Master thesis presentation - Testing and evaluation of virtual commissioning
Presented by Oscar Johansson, MPSYS
A big challenge in industry is to efficiently validate industrial control code. There are a number of ways to do this and this project investigates the feasibility of using Dassault Systèmes 3DExperience to carry out a Virtual Commissioning. This is done by creating a virtual replica of an existing manufacturing cell, producing cog wheels, at Scania. A 3D model is created in 3DExperience and then connected via the OPC protocol to be controlled by a simulated Siemens PLC.
It is concluded that it is possible to carry out such a project with this software tool but some modifications to the programs in the cell was needed. The existing robot program were too advanced to be handled by the Delmia translator and could not be imported. The PLC program was functional with the addition of an open source add-on making it possible to communicate via OPC and an extra code block to remap the signals to the correct address.
In order to simulate the robot movements, the targets and speed/acceleration paramters were imported from the robot program. All movements of the robot had to be re-programmed in Delmia.
Suggestions for how to construct robot- and PLC programs in order to work with this software is presented as well as suggestions for improvements in the software.
