Thanks, Chris. Here is a bit of code that produces the error: ``` import pyads conn = pyads.Connection(ams_net_port=10000, ip_address="10.10.10.10") with conn: state = conn.read_state() print(state) ```

@kryskool, port 10000 is for the system service. My TwinCAT 3 C++ task defaults to port 350, but the issue exists on both ports.
