This virtual environment allows a manufacturing automation controls engineer to validate programmable logic controller (PLC) and human- machine interface (HMI) code before they are downloaded to real equipment; therefore, testing the tooling, robots, transfer lines and other equipment that comprise highly automated manufacturing systems.

 By simulating and validating the automation equipment virtually, it can be confirmed that the equipment will work as expected--significantly reducing system installation cost and startup time. This approach can also lead to better software quality and increased safety

•By means of virtual commissioning, manufacturing systems, real plants as well as their related control programs can be tested before being constructed

•Debugging and correction efforts will be significantly reduced during implementing and running the real industrial applications

By means of digital models, computer-aided planning and design, computer-aided engineering, associated software tools and with the aid of integrated data management, the “Digital Factory” would permit integrated planning, simulation and validation of manufacturing processes and systems
