HX300詳細(xì)說明:
HX300有4個輸出通道。提供了12位高精度分辨率的數(shù)字輸入。轉(zhuǎn)換速度為2.1ms/4通道,使用的通道數(shù)變化不會改變轉(zhuǎn)換速度。輸出的形式可為電壓,也可為電流。其選擇取決于接線不同。電壓輸出時,兩個模擬輸出通道輸出信號為0~10V DC,0~5V DC;電流輸出時為4~20mA DC。分辨率為2.5mV(0~10V DC)和4uA(4~20mA)。數(shù)字到模擬的轉(zhuǎn)換特性可進(jìn)行調(diào)整。本模塊需占用8個I/O點(diǎn)。適用于FX1N、FX2N、FX2N子系列。其他的性能與FX2N-2DA相似。
可編程控制器基本單元與FX2N-4DA之間的數(shù)據(jù)通訊也是由FROM/TO指令來執(zhí)行的。讀寫操作是對FX2N-4DA的緩沖寄存器BFM進(jìn)行操作的,緩沖器區(qū)由32個16位的寄存器組成,編號為BFM﹟0~﹟31。
