>>>型号:1771-WA 输入输出模块 用于工业自动化和控制系统 具有高度的可靠性和稳定性
【功能描述】
1771-WA是一款PLC（可编程逻辑控制器）输入输出模块。这款模块是工业自动化控制系统中的重要组成部分，用于连接和控制各种工业设备。
1771-WA模块具有SPI4.2接口，该接口分为数据通道和状态通道。数据通道多分成256个逻辑通道，采用LVDS信号电平，按照cell格式传送数据。每个cell都是以控制字开始的，控制字包含逻辑端口号、报文起始标志位、
报文结束标志位、控制字交验等信息。状态通道则用于传输对端的状态信息。
1771-WA模块可以根据控制系统的需求进行配置，实现数据的采集、处理和控制逻辑的执行。它通常与其他AB罗克韦尔PLC模块以及人机界面、传感器和执行器等设备配合使用，共同构建完整的工业自动化系统。
该模块具有高度的可靠性和稳定性，能够在恶劣的工业环境下长时间稳定运行。同时，它还支持热插拔功能，方便在不停机的情况下进行模块的更换和维护。此外，1771-WA模块还提供了丰富的诊断和故障指示功能，
有助于及时定位和解决潜在问题。

【英文介绍】
The 1771-WA is a PLC (Programmable Logic Controller) input/output module. This module is an important part of the industrial automation control system, used to connect and control various industrial equipment.
The 1771-WA module has SPI4.2 interface, which is divided into data channel and status channel. The data channel is divided into 256 logical channels, which use LVDS signal level to transmit data in cell format.
Each cell starts with a control word. The control word contains the logical port number, packet start flag bit, packet end flag bit, and control word check. The status channel transmits the status information of the peer end.
The 1771-WA module can be configured according to the requirements of the control system to achieve data acquisition, processing and control logic execution. It is often used in conjunction with other AB Rockwell
PLC modules as well as devices such as human machine interfaces, sensors and actuators to build complete industrial automation systems.
The module has a high degree of reliability and stability, and can operate stably in harsh industrial environments for a long time. At the same time, it also supports the hot swap function, which facilitates the replacement
and maintenance of the module without stopping. In addition, the 1771-WA module provides a wealth of diagnostic and fault indication capabilities to help locate and resolve potential problems in a timely manner.
