上一讲介绍了可编调节器的总体结构,可编程调节器是由CPU、ROM、RAM和接口电路等部件组成,我们称这些部件为硬件。为了完成对生产过程的调节和控制,仅有这些硬件是不够的,还必须有使这些硬件按照人们意志进行工作的部件,这个部件我们称之为软件。软件是由程序系统和有关信息组成的。可编程调节器装备了这些硬件和软件后,就可完成一定的调节和控制功能了。
The last talk about the overall structure of the programmable regulator, programmable regulator CPU, ROM, RAM and interface circuits and other components, we call these components for the hardware. In order to complete the process of regulation and control of the production process, only these hardware is not enough, but also have to make these hardware according to people’s will work parts, this part we call software. Software is composed of program system and related information. Programmable regulator equipped with these hardware and software, you can complete some regulation and control functions.
