:西寧2098-DSD-HV030 AB伺服驅(qū)動(dòng)器 羅克韋爾哪里好dcs作為大型控制系統(tǒng)，它采用的通信方式無(wú)非就是數(shù)字通信和模擬通信。數(shù)字通信它在DCS使用就是在監(jiān)視層和層。而模擬通信的應(yīng)用在現(xiàn)場(chǎng)控制層和數(shù)據(jù)檢測(cè)層。根據(jù)上述提到，實(shí)際上DCS控制站以上是以數(shù)字通信實(shí)現(xiàn)，而控制站以下是以模擬量實(shí)現(xiàn)，DCS系統(tǒng)和現(xiàn)場(chǎng)的變送器、執(zhí)行器等現(xiàn)場(chǎng)儀表之間都是以4-20mA模擬通信方式進(jìn)行信號(hào)傳遞。雖然DCS采用兩種通信方式，但是模擬通信方式相比數(shù)字通信方式還是較明顯處于劣勢(shì)一方。
