工业控制计算机(有的称“过程计算机、工业用计算机”等)是现代工业实现综合自动化不可缺少的技术工具,它既是计算机总体系的一个重要分支,又是工业自动化仪表体系不可缺少的重要组成部分。工业控制计算机包括硬件和软件。硬件有主机、外部设备以及与被控对象相联系的过程输入输出通道设备和人一机系统设备。软件有适应工业控制的实时系统软件、通用应用软件和专用软件。近年来,工业控制计算机系统结构的演变,使控制系统任务可以分解,由处于系统中不同级或层的仪表装置来实现。系统中处于下一级的仪表装置承担所辖范围的测量控
Industrial control computers (sometimes referred to as “process computers, industrial computers, etc.”) are indispensable technical tools for modern industrial automation. They are both an important branch of the overall computer system and an indispensable component of the industrial automation instrumentation system section. Industrial control computers include hardware and software. Hardware host, external devices and the controlled object associated with the process of input and output channel devices and people-machine system equipment. Software to adapt to industrial real-time system control software, general-purpose applications and special software. In recent years, the evolution of industrial control computer system architecture has enabled control system tasks to be decomposed and implemented by instrumentation devices at different levels or layers in the system. System in the next level of instrumentation under the jurisdiction of the measurement control
