Abstract: the design of Siemens S7200 timer switch control system, through the V4.0 STEP 7 MicroWIN SP6 ladder diagram. The display using the seven LED digital tube display, access a total of 4, from left to right respectively represent a ten minutes, minutes, hours a bit, hour ten, because the display number, so that the use of dynamic display mode, the output type PLC display for the transistor source output (positive logic) display, to realize the electric timer switch output through PLC. Timing switch current control system is widely used in factories, stations, docks, theater, office, school, family and other fields. Therefore the design of multiple electric functions with display system with a timing switch
