Good day

I have command to read Load Profile, but don't know what the last byte should be.
This is for a Landis&Gyr meter. (E650)

Command:(IEC)
[Read Load Profile] 10 bytes [Date from] 6 bytes [Time from] 4 bytes [Separator] 2 bytes [Date to] 6 bytes [Time to] 4 bytes [command end] 3 bytes
[81 d2 35 82 50 2e 30 b1 28 30] [YY YY MM MM DD DD] [hh hh mm mm]
[bb 30] [YY YY MM MM DD DD] [hh hh mm mm] [a9 03 ??] <- this last byte is unknown.

Is there a formula for calculating this byte?
The value ranges between 20-29, a0-a9.

Hi

Its is first time setting up a EMI metering (LZQJ-XC).
Any tips on the way?

How to we select current transformer 5A/300A

We want to use RS485 DLMS and convert it to IEC61850 protocol. Using Kalkitech gatway, never used it before.

Thanks,

Hi,

we are trying to read Landis gyr ZCE Single phase meter through Gurux. Can we read this single phase meters through Gurux ? If yes then what parameters i have to set. Plz help

Hi,

How to know how many pulses/KWh a meter of type SL7000 761 will generate.
The CT ratio is 2500/1 A and VT ratio is 6.6KV/110V.
Using the software I read the configuration and settings of the meter but could't find the number of pulses per KWh.

Thanks,

Hi,

I am new for DLMS/COSEM. I want just try to make DLMS/COSEM Client. I want read a single register's data.
I have tried below mentioned code but it goes

"TRACE("Err! Failed to read register: Access Error : Device reports a undefined object" here.

Kindly suggest me.

Is it possible to implement End-to-End Encryption (E2E) within the meaning of "Greenbook 8.1 DLMS/COSEM Architecutre and Protocols" with gurux library?

We would need a possibility to have the following:
- API to seperately encrypt and decrypt COSEM objects as a seperate step before sending and after receiving data
- API to send and receive encrypted COSEM objects without decrypting them (broker functionality with only providing the connection handling and authentication)

Best regards
Christoph

Hi,

My question is about converting pulses that generated by energy meter to MWh or KWh.
The energy meter generates 5000 impulses/KWh. The CT ratio is 1200/5 Amps.
The VT ratio is 132kV/110 V.
On the HMI we need to display the energy value in MWh not pulses. So what formula should be used to convert the pulses to MWh. Does the VT and CT ratios should be take in account in calculation.

Thanks.

I am new to DLMS protocol.
I want to read Energy meter data using serial port
I use below setup
Ubuntu machine ----> RS232----> E250 meter

I didnt have any documentation to do that tast.

Please help me out

Hello. I am trying to use the relay outputs of the Iskra MT382 to control a relay. The COSEM object I am working with is 0.1.96.3.10.255 but I have no success so far in changing the relay status, which is constantly off.

Has anyone tried to control a relay with an energy meter with DLMS configuration?

Hi,

I have multiple dynamic IP meters of different manufacturer.

That are using different authentication key.

Issue is that which authentication key will use when a dynamic IP meter connect.

Query: Is there any option to get the meter serial number before authenticate the connection of dynamic IP meter.

Regards,
