Option A – 3D model (STEP, JT, FBX)
Is used when kinematics or mechanical movement are to be simulated.
→ Goal: visual, physical representation of the machine in space.
Option B – P&ID (Piping and Instrumentation Diagram)
Is used when flow, pressure, valves, actuators, signals are important.
→ Goal: functional simulation of the plant logic.
Option C – Selmo structural model (Plant, HWZ, SEQ, Zone)
Is used to emulate the logical sequence deterministically.
→ Goal: complete hardware and process emulation.
4.2 Hardware emulation
Every signal (from PTF-IO) is reproduced in the simulation as a logical bit or analog value.
CMZ, MXIC, interlocks and sequences are adopted 1:1 from the bit control logic.
This creates a digitally deterministic mapping of the real control layer.
