Hi there,
We are trying to test the DLMS Object Library supplied by Texas Instruments. http://www.ti.com/tool/DLMSOBJ-EVAL
So I downloaded the library programmed an MSP430 board and connected it through a serial port to my PC. Downloaded the Gurux DLMSDirector and downloaded the manufacturer list. I connected using the following settings
Manufacturer: Gurux
Start Protocol: DLMS
Media: Serial
Authentication: None
Logical Name Referencing (checked)
Client Address : 10
Address Type: Default
Physical Address: 1
Logical Server: 0
Serial Port : COM2
The meter connects and then when I hit the read button I get the following object list.
0.0.1.0.0.255
0.0.40.0.0.255
0.0.40.0.1.255
0.0.41.0.0.255
0.0.42.0.0.255
Why don't I get the other object codes back from the meter (like Active Energy or reactive energy etc.)? I think only these 5 are available to the Public client? Am I right? How can I connect to the meter with some other association? When I try to set the Authentication to High or low I am unable to connect. I have seen on the port sniffer that there is no reply from the meter whenever the client address is other than 10. When the authentication is Low the client Address is 11 and when it is high it is 12. But the meter doesn't reply...
The library states that it supports three associations: No Security (NS), Low Security (LS) and High Security (HS).
Can you tell me what should I do next? I am stuck at this point...
Meters do not reply anything if Server ID or Client ID is wrong. I check from that link you added that you should use client ID 0x20 (32) to read your meter.
Thanks for the reply... Yes I should have read the document more carefully. It was clearly stated that for no authentication I needed to connect using client address as 16 and for low authentication I need to connect using Client Address 32 and for High Authentication I need to connect using Address 48. But somehow I missed it I think because of Hex and Decimal numbers.... I am able to connect using Low Authentication but I am unable to connect using high authentication. I have the same problem as what baycan has and he has posted a log in the other thread. So I will follow your advice there to get connected using High Authentication....
Hi,
I am doing my final year project on smart energy meters. I have trouble downloading the library for MSP-430. Please share the DLMS OBJ library to the e-mail ID mentioned below. Thank you.
