Getting started with Echo

[jorge-sepulveda]

Hello!

I came across this library and wanted to see if I can talk to Echo PLC's. This is what I currently have in place. Running studio 5000 version 37 and trying to talk to an Emulate 5580 that is running in echo.

from pycomm3 import LogixDriver
import logging
logging.basicConfig(level=logging.DEBUG)
# Connect to the PLC
with LogixDriver("10.0.0.10",slot=1) as plc:

    value = plc.read("LI_210006")  # Replace with your tag name
    if value is not None:
        print(f"Tag Value: {value.value}")
    else:
        print("Failed to read tag.")

This is what I'm getting for the output. It seems pycomm can identify what it's trying to connect to but fails to connect.

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

Any suggestions would be greatly appreciated!
