工程师们只需利用数字 I/O 和少量的模拟I/O 数以及简单的编程技巧就可开发出 80%的工业应用. PLC 已经广泛的应用在所有的工业部门。工程师在开发这些 20%的应用需要有更高的循环速率。
PLC在冰蓄冷中央空调系统控制中的应用-中文翻译Tag内容描述：
1、中文文献PLC 在冰蓄冷中央空调系统控制中的应用1 引言 在 PLC 被开发出来的三十年里，它经过不断地发展，已经能结合模拟 I/O，网络通信以及采用新的编程标准如 IEC 61131-3。然而，工程师们只需利用数字 I/O 和少量的模拟I/O 数以及简单的编程技巧就可开发出 80%的工业应用. PLC 已经广泛的应用在所有的工业部门。据“美国市场信息”的世界 PLC 以及软件市场报告称，1995 年全球 PLC 及其软件的市场经济规模约 50 亿美元5。随着电子技术和计算机技术的发展，PLC 的功能得到大大的增强由于采用传统的工具可以解决 80%的工业应用，这样就强。

4、PLC in the ice storage central air-conditioning system of control1 Introduction In PLC in 30 years which developed, it passes through develops unceasingly, already could unify simulates I/O, the network corresponds as well as uses new programming standard like IEC 61131-3. However, engineers only must use digital I/O and few simulations I/O number as well as simple programming skill on potential 80% industrial application. PLC has been widely used in all industrial sectors. According to "。
