跳轉(zhuǎn)到概述 應(yīng)用 功能 技術(shù)規(guī)范 更多信息 概述- 為CPU的本機(jī)I/O提供更多的數(shù)字量輸入
- 用于使控制器靈活地適應(yīng)相關(guān)任務(wù)的要求
- 用于使用附加輸入對系統(tǒng)進(jìn)行后續(xù)擴(kuò)展
應(yīng)用數(shù)字量輸入模塊允許將控制器與過程中的數(shù)字信號連接。 這為用戶提供了下列優(yōu)勢： - 適應(yīng)性：
使用可以根據(jù)需要混合的信號模塊，用戶可以使其控制器準(zhǔn)確地滿足相關(guān)任務(wù)的要求。這可以避免產(chǎn)生不必要的投資?？梢允褂脦в?8 個、16 個和 32 個輸入/輸出通道的模塊。 - 靈活性：
如果任務(wù)后續(xù)有所擴(kuò)展，可以升級控制器。更新用戶程序非常簡單。
功能SM 1221 數(shù)字量輸入信號模塊將過程中的外部數(shù)字信號電平轉(zhuǎn)換為 S7-1200 的內(nèi)部信號電平。
