在现代化的工业生产设备中，有大量的数字量及模拟量的控制装置，例如电机的启停，电磁阀的开闭，产品的计数，温度、压力、流量的设定与控制等，而PLC技术是解决上述问题的有效、便捷的工具，因此PLC在工业控制领域得到了广泛的应用。下面就PLC工业控制系统设计中的问题进行探讨。
2 PLC系统设备选型
PLC主要的目的是控制外部系统。这个系统可能是单个机器，机群或一个生产过程。不同型号的PLC有不同的适用范围。根据生产工艺要求，分析被控对象的复杂程度，进行I/O点数和I/O点的类型（数字量、模拟量等）统计，列出清单。适当进行内存容量的估计，确定适当的留有余量而不浪费资源的机型（小、中、大形机器）。并且结合市场情况，考察PLC生产厂家的产品及其售后服务、技术支持、网络通信等综合情况，选定价格性能比较好的PLC机型。
目前市场上的PLC产品众多，国外有德国的SIEMENS;日本的 OMRON、MITSUBISHI、FUJI、Panasonic;美国的GE;韩国的LG等。国产有研华、研祥、合力时等。近几年，PLC产品的价格有较大的下降，其越来越高
