Key Advantages

Close to native speed

open62541 performance core leads to magnitudes of speed-up over a pure Python implementation.

Certification Ready

The open62541 example server is certified for the OPC UA Standard Server profile. This shows the standard-compliance, feature-completeness and robustness.

Simple Python API

Deep Python integration leads to a simple API that is still feature-complete.

Full Type Hints Coverage

Type hints reduce the number of programming errors and allow large-scale refactoring with confidence.

Stability and Error Recovery

Long-term testing and advanced error recovery ensure a maximum uptime of OPC UA and your industrial application.

Seamless AI and Computer Vision Integration

Integrated support for numpy-arrays, the big-data standard for AI and Computer Vision.
