HMI是人機(jī)界面的簡(jiǎn)寫(xiě)，它為PLC控制系統(tǒng)、I/O或者其他控制系統(tǒng)提供一個(gè)人性化的操作界面，而人機(jī)界面則通過(guò)RS232、485、MODBUS、CAN總線等協(xié)議與這些控制系統(tǒng)交互數(shù)據(jù)與控制信號(hào)。由于這種交互是實(shí)時(shí)的，這就使得HMI(人機(jī)界面)實(shí)現(xiàn)了下面的關(guān)鍵功能：

1、實(shí)時(shí)監(jiān)控PLC、I/O的運(yùn)行，并在HMI上形象地顯示出來(lái);

2、操作者可以通過(guò)HMI向自動(dòng)化設(shè)備發(fā)出控制信號(hào)，使得自動(dòng)化設(shè)備可以按照操縱者的意圖運(yùn)行。

人機(jī)界面(HMI)的應(yīng)用域決定了它必須具備下列特性：

1. 人機(jī)界面(HMI)必須具備和各種自控設(shè)備交互數(shù)據(jù)的能力，這需要HMI集成各種型號(hào)的PLC、I/O、各種總線協(xié)議等自控設(shè)備的通信協(xié)議;

2. 人機(jī)界面(HMI)應(yīng)該提供一個(gè)工具軟件，供客戶開(kāi)發(fā)基于特定控制系統(tǒng)定制相應(yīng)的應(yīng)用;

3. 人機(jī)界面(HMI)必須是工業(yè)的產(chǎn)品，能夠適應(yīng)工業(yè)應(yīng)用環(huán)境，具有可靠的質(zhì)量和的性能。
