[Web address removed.]

i can read most of meter via it with iec62056 protocol mode C and E.
now i want to add dlms its. i use mode E and send command and get respond from meter ACK 2 Z 2 CR LF
but i dont know how i can continue ??

Hi,

I propose that you use Gurux open source libraries to read your meter. DLMS is not a very easy protocol. You need to start with baud rate 300 7E1 and change it after you have established the connection with IEC. The meter returns the baud rate that it wants to use.

i know i know
but i dont know how i can use dlms library in mode E.
Iv sent command /?! then meter respond xxxz\2 so W is 2
next i send ack for meter and meter respond ack and now it is ready for dlms
i dont know what request send for it to read dlms protocol

Hi,

Your meter is not in Mode E and you can start to use DLMS. DLMS is a binary protocol where IEC 62056-21 is ASCII.

Hi,

First, check that your meter is supporting DLMS. If it is, then you can use for example GXDLMSDirector to read your meter. It might be that your meter is supporting only IEC 62056-21 and then you can't read the meter with DLMS.

Hello
I uploaded the sample Arduino code for dlms to the ARDUINO MEGA2560 hardware tracking and connected the optical probe to the Arduino board via serial connection according to the instructions.
I ran it on the ACE5000 meter, but no response was received in the monitor series, and only the submitted codes are displayed.
Please advise.
Thank you

Hi,

Try to read your meter with GXDLMSDirector first. It will save a lot of time.
Select "Itron" as a manufacturer and try to connect. I don't know what baud rate you should use so you must try to find the correct baud rate.
