AO801模拟量输出模块并非直接称为“通讯模块”，但它确实与通信和接口有关。以下是关于AO801模拟量输出模块的一些关键信息：

1. 功能与特点：AO801模拟量输出模块具有8个单极性模拟输出通道，通常用于AC500CPU的本地扩展模块，与接口模块如DC505-FBP/DC551-CS31组合使用，实现分布式扩展。它支持0/4-20mA或0/4-20mA的电流输出，具有短路保护和模拟输出OSP（输出状态保护）功能，能在检测到错误时将输出设置为预定状态。
2. I/O模块集成：AO801模拟量输出模块集成了PLC（可编程逻辑控制器）的I/O电路。输入暂存器反映输入信号状态，而输出点反映输出锁存器状态。在模拟量输出的情况下，该模块将数字信号转换为模拟信号（如电流）输出。
3. 应用场景：AO801模拟量输出模块常用于工业自动化系统中，与各种传感器和执行器配合，实现连续变化的物理量的测量和控制，如温度、压力、流量等。

虽然AO801本身不是直接用于通信的模块，但它作为PLC系统的一部分，可以通过与其他通信模块或设备的配合，实现与上位机、其他PLC或远程监控系统的通信。这样，AO801模拟量输出模块可以将采集到的模拟信号转换为数字信号，并通过通信接口发送给上位机或其他设备，实现数据的远程监控和控制。

ABB AO801 Analog Communication Module Details Introduction:

The AO801 analog output module is not directly referred to as a "communication module," but it is indeed related to communication and interfaces. Here are some key information about the AO801 analog output module:

Function and characteristics: The AO801 analog output module has 8 unipolar analog output channels and is usually used as a local expansion module for AC500 CPUs. It is combined with interface modules such as DC505-FBP/DC551-CS31 to achieve distributed expansion. It supports current output of 0/4-20mA or 0/4-20mA, with short-circuit protection and analog output OSP (output state protection) function, and can set the output to a predetermined state when an error is detected.

I/O module integration: The AO801 analog output module integrates the I/O circuit of a PLC (Programmable Logic Controller). The input register reflects the state of the input signal, while the output point reflects the state of the output latch. In the case of analog output, this module converts digital signals into analog signals (such as current) for output.

Application scenario: The AO801 analog output module is commonly used in industrial automation systems, in conjunction with various sensors and actuators, to achieve continuous measurement and control of physical quantities such as temperature, pressure, flow rate, etc.

Although AO801 itself is not a module directly used for communication, as a part of the PLC system, it can achieve communication with the upper computer, other PLCs, or remote monitoring systems by cooperating with other communication modules or devices. In this way, the AO801 analog output module can convert the collected analog signals into digital signals and send them to the upper computer or other devices through communication interfaces, achieving remote monitoring and control of data
