【 摘 要 】

Many CAD programs allows the simulation of machines. Often, before creating the real machine can simulate the operation and see how it works. In these cases, set values of the forces acting on an element or displacement of the element. It is very easy for simple machines. Programming in this way PLC controlled system is very complicated because have to save the the entire PLC logic in the simulation program. It would be good simply connect the PLC or PLC simulation program to a CAD program enabling the simulation. There are many possibilities for sending information between the PLC and CAD. PLC to control most of the actuators using the digital outputs 0 or 1. Actuators often have two states but the transition from one to the other takes some time. By setting additional parameters may be the behaviour of the simulation as in real life. Setting these parameters is usually held in the testing phase before running it means that the system is assembled and can be damaged. Often this is the only opportunity to verify the PLC program. It is worth noting that such testing and running takes place on the production line and needs to be stopped.
