Description

特别提出的是与STD总线工控机的区别，无论从维修、安装和模件功能都很相似。PLC更适用于黑模式下运行，但在线运行时若要进行较大的程序修改，其能力略逊于STD工控机，但是从开关量控制而言，PLC的性能优于STD工控机。

总的来说，在选择控制器时，首先要从工程要求、现场环境和经济性等方面考虑。没有什么控制器绝对完善，也没有哪种产品绝对差，只能说选择更适用的产品。

PLC自问世以来，经过20多年的发展，在美国、欧洲、等工业发达国家已成为重要产业，1987年世界PLC的销售额为25亿美元，此后每年以20%左右的速度递增。进入90年代以来，世界PLC的年平均销售额在55亿美元以上，其中我国约占1%。当前，PLC在国际市场上已成为最受欢迎的工业控制畅销产品，用PLC设计自动控制系统已成为世界潮流。
