SIMATIC S7-1500T - Virtual commissioning for kinematics in NX MCD with Software in the Loop

  • Entry
  • Associated product(s)
The NX Mechatronics Concept Designer (MCD) allows you to model and simulate the mechanical and electrical components of your machine. With the "Kinematics Toolbox" you get a NX reuse library for fast implementation of kinematics into your NX MCD machine design.

The MCD extends the classical CAD design functions of NX by a realistic simulation environment in which the effect of physical forces on moving objects can be mapped. With a functional model of the machine, the digital twin, you have the possibility to virtually test the machine behavior with your original control program.

"Kinematics Toolbox"
To accelerate and standardize the development of NX MCD machine models, you can use NX reuse libraries. With the "Kinematics Toolbox" you get an NX reuse library that contains parameterizable NX MCD models for kinematics. The following kinematics types of the SIMATIC S7-1500 T-CPU are included in the Kinematics Toolbox

  • Cartesian portal 3D with orientation
  • Roller picker 3D with orientation (vertical)
  • 3D articulated arm with orientation
  • Delta-Picker 3D with orientation
  • Scara 3D with orientation
  • Cylindrical 3D robot with orientation
  • Tripod 3D with orientation

Software in the Loop
This application example describes a Software in the Loop (SiL) solution for SIMATIC S7-1500 T-CPUs. No hardware is required for virtual commissioning. You simulate your original control project of the SIMATIC S7-1500 T-CPU on a virtual CPU with PLCSIM Advanced. The signals of the NX MCD models are coupled to the virtual CPU. 


Application variants of the Kinematics Toolbox
In this application example you get four different application variants to perform virtual commissioning with the MCD models of the "Kinematics Toolbox".

Application variants 3 and 4 are in preparation.
