For the issue that traditional PLC simulation software can not really simulate motion scenes, in order to allow the PLC program can run in the scene intuitively, and the program is compiled to avoid inadvertently causing the actual operation of the collision, we use a combination of simulation software EON and VC + +, build a simulation platform to make compiled program shown in real time simulation system. It achieves interactive control of EON and VC + +. By writing the industry VGA car program, comparing the results out of the simulation program to verify the practicality of the platform. The results show that it is also applicable to larger and more complex systems.
