Why Co-Simulation Matters
PLC co-simulation links your control program with a dynamic plant model so logic can be tested against realistic process behavior.
It catches signal timing and sequence issues early, reducing late commissioning work in the factory.
Minimum Setup
Define I/O mapping, time synchronization, and scenario scripts before test execution.
Keep the first suite focused on core machine states, fault handling, and restart sequences.
- Explicit signal dictionary and ownership
- Deterministic replay for failure scenarios
- Pass and fail criteria tied to process KPIs
Scale to Regression
Once baseline tests are stable, automate nightly runs and compare behavior across software changes.
Treat virtual commissioning as a continuous engineering asset, not a one-time project artifact.
