Development of Virtual PLC Emulator |
| Abstract |
The purpose of our study is to develop tool kits which give us inexpensive simulation method. We develop a Programmable Logic Controller(PLC) program module with which we can edit and monitor PLC program, a virtual PLC(VPLC) system and simulation equipment. The PLC and simulation equipment are interlinked each other and controlled by the PLC program in real time. So, we can get effect as actual operation. Using our new tool kits, we don"t have to prepare PLC and machine, because we can configure PLC system and see the response of virtual machine in monitor. For validity of the developed program, we make experiments for the PLC program of elevator and automatic material weighing system. The experimental results show that the virtual machine(VM) operates properly by the PLC control program. |
