SIMATIC/SIMOTION Virtual Commissioning with Hardware in the Loop

  • Entry
  • Associated product(s)
To lower risks and effort of the real commissioning of a machine, virtual commissioning is an efficient alternative. This application example describes how to build up a hardware in the loop scenario with a SIMOTION or SIMATIC controller. Using NX MCD, SIMIT and SIMIT Unit you can virtually commission your machine.

Using STEP 7 and the TIA Portal you can create a hardware in the loop (HIL) scenario to simulate and validate your user program. With the help of NX Mechatronics Concept Designer (MCD) machine builders can simulate and test the mechanical components of their machine in a virtual environment. The behavior of active components, such as drives or valves is modeled in the simulation software SIMIT: Field devices of the real machinery are emulated within the SIMIT Unit. This combination helps you for preparation and for a smooth commissioning. Furthermore you can test the mechanical concept of the machine, the interplay between mechanic, electric and software as well as your user program in a very early development status of your machinery.

Advantages of the application example
  • Introduction to virtual commissioning using hardware in the loop.

  • Demonstration of the couplings and interactions between the different hardware and software components

  • Example project for each and every software component, that can serve as a template for own applications
