The architecture of V5.4 SP8 was designed to be lightweight yet robust. Unlike modern high-fidelity physics simulations, PLCSIM focuses on logic verification. It does not simulate the electrical physics of a motor burning out or the fluid dynamics of a valve; rather, it ensures that the Boolean logic and mathematical algorithms governing those devices are correct. This distinction is crucial: PLCSIM is a logic validator, not a process simulator.
