摘要
PLC不但能进行逻辑运算,还能进行数据处理,一个运行良好的中大型程序,它的数据处理一定做得近乎完美。近年来,大家把对后者的重视程度逐步提高到了一个新的高度。要更好的掌握好S7-1200PLC的编程技术,难度最大的还是在程序中的数据处理部分,对数据的存储形式的理解则是提高工程技术人员驾驭程序能力的基础,值得大家深入研究。
PLC can not only perform logic operations,but also data processing,a well-run medium and large program,its data processing must be almost perfect.In recent years,people have gradually raised the importance of the latter to a new height.To better master the programming technology of S7-1200 PLC,the most difficult part is in the data processing part of the program.The understanding of the storage form of data is the basis for improving the ability of engineers and technicians to control the program.It is worth in-depth study.
