Authentication = Enums.Authentication.None;
client.Password = null;
client.InterfaceType = Enums.InterfaceType.HDLC;

client.ClientAddress = 0x01; //this is okay
client.ServerAddress = 0x0001; //I am stuck here

Thank you

Hi,

client.ServerAddress = 0x4001;

Dear Mr Kurumi

I want to understand how gurux calculates logical address of the server address
For example if i put the following values at GXDLMSDirector Software

client address = 1= 0x01
logical server = 1= 0x01
physical server = 10 = 0x10

Then According to DLMS address theory , for 2 byte address size
in the HDLC frame

client address should be 0x03
locical address should be 0x02
physical address should be 0x21

the generated hdlc snrm frame by GXDLMSDirector software is
0x7E 0xA0 0x08 0x02 0x21 0x03 0x93 0x86 0xC1 0x7E

this is okay ,it matches with the theory
but in the C# client code the output frame does not match

here is my code snippet
------------------------------------------------
client.ServerAddressSize = 2;
client.ClientAddress = 0x01;
client.ServerAddress = 0x0110;
-----------------------------------------------
and here is the output hdlc snrm frame
----------------------------------------------
Send SNRM request.0x7E 0xA0 0x08 0x04 0x21 0x03 0x93 0x1C 0x8A 0x7E
----------------------------------------------

So does the client code calculated address differenlty than the GX software ?

It would be great if you reply
Thanks A Lot & Best regards
