摘要
介绍了利用西门子S7-200PLC对三工位旋转工作台的控制,阐述了控制方案,同时根据三工位旋转工作台的控制要求和特点,确定了PLC的输入输出分配,设计出顺序功能图和梯形图。
The paper introduces the PLC control of three-station rotary tables by the use of Siemens S7-200PLC and puts forward the control programs. Meanwhile, based on the control requirements and characteristics of three-station rotary tables, the PLC distribution of input and output is determined, and the Sequential Function Chart （SFC） and Ladder Diagram（LAD） are designed as well.
