A training digital twin should connect control logic to observable behavior and testable acceptance criteria. Start with the engineering question, then add only the fidelity needed to answer it.
Follow the workflow
Choose whether the model must train operators, test PLC sequences, validate throughput, inspect collisions or demonstrate a concept. One model rarely needs maximum fidelity in every dimension.
Do this in the product
Open the component library and choose the minimum sensors, actuators and material flow for the objective.
Open the exerciseMap commands, feedback and fault states explicitly. A motor command should not imply proven motion; model contactor, drive or sensor feedback separately when the acceptance test needs it.
Do this in the product
Run a 3D scenario and inspect the same inputs and outputs that drive the ladder program.
Open the exerciseDefine initial state, stimulus, expected sequence, time limits and safe final state. Test interlocks and recovery as well as the happy path.
Do this in the product
Use the existing scenario test harness and commissioning paths to create repeatable evidence.
Open the exercisePackage normal operation, induced faults, solution replay and a limitation statement. Record which plant behaviors are represented and which remain outside the model.
Do this in the product
Pro 3D sandbox, advanced faults and team reports turn the public demonstration into a reusable training workspace.
Open the exerciseCore concepts
The simulator creates a repeatable result; these concepts make that result transferable to real vendor software and supervised practical work.
The degree to which relevant geometry, timing, physics, logic and data match the target system.
Testing automation logic against a model before or alongside physical commissioning to find sequence and interface defects earlier.
Linking each requirement to a test, result and model version so handover evidence remains understandable.
Continue in the workspace
Run the foundation exercise publicly, then use a subscription for advanced challenges, saved configurations, full attempt history, sharing, assigned paths and team reporting.

Competency and practice field guide
Direct answer
The learner can define the decision a twin supports, state model and data boundaries, test synchronization and explain where simulated evidence ends.
Written for controls engineers, instructors and operations learners comparing simulated assets, virtual commissioning models, synchronized operational twins and training scenarios.
Decision purpose, physical asset, model variables, fidelity, time scale, data sources, identity, synchronization, uncertainty, validation, lifecycle ownership and access control.
Physical or simulated asset state through acquisition, mapping, model update, prediction or scenario, comparison, decision, action and retained outcome evidence.
One bounded operating case stays synchronized within declared tolerances and produces a result checked against independent evidence.
Missing data, clock drift, model bias, changed equipment, sensor fault, stale configuration, network loss, version mismatch and restart.
An asset-identity, sensor, time, mapping, model, parameter, synchronization, prediction, decision or governance mismatch.
The model validated for its intended use with current asset evidence, target interfaces, uncertainty limits and accountable lifecycle ownership.
It teaches how a purpose-bounded model relates to an identifiable asset, current data, synchronization, validation and decisions rather than treating any animation as a twin.
It may be one component of a twin or virtual commissioning model, but the label requires explicit asset, data, synchronization, fidelity and lifecycle claims.
