kandi X-RAY | python-opcua Summary

python-opcua is a Python library typically used in Networking applications. python-opcua has no bugs, it has no vulnerabilities, it has build file available, it has a Weak Copyleft License and it has medium support. You can download it from GitHub.

Pure Python OPC UA / IEC 62541 Client and Server Python 2, 3 and pypy. OPC UA binary protocol implementation is quasi complete and has been tested against many different OPC UA stacks. API offers both a low level interface to send and receive all UA defined structures and high level classes allowing to write a server or a client in a few lines. It is easy to mix high level objects and low level UA calls in one application. Most low level code is autogenerated from xml specification, thus adding missing functionality to client or server is often trivial. coverage.py reports a test coverage of over 95 % of code, most of non-tested code is autogenerated code that is not used yet.

QUESTION

Python opcua module CancelledError

Asked 2021-Mar-15 at 12:11

I am currently trying to connect to an OPC UA server, which was set up on my local device as a test environment. The server was not set up by me, it is not implemented in python (think it might be json). I wanted to connect to it using the following code:

...

From the error it seems the Python client is trying to connect using the UA Binary TCP transport but you have been given an HTTPS endpoint URL.

Perhaps you need to use a different endpoint URL to connect to this server? Maybe it’s opc.tcp://{PCName}:4840/opcua if it’s using the default port.
