DLMS Client installed in RUT 906, connected DLMS Meter via serial RS485 2 wire all setting done signal ok no error. But Actual Data Not received in Test Result.

Hello,

Just to confirm, could you tell us if the following topic is the same exact issue as yours?

DLMS client integration with Landis & Gyr E650

Good Day, I’m having trouble retrieving valid data from the meter via DLMS. I have successfully been able to communicate and extract DLMS data via MAP 110 on TCP/IP. But when I try to retrieve it via the Teltonika Router DLMS Client, it gives me empty values and incorrect Date and time. { “error”: 0, “result”: { “Clock”: { “LGZ58652375”: { “2”: “01/00/1900 00:00:00 UTC+00:00” } }, “Identification number 1.1”: { “LGZ58652375”: { “2”: “” } } } } Any advice on what the problem mig…

Are you also receiving data, but it’s empty?

Regards,
M.

Could you kindly provide an image of the wiring, please?

Thank you,

This is the same issue I’m experiencing via TCP communication to a meter with the DLMS Client.

Do you have a solution for getting data?

[prabhu5992]

@VictordeBeer ..Do you have a solution for this problems? How to resolve.

[MatasR]

Hello,

@prabhu5992 , we’re still waiting on Victorde’s feedback to a solution that we’ve proposed to them so we can’t say for certain that the resolution is 100% a fix here.

Here’s what the R&D had to say when they were analyzing Victorde’s setup:

Client has a meter that uses short name referencing instead of logical name referencing , because option use_ln_ref is 0 . However, for the cosem, he uses OBIS code 0.0.42.0.0.255 which should only be used for logical name referencing. He should be using short name reference (something like 1234 )

M.

[VictordeBeer]

Hi @MatasR , I did not receive this feedback. I will have a look and post any findings.

[VictordeBeer]

Good Day, I get the same result:

Meter:

Clock readout setting on router:

Incorrect date and time:

[VictordeBeer]

@MatasR - any feedback on this?

[MatasR]

Hi there,

Will pass this information to the R&D if you do any further tests, kindly email me.

Regards,
M.

[prabhu5992]

Hi all @MatasR @VictordeBeer

Good day

I tested further Short name instead of OBIS code (6 digi)…now reading Clock value is correct , Energy Value need to convert the actual value and still we observing

[MatasR]

@VictordeBeer could you double check your settings and see if they’re any similar to prabhu5992’s? Especially the OBIS code & short name, since you didn’t post your Device parameters.

You can use the “Scan” functionality in our device to get all available objects and check if the short names are correct.

[VictordeBeer]

Using the short name as per the Scan on the Teltonika Router provides me with the correct time:

[MatasR]

Could you confirm that this is the solution to the issue and that it works as expected now?
