>>>型號:1771-WA 輸入輸出模塊 用于工業(yè)自動化和控制系統(tǒng) 具有高度的可靠性和穩(wěn)定性
【功能描述】
1771-WA是一款PLC（可編程邏輯控制器）輸入輸出模塊。這款模塊是工業(yè)自動化控制系統(tǒng)中的重要組成部分，用于連接和控制各種工業(yè)設(shè)備。
1771-WA模塊具有SPI4.2接口，該接口分為數(shù)據(jù)通道和狀態(tài)通道。數(shù)據(jù)通道多分成256個邏輯通道，采用LVDS信號電平，按照cell格式傳送數(shù)據(jù)。每個cell都是以控制字開始的，控制字包含邏輯端口號、報文起始標(biāo)志位、
報文結(jié)束標(biāo)志位、控制字交驗等信息。狀態(tài)通道則用于傳輸對端的狀態(tài)信息。
1771-WA模塊可以根據(jù)控制系統(tǒng)的需求進(jìn)行配置，實現(xiàn)數(shù)據(jù)的采集、處理和控制邏輯的執(zhí)行。它通常與其他AB羅克韋爾PLC模塊以及人機界面、傳感器和執(zhí)行器等設(shè)備配合使用，共同構(gòu)建完整的工業(yè)自動化系統(tǒng)。
該模塊具有高度的可靠性和穩(wěn)定性，能夠在惡劣的工業(yè)環(huán)境下長時間穩(wěn)定運行。同時，它還支持熱插拔功能，方便在不停機的情況下進(jìn)行模塊的更換和維護(hù)。此外，1771-WA模塊還提供了豐富的診斷和故障指示功能，
有助于及時定位和解決潛在問題。

【英文介紹】
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.
