Designed the PLC control system a total project in according to the PLC static cutting the machine control system design, give soft, hardware design and carry out a project. Design part in the hardware, elaborate the design process of the electric motor main electric circuit and its electric appliances control electric circuit, gave the choice of these two electric appliances components of electric circuits the result. Be controlling the design part of the electric circuit, elaborate I/O to connect the design process of the line diagram, give the PLC and the choice of its input/output component the result. Design the design process that the part elaborated the PLC customer procedure in detail in the software, include among them to the public procedure, hand to move the design process that the procedure, automatic procedure and give alarm signal procedure to elaborate, and gave above-mentioned all trapezoid diagrams of procedures and th
