Inputs for the Digital Twin from the PTF

The digital twin can only function reliably if all information from the PTF complete, consistent and structured are present.

PTF area	Relevant data for the DT	Usage
Process (P)	Process description, states, parameters	Definition of the logical state machine
Technology (T)	Sensors, actuators, interfaces, buses	Hardware emulation, signal behavior
Function (F)	Function definition, monitors, triggers	Function logic, simulation of action sequences
PTF-IO	Signal addresses, CMZ level	Connection between control and simulation
PTF-PARAM	Process parameters, limits	Adjustment of simulation models
PTF-FUNC	Mathematical formulas / logical linkages	Physical or algorithmic behavior
PTF-RISK	known risks / non-conformities	Prioritization of scenarios to be simulated
