Dear Sir,

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

byte[] systemTitle = Encoding.Default.GetBytes(textBox_Ser_sys.Text);
byte[] BlockCipherKey = Encoding.Default.GetBytes(textBox3_encription.Text);
byte[] AuthenticationKey = Encoding.Default.GetBytes(textBox2_authentication.Text);
byte[] lls = Encoding.Default.GetBytes(textBox4_lls.Text);
Client = new GXDLMSSecureClient(true, 20, 1, Authentication.Low, textBox4_lls.Text, InterfaceType.HDLC);
Client.Ciphering.Security = Security.AuthenticationEncryption;

Client.Ciphering.SystemTitle = systemTitle;//HexStringToByteArray("71 77 65 72 74 79 75 69");
Client.Ciphering.BlockCipherKey = BlockCipherKey;
Client.Ciphering.AuthenticationKey = AuthenticationKey;
Client.Password = lls;
Client.ChallengeSize = 0x16;
// Client.Standard = Standard.India;
Client.ServiceClass = ServiceClass.Confirmed;
Client.MaxReceivePDUSize = 65535;
Client.UtcTimeZone = true;
//Client.W
Client.ClientAddress = 0x20;
Media = new GXSerial();
GXSerial serial = Media as GXSerial;
serial.PortName = cmbPortName.Text;
serial.BaudRate = 9600;
serial.DataBits = 8;
serial.Parity = System.IO.Ports.Parity.None;
serial.StopBits = System.IO.Ports.StopBits.One;
pack_num = "Port Connecting";
Thread.Sleep(100);
Application.DoEvents();
InitializeConnection();
GXDLMSData data = new GXDLMSData("0.0.94.96.19.255");
object obj2 = Read(data, 2);
GXDeltaUInt8 d1 = new GXDeltaUInt8(1);
data.Value =d1;
byte[][] ddd= Client.Write(data, 2);

Meter not updated with new value

Hi,

Your data type must be the same as the meter uses.
Read the value and check what data type your meter uses and change GXDeltaUInt8 to the correct data type.

Dear Sir,

After reading data type is Uint8.
we are using same.
when we are using GXDLMSDirector mater has updated .
Unable to understand where are we missing .
Please help us.
Thanks

Hi,

You are not using the same data type.
In your code you are using GXDeltaUInt8, not GXUInt8.
You need to change it.

Dear Sir,

We are unable to find GXUInt8 only available GXDeltaUInt8.
may i know in version this available ?.
So we just changed by this way but till not updated in meter.

GXByteBuffer buffer = new GXByteBuffer();
buffer.SetUInt8(1);
data.Value = buffer.GetUInt8();
byte[][] ddd= Client.Write(data, 2);
Thank You.

Hi,

You have selected the serial port group and I don't know what programming language you are using. If you are using C# you can do it like this:

data.Value = (byte) 1;
byte[][] ddd= Client.Write(data, 2);

Dear Sir,

I am using c#.

When we are using GXDLMSDirector .exe meter value updated in meter, log are given below-

Both Authentication are same only deferent between LLS(C#) and HLS ( GXDLMSDirector) .

We have not getting any type of error but value not updated in meter but when i used GXDLMSDirector value updated .

Please help us how can we resolved this?.

Hi,

I need your block cipher key to decrypt the data.
Use the example that I shared with you.

Dear Sir,

Our block cipher key=bbbbbbbbbbbbbbbb

LLS key- AAAA1234
HLS key- BBBB1234BBBB1234
HLS FU key- CCCC1234CCCC1234
system title- qwertyui
Authentication & Encryption key- bbbbbbbbbbbbbbbb

We have checked with as per your guideline but meter value not updated
GXDLMSData data = new GXDLMSData("0.0.94.96.19.255");
object obj2 = Read(data, 2);
data.Value =(byte)1;
byte[][] ddd= Client.Write(data, 2);

Thanks Advanced .

Hi,

I can see from your trace that the meter is returning Success.
Everything is working as expected.

Dear Sir,

We have 2 manufacture make meter and both are similar behavior meter updated data by GXDLMSDirector with HLS but meter data not updated by C# .

I think meter support only with HLS , any idea to use HLS instead of LLS in c# code.

Hi,

GXDLMSDirector is made with C#.

You can see the command line arguments for the client example when you select the meter. You need to use those arguments to establish the connection to the meter.

Dear Sir,

May i know any refences code for arguments to establish the connection with GXDLMSDirector.

We unable to find example in client example.

Thanks Advanced

Hi,

The connection parameters depend on the used meter model.

If you can connect with GXDLMSDirector you can see the correct command line arguments to the client example when you select the meter in GXDLMSDirector.
