Master read classes output to json?

[Saleem344]

Hi I'm new to dnp3 protocol I'm reading an outstation using pydnp3 I want to take the required classes output in the program so that I can make the required output format can anyone help me??

my Code :

`
from pydnp3 import asiodnp3, asiopal, opendnp3, openpal
import time

    FILTERS = opendnp3.levels.NORMAL | opendnp3.levels.ALL_COMMS
    HOST = "192.168.0.69"
    LOCAL = "0.0.0.0"
    PORT = 20000


    class TestMaster:

        def config_master(self):
            # Callback interface for log messages
            self.handler = asiodnp3.ConsoleLogger().Create()

            # Root DNP3 object used to create channels and sessions
            self.manager = asiodnp3.DNP3Manager(1, self.handler)

            # Connect via a TCPClient socket to an outstation
            self.channel_listener = asiodnp3.PrintingChannelListener().Create()
            self.channel = self.manager.AddTCPClient("tcpclient",
                                                    FILTERS,

can anyone help me with how can I take the classes output in my program so that I can make the output in my required structure like a dictionary or list?

Thank you for your help.

Hi @Saleem344!
Did you manage to solve this?
I am also in need of this information to register in a DB.
