Digital Factory: Virtual Commissioning - Revolutionizing Manufacturing

The manufacturing landscape is undergoing a significant transformation, driven by advancements in technology and the increasing demand for efficiency, flexibility, and speed. Central to this evolution is the concept of the Digital Factory, a virtual representation of a real-world manufacturing environment. Within this digital realm, Virtual Commissioning (VC) plays a critical role, offering a powerful suite of tools and techniques to optimize processes, reduce costs, and accelerate time-to-market. This comprehensive guide explores the intricacies of Virtual Commissioning, its benefits, challenges, and its impact on global manufacturing.

What is Virtual Commissioning?

Virtual Commissioning is the process of testing and validating automation software, including PLC programs, robot programs, and HMI interfaces, in a virtual environment before deploying it to the physical production system. It involves creating a digital twin, a highly accurate simulation of the real-world production system, including mechanical components, electrical systems, and control logic.

Instead of testing directly on physical hardware, which can be time-consuming, costly, and potentially dangerous, Virtual Commissioning allows engineers to simulate the entire production process in a virtual environment. This enables them to identify and resolve potential issues early in the development cycle, minimizing risks and improving overall system performance.

Key Components of Virtual Commissioning:

• Digital Twin: A faithful digital representation of the physical production system, including mechanical components, sensors, actuators, and control systems.
• Simulation Software: Software tools that simulate the behavior of the physical system, allowing engineers to test and validate control logic in a realistic environment. Examples include Siemens PLCSIM Advanced, Emulate3D, Process Simulate, and ISG-virtuos.
• PLC/Robot Controllers: Virtual representations of the programmable logic controllers (PLCs) and robot controllers that control the physical system.
• Communication Interfaces: Virtual interfaces that enable communication between the simulation software and the virtual controllers, mimicking the communication protocols used in the real-world system (e.g., OPC UA, Profinet).

Benefits of Virtual Commissioning

Virtual Commissioning offers a wide range of benefits for manufacturers across various industries. These benefits can be categorized into cost savings, time reduction, improved quality, and enhanced safety.

Cost Savings:

• Reduced Downtime: By identifying and resolving potential issues early in the development cycle, Virtual Commissioning minimizes downtime during the actual commissioning phase. This can translate to significant cost savings, especially in industries where downtime is extremely expensive.
• Lower Travel Costs: VC facilitates remote collaboration and testing. Experts across different geographies can collaborate on the project eliminating or reducing the need for international travel which can be costly.
• Reduced Material Waste: VC allows engineers to optimize processes and identify potential problems that could lead to material waste during the actual production phase.
• Reduced Damage Risk: Testing changes in a virtual environment eliminates the risk of damaging expensive machinery during commissioning.

Time Reduction:

• Faster Commissioning: Virtual Commissioning significantly reduces the time required for physical commissioning by identifying and resolving issues in advance.
• Shorter Development Cycles: By enabling parallel development of hardware and software, Virtual Commissioning shortens overall development cycles.
• Faster Time-to-Market: The combined effect of faster commissioning and shorter development cycles results in faster time-to-market for new products.

Improved Quality:

• Optimized Performance: Virtual Commissioning allows engineers to optimize the performance of the production system before it is even built, resulting in higher throughput and improved quality.
• Error Reduction: By thoroughly testing and validating control logic in a virtual environment, Virtual Commissioning reduces the risk of errors and malfunctions during the actual production phase.
• Early Issue Detection: Virtual Commissioning allows for the early detection of design flaws or control logic errors. This early detection reduces the cost of rework and prevents costly delays during implementation.

Enhanced Safety:

• Safe Testing Environment: Virtual Commissioning provides a safe environment for testing potentially hazardous scenarios, such as emergency stops or robot collisions.
• Risk Mitigation: By identifying and resolving potential safety hazards in a virtual environment, Virtual Commissioning helps to mitigate risks in the real-world production system.
• Improved Operator Training: Operators can be trained on the virtual system before the physical system is even built, improving their skills and reducing the risk of accidents.
