F3DIO20802 采用一类可编程的存储器，用于其内部存储程序

可编程控制器（Programmable Controller）是计算机家族中的一员，F3DIO20802 是为工业控制应用而设计制造的。早期的可编程控制器称作可编程逻辑控制器（Programmable Logic Controller，PLC），它主要用来代替继电器实现逻辑控制。随着技术的发展，这种装置的功能已经大大超过了逻辑控制的范围，因此，今天这种装置称作可编程控制器，或简称PC。但是为了避免与个人计算机（Personal Computer）的简称混淆，所以将可编程控制器简称PLC。

可编程控制器是一种数字运算操作的电子系统，专为在工业环境应用而设计的。它采用一类可编程的存储器，用于其内部存储程序，执行逻辑运算、顺序控制、定时、计数与算术操作等面向用户的指令，并通过数字或模拟式输入/输出控制各种类型的机械或生产过程。

可编程控制器及其有关的外围设备都应该按易于与工业控制系统形成一个整体，易于扩展其功能的原则而设计。

The Programmable Controller is a member of the computer family and the F3DIO20802 is designed and manufactured for industrial control applications. Early Programmable controllers were called programmable Logic controllers (PLCS), which were mainly used to replace relays for logic control. With the development of technology, the function of this device has greatly exceeded the scope of logic control, so today this device is called a programmable controller, or PC. However, in order to avoid confusion with the abbreviation of Personal Computer, the programmable controller is referred to as PLC.

A programmable controller is a digital operational electronic system designed for use in an industrial environment. It uses a class of programmable memory for its internal storage programs, performs user-oriented instructions such as logical operations, sequence control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog input/output.

The programmable controller and its related peripherals should be designed in accordance with the principle that it is easy to form a whole with the industrial control system and easy to expand its function.
