摘要
本文结合PLC的发展,比较了PLC编程方式与计算机编程的相似点,并将计算机编程中数据库概念和程序嵌套思想应用到PLC编程过程中,简化了原有的电梯程序,充分利用了数据存储空间,取得了理想的编程效果。
This paper compares the similarity of programming manner between PLC and Computer,and introduces the application of computer programming idea in PLC program,which includes the application of database and program nestification in PLC program.The application simplifies the original elevator control program and sufficiently uses the memory room of PLC.Finally the elevator control system is perfectly programmed.
