Learn SIMIT-SCRIPTING with Real Code Examples

SIMIT scripts allow engineers to define dynamic simulation behaviors beyond graphical components.

Scripts simulate sensors, actuators, process physics, fault conditions, and operator scenarios.

Provide logical flow using event-based or cyclic execution models.

SIMIT scripting integrates seamlessly with TIA Portal, PCS 7, and SIMATIC PLC emulation.

Used for virtual commissioning, FAT/SAT reduction, and operator training systems.
