1785-L60B/E

目前，随着大规模和超大规模集成电路等微电子技术的发展，PLC已由最初一位机发展到现在的以16位和32位微处理器构成的微机化PC，而且实现了多处理器的多通道处理。如今，PLC技术已非常成熟，不仅控制功能增强，功耗和体积减小，成本下降，可靠性提高，编程和故障检测更为灵活方便，而且随着远程I/O和通信网络、数据处理以及图象显示的发展，使PLC向用于连续生产过程控制的方向发展，成为实现工业生产自动化的一大支柱。现在，世界上有200多家PLC生产厂家，400多品种的PLC产品，按地域可分成美国、欧洲、和日本等三个流派产品，各流派PLC产品都各具特色。其中，美国是PLC生产大国，有100多家PLC厂商，著名的有A-B公司、通用电气（GE）公司、莫迪康（MODICON）公司。欧洲PLC产品主要制造商有德国的西门子（SIEMENS）公司、AEG公司、法国的TE公司。日本有许多PLC制造商，如三菱、欧姆龙、松下、富士等，韩国的三星（SAMSUNG）、LG等，这些生产厂家的产品占有80%以上的PLC市场份额。

经过多年的发展，国内PLC生产厂家约有三十家，国内PLC应用市场仍然以国外产品为主。国内公司在开展PLC业务时有较大的竞争优势，如：需求优势、产品定制优势、成本优势、服务优势、响应速度优势。在产品规模方面，向两极发展。一方面，大力发展速度更快、性价比更高的小型和超小型PLC。以适应单机及小型自动控制的需要。另一方面，向高速度、大容量、技术完善的大型PLC方向发展。随着复杂系统控制的要求越来越高和微处理器与计算机技术的不断发展，人们对PLC的信息处理速度要求也越来越高，要求用户存储器容量也越来越大。
