描述
通訊處理器用于將 S7-400 連接到不同的總線系統(tǒng)/通訊網(wǎng)絡(luò)，也用于點(diǎn)對(duì)點(diǎn)的連接。
作為總線系統(tǒng)的替代品，借助通訊處理器 (CP) 實(shí)現(xiàn)的點(diǎn)對(duì)點(diǎn)連接功能非常強(qiáng)大且成本較低。當(dāng)僅要將幾個(gè) (RS 485) 設(shè)備連接到 SIMATIC S7 時(shí)，與總線系統(tǒng)相比，點(diǎn)對(duì)點(diǎn)鏈路的優(yōu)勢是極為明顯的。
通訊處理器也能夠輕松地將第三方系統(tǒng)連接至 SIMATIC S7-400 系統(tǒng)中。由于 CP 具有很高的靈活性，因此可以執(zhí)行不同的物理傳輸介質(zhì)、傳輸速度，甚至是自定義的傳輸協(xié)議。對(duì)每一個(gè) CP 都有一個(gè)組態(tài)包。組態(tài)包中帶有電子手冊(cè)、參數(shù)化屏幕表單和用于 CPU 和 CP 之間通訊的標(biāo)準(zhǔn)功能塊。組態(tài)數(shù)據(jù)存儲(chǔ)在系統(tǒng)塊中并在 CPU 中備份。因此，在更換模塊后，新模塊馬上就可以使用。
借助 S7-400 點(diǎn)對(duì)點(diǎn)鏈路模塊，針對(duì)不同的物理傳輸介質(zhì)，只需要插入相關(guān)的接口子模塊，而無需外部轉(zhuǎn)換器。

設(shè)計(jì)和功能
通訊處理器有堅(jiān)固的塑料外殼，結(jié)合 LED 顯示操作狀態(tài)和故障，用于表明發(fā)送、接收和錯(cuò)誤。
? 設(shè)計(jì)緊湊
? 安裝簡便
? 方便的布線等
