NW-BM85C002 控制器將生成反饋信息并用Modbus協(xié)議發(fā)出

Modbus是一種串行通信協(xié)議，廣泛應(yīng)用于工業(yè)自動(dòng)化領(lǐng)域。它最初由Modicon公司（現(xiàn)在的施耐德電氣 Schneider Electric）于1979年為使用可編程邏輯控制器（PLC）通信而發(fā)表。Modbus已經(jīng)成為工業(yè)領(lǐng)域通信協(xié)議的業(yè)界標(biāo)準(zhǔn)，并且現(xiàn)在是工業(yè)電子設(shè)備之間常用的連接方式。

Modbus協(xié)議定義了一個(gè)控制器能認(rèn)識(shí)使用的消息結(jié)構(gòu)，而不管它們是經(jīng)過何種網(wǎng)絡(luò)進(jìn)行通信的。NW-BM85C002描述了一控制器請(qǐng)求訪問其它設(shè)備的過程，如果回應(yīng)來自其它設(shè)備的請(qǐng)求，以及怎樣偵測(cè)錯(cuò)誤并記錄。它制定了消息域格局和內(nèi)容的公共格式。當(dāng)在一個(gè)Modbus網(wǎng)絡(luò)上通信時(shí)，此協(xié)議決定了每個(gè)控制器須要知道它們的設(shè)備地址，識(shí)別按地址發(fā)來的消息，決定要產(chǎn)生何種行動(dòng)。如果需要回應(yīng)，控制器將生成反饋信息并用Modbus協(xié)議發(fā)出。

Modbus協(xié)議目前存在用于串口、以太網(wǎng)以及其他支持互聯(lián)網(wǎng)協(xié)議的網(wǎng)絡(luò)的版本?；诖谕ㄐ?，存在兩個(gè)變種，即RTU和ASCII兩種通信模式。此外，Modbus協(xié)議采用主從架構(gòu)，其中只有一個(gè)主設(shè)備，可以有1-247個(gè)從設(shè)備。主設(shè)備通過特定的地址與從設(shè)備進(jìn)行通信。

總之，Modbus是一種廣泛應(yīng)用于工業(yè)自動(dòng)化領(lǐng)域的串行通信協(xié)議。NW-BM85C002具有開放性、通用性和靈活性等特點(diǎn)，能夠?qū)崿F(xiàn)不同廠商生產(chǎn)的控制設(shè)備之間的互連互通，提高工業(yè)自動(dòng)化系統(tǒng)的可靠性和穩(wěn)定性。

NW-BM85C002 控制器將生成反饋信息并用Modbus協(xié)議發(fā)出

Modbus is a serial communication protocol, widely used in the field of industrial automation. It was originally published by Modicon Corporation (now Schneider Electric) in 1979 for communication using programmable logic controllers (PLCS). Modbus has become the industry standard for communication protocols in the industrial sector and is now a common way of connecting industrial electronic devices.

The Modbus protocol defines a message structure that a controller understands to be used, regardless of the network over which they communicate. NW-BM85C002 describes how a controller requests access to other devices, if it responds to requests from other devices, and how errors are detected and logged. It establishes a common format for message domain schema and content. When communicating over a Modbus network, this protocol determines that each controller needs to know their device address, recognize messages sent by address, and decide what action to take. If a response is required, the controller generates a feedback message and sends it out using Modbus protocol.

The Modbus protocol currently exists in versions for serial ports, Ethernet, and other networks that support Internet protocols. Based on serial communication, there are two variants, namely RTU and ASCII two communication modes. In addition, the Modbus protocol uses a master-slave architecture, where there is only one master device and there can be 1-247 slave devices. The master device communicates with the slave device at a specific address.

In short, Modbus is a serial communication protocol widely used in the field of industrial automation. NW-BM85C002 has the features of openness, versatility, and flexibility. It can realize the interconnection between control devices produced by different manufacturers, and improve the reliability and stability of industrial automation systems.
