Feature
Operate running twin instances with live state, runtime actions, and controllable behavior before hardware is available.
Runtime Control & Live State is the SPX capability for operating a digital twin after it has been generated or selected from a model library. Teams can start an instance, inspect live values, trigger actions, and watch behavior change while the runtime is active.
