Honeywell 05701-A-0361  离散输入/输出模块PLC

当学习05701-A-0361编程的基础时，就像打开和关闭开关一样简单。这就是离散和模拟I/O模块的主要区别！离散信号只是简单的开或关，而模拟信号则不同。

PLC负责从输入信号中收集数据，并通过输出信号将信息发送到控制设备，以执行特定的功能。根据应用或设备，PLC程序员必须决定是使用离散还是模拟I/O。

学习PLC编程的基础知识时，有必要对输入和输出以及离散和模拟I/O模块之间的主要区别有一个基本的了解。继续阅读，对这两种机制有更深入的了解。

 05704-A-0145如果你是PLC培训的新手，I/O是技术人员中广泛使用的术语，代表“输入/输出”I/O是信息处理系统和外部世界之间的通信。输入是系统接收的信号或数据，输出是系统发出的信号。

考虑I/O的一个最简单的方法是以你的计算机为例。你的电脑是一个信息处理系统，用户是“外界”。计算机的输入是接收用户命令的键盘和鼠标，而输出是显示器和打印机。当你想到PLC时，你应该注意到PLC由两个基本部分组成:中央处理器(CPU)和I/O接口系统。I/O是连接信息处理系统(CPU)和外部世界的东西，比如机器和人机界面(HMI)。输入模块检测输入信号的状态，如按钮、开关和传感器。输出模块控制电机、继电器和灯等设备。

When learning the basics of programming 05701-A-0361, it's as simple as turning on and off a switch. This is the main difference between discrete and analog I/O modules! Discrete signals are simply on or off, whereas analog signals are different.

The PLC is responsible for collecting data from the input signal and sending the information through the output signal to the control device to perform a specific function. Depending on the application or device, the PLC programmer must decide whether to use discrete or analog I/O.

When learning the basics of PLC programming, it is necessary to have a basic understanding of the major differences between input and output and discrete and analog I/O modules. Read on to get a deeper understanding of both mechanisms.

05704-A-0145 If you are new to PLC training, I/O is a term widely used among technicians and stands for "input/output" I/O is the communication between the information processing system and the outside world. The input is the signal or data received by the system, and the output is the signal sent by the system.

One of the easiest ways to think about I/O is with your computer. Your computer is an information processing system, and the user is the "outside world." The inputs to a computer are the keyboard and mouse that receive user commands, while the outputs are the monitor and printer. When you think of a PLC, you should note that a PLC consists of two basic parts: the central processing unit (CPU) and the I/O interface system. I/O is what connects the information processing system (CPU) to the outside world, such as machines and human machine interfaces (HMI). The input module detects the status of input signals, such as buttons, switches, and sensors. The output module controls devices such as motors, relays and lights.
