Hi.
This log files GX and Monitor COM port.
No work two bytes server address.
The reason for the method "client.GetData(rd, reply, notify)", line 327 GXDLMSCommunicator.cs
Reply frame rd[]={7E A0 21 21 02 19 73 F9 65 81 80 14 05 02 00 80 06 02 00 80 07 04 00 00 00 01 08 04 00 00 00 01 80 8A 7E }
You can correct this error?
Thanks.

Hi,

I can't read pic that you have posted. Please, send data as plain text in the future.

The actual reason why reply fails is that header CRC is wrong in the reply packet.

Ask your meter manufacturer to fix it.

Indeed, you are right.

I’m a soft&hard developer of measuring devices, I write and test myself using your application "GXDLMSDirector".
Here is the error line of my program:
crc = CalcFcs(buff,8);
The number of bytes in header should be variable, not fixed.
Thanks again. Next I will be attentive.
Regards, Albert.
