Through the production of tile manufacturing process overall analysis and transmission of suppressing tiles, dust overturned transmission to fight dryer imported specific analysis, drawn S7-200 PLC application control function better. S7-200 PLC automatic control procedure adopted by the objective to improve ease of updating, solve the relay control only for the scene, inconvenience improvement. According to production needs and S7-200 PLC to the characteristics of specific analysis of the entire process, come to a specific set of control points, and the monitoring of the relationship between point, in order to determine I/O points. According I/O points, CPU and expansion slot selection; According to the scene, configure motor type and type, Drawing electrical connection graph. According to the transmission requirements for the design ladder; The entire slabs can suppress the output line security, stability of the tiles will be transmitted to dryer. Feedback reflex switches;
Switching ;I/O proliferation feedback interface;
