Product Description

While Siemens is a major player in industrial automation, the term “simulation output module” isn’t a standard, standalone hardware product in the same way as a digital or analog output module. Instead, this functionality is typically provided through software-based simulation platforms and specialized hardware designed for testing and virtual commissioning.

The core concept is to simulate the behavior of a real machine or process, generating “virtual” output signals that a PLC can react to. This is done to test and validate the PLC’s programming and the overall control system before connecting to real equipment.

Product Parameters

The primary Siemens product for this purpose is the SIMIT Simulation Platform. SIMIT isn’t a physical module, but a powerful software suite that simulates the behavior of plants, machines, and processes in real-time. It can be used for:

• Virtual Commissioning: Testing and optimizing the automation program on a digital twin of the plant.
• Operator Training: Providing a realistic, risk-free environment for operators to learn and practice.
• Factory Acceptance Testing (FAT): Performing comprehensive tests with the customer before the physical system is built.

Key “parameters” of the SIMIT platform and its related hardware include:

• Real-time Simulation: SIMIT simulates the process in real time, allowing for a dynamic and accurate test of the control logic.
• Connectivity: SIMIT can connect directly to a SIMATIC PLC (or even a virtual PLC like S7-PLCSIM Advanced) via protocols like PROFINET or PROFIBUS. It can also connect to third-party PLCs.
• Libraries: SIMIT includes extensive libraries of pre-built simulation models for a variety of components, such as valves, motors, sensors, and even entire process units, which speeds up the creation of the digital twin.
• Scalability: The platform can handle simulations of varying complexity, from a single machine to a complete, large-scale plant.
• Hardware-in-the-Loop (HIL): For advanced testing, dedicated hardware modules can be used. For example, specific PROFINET I/O modules can be used to connect the SIMIT software to a physical PLC. The SIMIT software sends the simulated I/O signals through this hardware to the PLC, providing a more realistic test environment.

Product Advantages

Using a simulation platform like SIMIT offers significant benefits in the automation lifecycle:

• Reduced Commissioning Time: You can start testing and debugging your PLC program long before the physical hardware is installed, which drastically reduces the time needed for on-site commissioning.
• Lower Costs: Virtual commissioning reduces travel expenses, minimizes the need for expensive hardware changes, and prevents costly mistakes on the factory floor.
• Increased Safety: You can test dangerous or complex scenarios in a risk-free, virtual environment, ensuring the safety of personnel and equipment.
• Improved Quality: A thorough simulation helps you find and fix bugs and optimize the control logic, leading to a more robust and reliable final system.
• Effective Training: Operators can be trained on a realistic digital twin of the plant, improving their skills and confidence without risking damage to production equipment.

Important Considerations

While powerful, simulation requires careful planning:

• Accuracy of the Model: The quality of the simulation is directly dependent on the accuracy of the digital twin. If the virtual model doesn’t accurately represent the real-world process, the test results may be misleading.
• Cost and Complexity: For very simple applications, the cost of the simulation software may outweigh the benefits. SIMIT is most valuable for complex, large-scale projects.
• Integration: Ensure that the simulation software is fully compatible with your specific PLC hardware and engineering software (e.g., TIA Portal).

Product Applications

Simulation modules and platforms are used extensively in industries where testing is critical:

• Process Industries: Simulating a chemical plant or a water treatment facility to test complex control loops and safety interlocks.
• Automotive: Validating robotic assembly lines and paint shops before they are physically built.
• Machine Building: Testing the entire control sequence of a new machine design and optimizing its performance.
• Energy Sector: Simulating the behavior of power plants or grid systems to test control strategies and operator response to emergencies.
• Logistics and Material Handling: Validating the control logic for complex conveyor systems and automated warehouses.
