83SR04C-E模块备件使用区域

80年代后期到90年代中期，随着计算机和网络技术的普及应用，超大规模集成电路、门阵列以及集成电路的迅速发展，可编程序控制器的CPU已发展为由16位或32位微处理器构成，处理速度得到很大提高，高速计数、中断、PID、运动控制等功能引入了可编程序控制器。使得可编程序控制器能够满足工业生产过程的各个领域，可编程序控制器已完全取代了传统的逻辑控制装置，模拟量仪表控制装置和以小型机为核心的DDC（直接数字控制）控制装置。由于联网能力增强，既可和上位计算机联网，也可以下挂 FLEX I/O 或远程 I/O ，从而组成分布式控制系统（DCS）已无困难。梯型图语言和语句表语言完全成熟，基本上标准化，SFC（顺序功能图）语言逐步普及，的编程器已被个人计算机和相应编程软件所替代，人机界面装置日趋完善，已能进行对整个工厂的监控、管理，并发展了冗余技术，大大加强了可靠性。

From the late 1980s to the mid-1990s, with the popularization and application of computer and network technology and the rapid development of VLSI, gate array and integrated circuit, the CPU of the programmable controller has been developed into a 16 bit or 32-bit microprocessor, and the processing speed has been greatly improved. The functions of high-speed counting, interrupt, PID, motion control and so on have been introduced into the programmable controller. The programmable controller can meet all fields of industrial production process. The programmable controller has completely replaced the traditional logic control device, analog instrument control device and DDC (direct digital control) control device with minicomputer as the core. Due to the enhanced networking ability, it can be networked with the upper computer, and can also be connected with flex i/o or remote i/o, so it is no longer difficult to form a distributed control system (DCS). Ladder diagram language and statement table language are completely mature and basically standardized. SFC (sequential function diagram) language is gradually popularized. The programmer of has been replaced by personal computer and corresponding programming software. The man-machine interface device is becoming more and more perfect. It has been able to monitor and manage the whole plant, and has developed redundant technology, which greatly enhances the reliability.
