現(xiàn)場(chǎng)總線安全儀表系統(tǒng)也是當(dāng)前現(xiàn)場(chǎng)總線技術(shù)的一個(gè)發(fā)展新方向。
Because traditional safety instrumented system (SIS) is not in the same layer as process control system, it is certainly that they are independent with each other in application.
由于傳統(tǒng)的安全儀表系統(tǒng)和過(guò)程控制系統(tǒng)處于不同的安全保護(hù)層面上，二者在實(shí)際應(yīng)用的過(guò)程當(dāng)中也是相互獨(dú)立的。
Basic method for determining the grades of safety instrumented system in design as well as the main process and methods for implementation and verification are introduced as well.
介紹了設(shè)計(jì)過(guò)程中的安全儀表系統(tǒng)等級(jí)確定的基本方法及實(shí)施驗(yàn)證的主要過(guò)程和方法。
