The special circumstances of the special machines. Its core technology for long-term foreign monopoly. According to the characteristics of the electrolyte cleaning machine, a manual clean-up of a simulation of a single charcoal electrolyte cleaning machine design on the status of the electrolyte cleaning machine, the configuration on the basis of the argument similar machine, the electrolyte cleaning machine has a new understanding, through the control system the main circuit, control circuit design and parameter calculation are given complete control system for control of electrical schematics and flowcharts. According to the requirements of the anode assembly of the production process, the design and prepared a PLC control software in the assembly process with STEP 7. Involved in the design process more switch input and output points, so selection of the configuration of a flexible, modular structure PLC in order to improve system reliability and processing efficiency. The design of the electrolyte cleaning machine, automatic and manual control is divided into two control processes, which move the speed of the motor drive control.In the control program, select the PLC Siemens S7-200 series programmable controller, CPU and host selection of the CPU226. Programming and simulation software to simulate the corresponding control process.Keywords: PLC; electr
