I'm testing an embedded LN-only DLMS/COSEM server with the GXDLMSDirector Application Conformance Test. 13 of 14 tests pass; the only failing one is T_APPL_DATA_LN_N1, and it always fails on subtest 3 ("Read non-existing object").
The tool sends a GET for a non-existing object (class 15 / Association LN,
OBIS FF FF FF FF FF FF, attribute 1):
C0 01 C1 00 0F FF FF FF FF FF FF 01 00
The overall result is always:
T_APPL_DATA_LN_N1 subtest 3 succeeded when Short Name referencing is used.
T_APPL_DATA_LN_N1 failed.
Hi,
I am trying to communicate with a smart meter over GPRS communication. I am using Gurux.DLMS.Push.Listener.Example.python to read the data from the meter. But I am getting below errors:
I am new to the DLMS and energy meter domain. I am working on interfacing a Saral 100 energy meter (Secure Meters) with my microcontroller over the RS232 protocol. I’ve received some initial details from the vendor, but I want to confirm what exact parameters and values are required from the manufacturer to ensure proper communication and data reading.
Here’s what I have so far:
Voltage Levels – RS232 standard voltage levels (3–5 V depending on signal type).
Serial Communication Settings – Baud rate: 9600 bps, Parity: None, Stop bits: 1.
