Good afternoon,
I'm having trouble importing the project https://github.com/gurux/gurux.dlms.java in Eclipse. I tried to import straight from Github for my machine and then
I tried to run the main (GuruxSerialExampleJava.java) and appeared several errors:
Exception in thread "main" java.lang.NoClassDefFoundError: MediaStateEventArgs

So I tried to create a new main class with the steps in the example (http://www.gurux.fi//Gurux.DLMS) and in the first step I checked the
client.setClientID methods ((byte) 0x21); client.setServerID ((byte) 0x3); do not exist in GXDLMSClient.java class. What am I doing wrong? How should I care
the library?
Grateful!

Hi,
Hi,
Read scaler first.
it = GXDLMSRegister("1.0.12.7.0.255")
#Read scaler
client.read(it, 3)
#Read value.
client.read(it, 2)

How to read profile generic
How to read profile generic data for load profile...?
help me read those data
Hi,
Hi,
Something like this:
GXDLMSProfileGeneric pg = new GXDLMSProfileGeneric("OBIS Code");
//Read capture objects
Read(pg, 3);
//Read buffer.
Read(pg, 2);
You can also use readByEntry or ReadByRange to read buffer. All meter's don't support them for all the profile generics.

The output came like this...i added -t Verbose to the parameters.
code :
load_prof = GXDLMSProfileGeneric("1.0.99.1.0.255")
read(load_prof, 3)
print(read(load_prof, 2))
I ran the code again and i got like this:

Hi,
Hi,
I have check this and meter reply is invalid.
Meter returns this:
C4 01 C1 00 FF 0F 02 12 00 00 02 04 12 00 04 09 06 00 01 60 0C 05 FF 0F 02 12 00 00
It should be this:
C4 01 C1 00 01 0F 02 12 00 00 02 04 12 00 04 09 06 00 01 60 0C 05 FF 0F 02 12 00 00
Can you ask the meter manufacturer to fix it?

yeah i will ask them ... and
yeah i will ask them ... and how to read data using Push setup

Hi,
Hi,
You can use GXDLMSClient.GetData method to parse push messages. Just set correct parameters for the GXDLMSClient.
Note! you must use this method and give notify parameter.
GXDLMSClient.GetData(reply, GXReplyData data, GXReplyData notify)
BR,
Mikko
could u pls explain through
could u pls explain through sample code in python how to set parameters and to parse push messages with an example
Hi,
Hi,
Is your meter sending push messages to the same client that has connected to the meter or is meter sending push messages to the specified IP address?
You can check this reading Push Setup Interface.
If the meter is sending push messages to a connected client, check readDLMSPacket2.
It prints received push messages to the console.
BR,
Mikko
Yeah i want the meter to push
Yeah i want the meter to push the message to connected client ...
We just have to set the parameters like this ?
pushlistener = GXDLMSPushSetup("0.0.25.9.0.255")
pushlistener.numberOfRetries = self.read(pushlistener,6)
pushlistener.repetitionDelay = self.read(pushlistener,7)
pushlistener.randomisationStartInterval = self.read(pushlistener,5)
pushlistener.communicationWindow = self.read(pushlistener,4)
pushlistener.pushObjectList = self.read(pushlistener,2)
Hi,
Hi,
You can config meter like this. Check readDLMSPacket2 to see how you can get received push messages.
BR,
Mikko
pushlistener =
pushlistener = GXDLMSPushSetup("0.0.25.9.0.255")
pushlistener.numberOfRetries = self.read(pushlistener,6)
print(pushlistener.numberOfRetries)
pushlistener.repetitionDelay = self.read(pushlistener,7)
print(pushlistener.repetitionDelay)
pushlistener.randomisationStartInterval = self.read(pushlistener,5)
print(pushlistener.randomisationStartInterval)
pushlistener.communicationWindow = self.read(pushlistener,4)

pushlistener.sendDestinationAndMethod = self.read(pushlistener,3)

255 is not a valid DataType
Ended. Press any key to continue.
Process finished with exit code 0
So i think i need to send the push data to different IP address which i read from attribute 3 ...
if i try to print that it's printing something different...and if i try to read push objects list it's displaying error that 255 is not a valid type ...
so could u please check the trace whether it's normal ?
i guess it's meter's fault ....i got the same (255 is not a valid type) when i try to read objects for profile generic data
Hi,
Hi,
You need to define IP address and then you can start gurux.dlms.push.listener.example. It'll listen incoming messages and shows them.
Invalid type is coming because the meter is sending the wrong data type. You can invoke push message calling activate.
Something like this:
GXDLMSPushSetup push = new GXDLMSPushSetup();
byte[][] data = push.activate(client);
Then send data to the meter to activate the communication process.

There is no push listener
There is no push listener example in python ...(first lemme try with connected client)
So after setting parameters to push setup object ...how to receive push messages( for connected client) using readDLMSPacket2 function.As i am new to DLMS can u explain in detail please
Hi,
Hi,
You don't need to set parameters for push setup object. Just start to listen TCP/IP port and when the new connection is established parse data using GXDLMSClient.GetData method.
You can get idea from java example.

Mikko

Hi Prashanth,
Hi Prashanth,
Please, if you have a new question create a new topic. I believe your path is causing the problems. Use an easier path. This error message is coming from java.
