关于 PLC 消亡的传言,可能大大地被夸张了。可编程序控制器(PLC)作为工厂控制的基础至今已有30年,但几年前,PLC 与PC 的战线已经拉开。少数工程师考虑了PC 应用于生产控制,因为 PC 的图形显示和数据处理功能强,但存在有“蓝屏死机”的潜在危险,使负责保持生产线运行的人有所恐惧。
Rumors about the demise of PLC may have been greatly exaggerated. PLCs have been the foundation of plant control for 30 years now, but a few years ago PLCs and PCs had opened up. A handful of engineers considered the use of PCs for production control because of the powerful graphical display and data processing capabilities of the PC, but the potential danger of a “blue screen of death” that fears those responsible for keeping the production line running.
