Automated PLC Testing with Python & asyncua: Continuous Integration for Industrial OT

Bring modern software CI/CD practices to industrial controls: writing automated test scripts with Python asyncua, asserting PLC state transitions, and load testing OPC UA servers.

  • Python asyncua provides full asynchronous asyncio support for connecting to OPC UA servers and subscribing to tags.
  • Automated integration tests can verify 500 emergency interlocking permutations in 60 seconds without risking machinery.
  • Integrating tests into automated pipelines catches regression bugs before code is loaded into production PLCs.
