PLC模塊是構(gòu)成可編程邏輯控制器（Programmable Logic Controller, PLC）系統(tǒng)的核心硬件單元，用于實(shí)現(xiàn)工業(yè)自動(dòng)化中的邏輯控制、數(shù)據(jù)采集與設(shè)備驅(qū)動(dòng)等功能?。它通常以“模塊化”形式存在，可根據(jù)控制需求靈活配置和擴(kuò)展，廣泛應(yīng)用于汽車(chē)制造、能源化工、機(jī)械加工等工業(yè)場(chǎng)景。

PLC系統(tǒng)由多個(gè)功能模塊協(xié)同工作，主要包含以下幾類(lèi)：

?CPU模塊?
作為PLC的“大腦”，負(fù)責(zé)執(zhí)行用戶程序、處理輸入信號(hào)并生成輸出控制指令。其性能直接影響系統(tǒng)的運(yùn)算速度與響應(yīng)實(shí)時(shí)性。

?輸入/輸出（I/O）模塊?
是PLC與外部設(shè)備的接口橋梁：

?數(shù)字量輸入（DI）/輸出（DO）模塊?：處理開(kāi)關(guān)信號(hào)，如按鈕、繼電器狀態(tài)。

?模擬量輸入（AI）/輸出（AO）模塊?：處理連續(xù)信號(hào)，如溫度、壓力傳感器數(shù)據(jù)（4-20mA或0-10V）。

特殊I/O模塊：如熱電偶、高速計(jì)數(shù)等專用模塊。

?電源模塊?
為整個(gè)PLC系統(tǒng)提供穩(wěn)定的工作電源，通常將交流電轉(zhuǎn)換為直流電（如24VDC），部分還為傳感器供電。

?通信模塊?
支持Modbus、PROFINET、EtherNet/IP等工業(yè)通信協(xié)議，實(shí)現(xiàn)PLC與上位機(jī)、HMI、伺服系統(tǒng)或其他PLC之間的數(shù)據(jù)交互。

?功能擴(kuò)展模塊?
如溫度控制模塊（如三菱Q64TCTT）、運(yùn)動(dòng)控制模塊等，滿足特定工藝需求。
