Socket Timeout #27

Open gucluceyhan opened 2 years ago

gucluceyhan commented 2 years ago

Hello,

I am trying to implement this code but every time I try I am having 'Socket Timeout' warning.

The meter is Kohler AEL.TF.19 which is using IEC62056-21 protocol to communicate. I am sure that the both the meter and the modem are running perfectly since when I tried it with HW-Group's Hercules Software it connects and gets the data.

If you can help me about the process I'll be glad.

from iec62056_21.client import Iec6205621Client client = Iec6205621Client.with_tcp_transport(address=('5.26.220.136', 502), dev$ password_challange = client.access_programming_mode() client.send_password('00000000') # Common standard password data_answer = client.read_value('1.8.0')

OK. What happens when you just try to do a standard readout:

from iec62056_21.client import Iec6205621Client

client = Iec6205621Client.with_tcp_transport(address=('192.168.0.1', 8000), device_address='12345678', password='00000000')
client.connect()
print(client.standard_readout())

Also if you have some debug output that would be good.

The above exception was the direct cause of the following exception:

OK. So the device wont even reply.

First thing is to omitt the address. Just set it to "". This usually works for point-to-point interfaces.

It could also be that the modem does not do a conversion to 7E1 and you need to so that client side. See my answer here for more info: https://github.com/pwitab/iec62056-21/issues/16#issuecomment-754783281

If your Hercules program have a communication log it would be good if you could add it to the issue to see if they are doing stuff in a weird way.
