Python Package for communication with Siemens Tecnomatix Plant Simulation

This package enables the communication with the simulation software product "Tecnomatix Plant Simulation" by Siemens. It speaks to PlantSim via the COM interface from within Python and includes useful mappings for some more complex PlantSim data types like tables.

Example

import os
import sys
import time

import plantsim.plantsim as ps
from plantsim.simulation_data import SimulationData

if __name__ == "__main__":
    # Create a new plant simulation
    sim = ps.PlantSim(version="23.2", license_type="Student")

    # Load a model
    script_dir = os.path.dirname(os.path.abspath(__file__))
    models_path = os.path.join(script_dir, "..", "models")
    if not os.path.exists(models_path):
        print("Error: models folder not found")
        sys.exit(1)

    sim.model = os.path.join(models_path, "Prueba_conexion 2.spp")
    sim.path_context = ".Models.Model"
    sim.event_controller = "EventController"

    sim.initialize()

    experiments = [
        SimulationData(
            input_variables=["inspeccion", "inspeccion"],
            values=[False, True],
            output_variables=["simulacion", "simulacion"],
        ),
        SimulationData(
            input_variables=["inspeccion", "inspeccion"],
            values=[True, False],
            output_variables=["simulacion", "simulacion"],
        ),
    ]

    # Measure time for parallel execution
    start_time = time.time()
    parallel_results = sim.run_simulations_in_parallel(experiments)
    parallel_time = time.time() - start_time
    print(f"Parallel execution time: {parallel_time:.2f} seconds")

    # Measure time for sequential execution
    start_time = time.time()
    sequential_results = [sim.run_simulation(exp) for exp in experiments]
    sequential_time = time.time() - start_time
    print(f"Sequential execution time: {sequential_time:.2f} seconds")

    # Compare results
    print("Parallel results:")
    for result in parallel_results:
        print(result)

    print("Sequential results:")
    for result in sequential_results:
        print(result)
