國產(chǎn)PLC可編程控制器控制系統解決方案 USC-8000 硬件-設計丨龍鼎源

Publication At: 2024-03-02
View: 27909

USC-8000 面向安全設計


安全狀態(tài)定義:控制器IOBUS靜默、DI/AI上報0、DO不輸出、AO輸出0mA

核心設計:1oo2架構可以在單故障下執行安全功能

關(guān)鍵設計:針對故障的診斷,對失效的處理

通信設計:用于連接控制器和IO模塊的IOBUS

工程軟件:針對功能安全的反編譯和對比

認證邊界:控制器、IO模塊、 IOBUS 、Workbench

可靠性:針對功能安全是高可靠的,常規應用下的可靠性指標不能直接引用功能安全分析的結果

檢修要求:一年一次,目的是對DU(不可診斷危險失效)進(jìn)行測試。


USC-8000 面向非安全設計


背景:安全和非安全混合在一起使用的情況下,安全對于非安全的應用有各種限制,例如:故障后輸出的狀態(tài)、輸入接線(xiàn)、寫(xiě)控制器內部變量等。

實(shí)現:基于通信板卡

數據中心:實(shí)現不同數據的匯集和交換。

邊緣計算(開(kāi)發(fā)中):采用高級語(yǔ)言對數據進(jìn)行邊緣處理,python。

可編程控制(開(kāi)發(fā)中):常規PLC

可編程網(wǎng)關(guān)(開(kāi)發(fā)中):不同協(xié)議實(shí)現數據交換,并且對數據進(jìn)行處理,比如:bit合并,數值縮放等。
