Gurux DLMS for ANSI C

Hello!

I have implemented a DLMS server on a Texas Instruments C2000 microcontroller, based on the ANSI C server examples. Communication is established over PLC, and I have already implemented serialization of the PRIME API on the C2000. The DLMS server interface I am using is TYPE_PDU.

Producing large size response packet on US Association

Forums
Gurux DLMS for ANSI C

Hi,

We are developing indian standard meter . In wrapper communication interface of US Association, existing gurux library is producing large size of response buffer when reading objects. Can you please suggest a suitable encoding mechanism to reduce the response buffer size when reading objects for less memory consumption.

Here is the below request-response .

High Authentication Problem

Forums
Gurux DLMS for ANSI C

Hello, I downloaded the project in the path "https://github.com/Gurux/GuruxDLMS.c/blob/master/Keil/NUCLEO-L433xx/Gur…; to my computer. I uploaded it to my own meter. I managed to connect to the meter and communicate with it using Gurux GXDLMSDirector. However, when I set the Authentication level to High and enter the password as "Gurux" as you indicated, I get the error "Access Error : Device reports Read-Write denied".

Gurux DLMS for ANSI C

Hello!

I’m implementing a DLMS server on a c2000 Texas Instruments microcontroller based on the ANSI C server examples. Communication is established via PLC, and i have alredy implemented a serialization of the PRIME API on the c2000. The interface I'm using for the DLMS server is "TYPE_PDU".

After making some small modifications, I’m attempting to connect to the server from GXDLMS Director running on a PC, with Microchip’s Prime Manager software handling DLMS over TCP (Prime manager also has a serialization of PRIME API).
