Hello.
I need to do a GET reading on a meter.
I have the obis, it claims class 7, and I need to read attribute 2:
I am reading attribute 3 first and then I read attribute 2 using class GXDLMSProfileGeneric
To make the reading I need to send in the GET command one of the parameters below, to select what I want to read:
- 02 02 04 06 00 00 01 53 06 00 00 02 2d 12 00 00 12 00 00
- 02 02 04 06 00 00 01 52 06 00 00 02 2d 12 00 00 12 00 00
How would I add these parameters to the command, using gurux?
I’m using Java Link in the implementation.
Thanks!
Hi,
Hi,
You can read only one value at a time with correct implementation using -g parameter. You can add a new object and read it like this:
GXProfileGeneric pg = new GXProfileGeneric("Logical Name");
//Read columns,
read(pg, 2);
//Read data by start and end time.
readRowsByRange(pg, start_tiem, end_time);

I need to do a reading by
I need to do a reading by sending a command type GET I know the obis, class 7.
I’m reading attribute 3 first
However, to read the attribute 2 of this command I need to send an Accessselection. However, I don’t know how to add this to the get command.
Below how the manufacturer is sending the command:
7E A0 2C 03 03 32 49 EA E6 E6 00 C0 01 C1 00 07
00 00 63 63 00 FF 02 01 02 02 04 06 00 00 01 52
06 00 00 02 2D 12 00 00 12 00 00 F6 67 7E

<UInt16 Value="0" />
</Structure>
</AccessParameters>
</AccessSelection>
</GetRequestNormal>
</GetRequest>
</PDU>

I would like to know how can I add this:
<AccessSelection>
<AccessSelector Value="2" />
<AccessParameters>
<Structure Qty="4" >
<UInt32 Value="338" />
<UInt32 Value="557" />
<UInt16 Value="0" />

</Structure>
</AccessParameters>
</AccessSelection>
Thanks.
Hi,
Hi,
You can use ReadByRange or ReadByEntry methods of the GXDLMSClient for reading only part of profile generic data.

Could you, please, give an
Could you, please, give an example of I can submit this struct: <AccessParameters>
How can I send that
Thanks.
Hi,
Hi,
You will use readRowsByEntry method to generate this method. Like this:
pg = GXDLMSProfileGeneric("0.0.99.99.0.255")
client.readRowsByEntry(pg, start_index, end_index)
Check the client example. It will do everything that you want to do.

Hello.
Hello.
Actually, I would like to know how to send the struct along with the get command, because I already know how to send the desired date limits.
Follows below the Structure I need to add:
<Structure Qty="4" >
<UInt32 Value="338" />
<UInt32 Value="557" />
<UInt16 Value="0" />
<UInt16 Value="0" />
</Structure>
Thanks!
Hi,
Hi,
readRowsByEntry will send get command where is structure as you describe.
client.readRowsByEntry(pg, 338, 557)
