Query about RLRQ

Forums
General discussion

Hi, I'm trying to read EDMI meter via serial port and everything working good except the RLRQ.. When I send RLRQ the meter has sent back the following packet 7E A0 07 21 03 31 17 21 7E.. Since Gxdlms director doesn't have Release option so I'm sending the RLRQ manually via docklight application after the SNRM and AARQ packets. The blue book denotes that the RLRE also will contain the user information but I'm not getting like that.
My SNRM frame 7E A0 07 03 21 93 0F 01 7E

Profile generic - Python

Forums
General discussion

Hello, first of all I want to thank you for your work is really amazing.

I have managed to read the records of an actaris meter. But what interests me most is to read a record of the 'Profile Generic' 0.1.98.1.0.255.

I am using Python 3.7.

If you could tell me how reading these records would be, I would appreciate it.

I tried with
GXDLMSProfileGeneric ()
and with readRowsByEntry ()
but I haven't got much

To read this record in 'GXDLMSDirector' I achieve it with read 1 count: 1
Getting the data I need

Server ID clarification

Forums
General discussion

Hi peoples in forum,
I'm confused about server ID and authentication.
I'm clear about server ID length identification from gurux article. my doubt is, is it any standard is there like if Authentication is none then the server ID should be in this many bytes?
My understanding is, from mechanism name only we can identify the Authentication level. Kindly revert me about the reason behind the byte size of the server ID.

Thanks & Regards,
Sha M.
