Hi sir, for Manufacture = Indian Standard, HLS(2)=AES128
if client challenge = 1234567890ABCDEF, KEY = HHHHHHHHHHHHHHHH
1.which item we should input the KEY? Block Cipher Key or Authentication Key
2.which item we should input the service challenge?
3.the app should send packet for f(CtoS) as below
7E A0 2B 03 61 32 8D EB E6 E6 00 C3 01 C1 00 0F 00 00 28 00 00 FF 01 01 09 10 E9 15 92 8B E1

Hi,
I'm developing a smart meter, and referencing this open source code.
I've tested this code with parameters of 9.2.4.8.4 example in Green Book 7 as following:

System Title : 4D4D4D0000BC614E
Frame Counter : 01234567
Initialization Vector : 4D4D4D0000BC614E01234567
Block cipher key (global) : 000102030405060708090A0B0C0D0E0F
Authentication Key : D0D1D2D3D4D5D6D7D8D9DADBDCDDDEDF
Security control : 10
CtoS : 4B35366956616759 (“K56iVagY”)
StoC : 503677524A323146 (“P6wRJ21F”)

Hi,sir:
In HLS mode ,DLMSDirector could add a inputbox to write Client Chanllenge like 1234567890ABCDEF?
At present,the Chanllenge is a random number.
thank you!

Sir,
When i try to 'Read' objects in DLMSDirector , i got the following error - " System.Exception: GetObjects failed. Invalid Block number. It is 131074 and it should be 65538". please help me to solve this issue.

Hi

how can i , please, modify some service in conformance supported service, it seems that this can not be writable :

Hi Team Gurux,

First of all we would like to thank for your great effort to provide Gurux library.
We have successfully read Holley meter DTSD545 via serial port. Now we want to read same meter via tcp remotely, but little bit confused how we will identify the meter on the server i.e meter serial number.

Our meter is online and can provide server detail if you need.

Will appreciate your prompt response,

Regards,
Sohail

Hello everyone
I am a new member and i have some questions , these days i will download dlms director , i am interested to format the meter or calibrate it or write new records , can i do this with dlms director??
I bought used meters and i want install them on my customers pv field , but before the installation i want to check them if everything is ok

When a GXDLMSDirector device is set to GMAC authentication mode the password box is enabled, and connections won't work unless something is entered in that password box. It doesn't seem to matter what you put in the password box, as long as you don't leave it blank. Is this a bug, or is this password used for something I have missed?

Hi,

I need to read a HPL Single Phase meter using DLMSDirector. But this manufacturer is not listed. How can I configure the meter to read values?

Please help me.

Hi,

Tried to connect the Agnitio net meter via GuruXDirector (Low and High) password, got error message - Connection is permanently rejected, Authentication failure.

Tried with Kalkitech: able to communicate with meter successfully

Checked with meter vendor stating the issue got a reply as below,
IS 15959 (Part 2) - Advanced Security Profile is implemented in meter

GuruX supports this advanced security profile encryption?

Thanks
