Hi,

Check GetReadOut method. It reads all objects and attributes of each object.

Hi Mikko,

we are getting this error If we run with single Obis code without attribute, but we want to get all values related to that OBIS code.
Thanks

Hi Mikko,

Hi Mikko,
We are getting OBIS codes from meter right.Is that OBIS codes are saved anywhere.For that we have any code?
Thanks

Hi,

You need to add attribute index after the OBIS code. Like this:
0.0.40.0.2.255:2

You can save OBSIS codes to the file and read them when needed.

BR,
Mikko

Hi Mikko,

We tried that also still we are getting the error. Like this:

Hi,

There is no object "0.0.40.0.2.255: in the association view. You need to change the authentication level.

BR,

Mikko

Hi Mikko,

where we need to change the authentication level? Directly while running we have to give otherwise we need to make changes in code. We gave like this:
C:\Users\test.EMMYS1546\Desktop\Gurux.DLMS.Python-master_old version\Gurux.DLMS.Client.Example.python>main.py -S COM3-a low -P lnt1

Thanks.

HI,

You must Give authentication level as "Low". You also need to change client address.
Something like:

main.py -S COM3-a Low -P lnt1 -c = 1

Mikko

Hi Mikko,

We tried like u said but it's disconnecting, we are getting like:

once look into it.

Hi Mikko,

Hi Mikko,
Is it necessary to give Attribute index along with OBIS code in command prompt to get all attribute values of that OBIS code or else Is it sufficient to give only OBIS code.

Thanks
waiting for your fast rply

Hi Ram,

Hi Ram,
ExtendedRegister issue is fixed. Get the latest version (1.0.27).

Attribute index is mandatory. You can modify the example for your needs if you don't want to give attribute index.

BR,
Mikko

Hi Mikko,

For every OBIS code of 2nd attribute index we are getting error instead of values
something like:

Hi,

GXDLMSCaptureObject contains a reference to an object. You can get OBSIS code from there.

Version 1.0.27 is interesting. I can see the version here:
https://pypi.org/project/gurux-dlms/

But when I run pip install --upgrade it updates to version 1.0.26.

Maybe they are making some improvements to pypi.org and we need to wait for a while.

BR,

Mikko

Hi Mikko,

Is it possible to retrieve OBSIS code from GXDLMSCaptureObject? If possible how?

Thanks

Hi,

It's something like this:

I'll create profile generic object here:
pg = GXDLMSProfileGeneric()

for k, v in pg.captureObjects:
print(k.logicalName)

BR,
Mikko

Hi Mikko,

For every OBIS code of 2nd attribute index we are getting error instead of values
something like:

Thanks

Hi,

Hi,
You need to read capture objects first before you read profile generic buffer.

1. Read attribute 3. (capture objects)
2. Read attribute 2. (buffer)

BR,

Mikko

Hi Mikko,

In get parameters function we added the code like below to get all attributes of OBSIS code, here we have fixed the attributes using range function but when we try with getattributeIndex function we are getting error. how to solve this issue.
elif it.tag == 'g':
# Get (read) selected objects.
for o in it.value.split(";,"):
tmp = o.split(":")
if len(tmp) != 2:
if len(tmp) == 1:
for i in range(1,8):
tmp.insert(1,i)
self.readObjects.append((tmp[0].strip(), int(tmp[1])))
else:
raise ValueError("Invalid Logical name or attribute index.")

Thanks

we are getting date.time object we are not getting values there, how and where to modify it.
Thanks

for some values we are

for some values we are getting bytearray why is it like that?

Hi,

For GXDateTime use str() method to transform it into the string. You are receiving byte arrays because the meter is sending a value as byte array.

BR,

Mikko

what about reply 72

Hi Mikko,

Thanks
waiting for reply

Hi,

I prose that you add a list of attributes what you want to read. Like this:
-g "0.0.1.0.0.255:1;0.0.1.0.0.255:2"

BR
Mikko

Hi Mikko,

Hi Mikko,
That is okay we are able to get values using attribute index.but we want to get all values directly using obis code.that is also we are able to do it.
But if we want to getattributeindextoread() function in gxdlmsSettings.py which package/library i need to import.
Thanks

Hi,

Amount of attributes depends on the object you want to read.
You need to create that object what you want to read first and then ask how many attributes there are.

Mikko
