Its electric control system composed of time relay, relay and transformer etc, not only the volume is big, cost is high, and installation, maintenance and trouble. Programmable controller (PLC) is a kind of special designed for industrial environment application and computer, because of its high reliability, simple programming, easy to maintain and widely used in various control systems. Configuration software is a rise in the field of industrial automation is a new type of software development technology. Developers dont need to compile the specific instructions and code, as long as using the tools in the configuration software package, through hardware configuration (hardware), data configuration, graphics configuration, etc. Work to complete the required application software development work. Configuration software is remote monitoring, data collection, data analysis and process control such as powerful function. According to the needs of industrial field programmable controller (PLC) and their own characteristics, the design of metal die-casting machine PLC control system design and configuration of simulation. In this design, this design uses the mitsu
