(產(chǎn)品的性能)

為了進一步提高可編程邏輯控制器的可靠性

對大型可編程邏輯控制器還采用雙CPU構成冗余系統(tǒng)，或采用三CPU的表決式系統(tǒng)。這樣，即使某個CPU出現(xiàn)故障，整個系統(tǒng)仍能正常運行。

存放系統(tǒng)軟件的存儲器稱為系統(tǒng)程序存儲器。 存放應用軟件的存儲器稱為用戶程序存儲器。
(產(chǎn)品的優(yōu)點)

輸入輸出接口電路

1．現(xiàn)場輸入接口電路由光耦合電路和微機的輸入接口電路，作用是可編程邏輯控制器與現(xiàn)場控制的接口界面的輸入通道。2．現(xiàn)場輸出接口電路由輸出數(shù)據(jù)寄存器、選通電路和中斷請求電路集成，作用可編程邏輯控制器通過現(xiàn)場輸出接口電路向現(xiàn)場的執(zhí)行部件輸出相應的控制信號。功能模塊 如計數(shù)、定位等功能模塊。 通信模塊

(產(chǎn)品的用途)

在輸入采樣階段

可編程邏輯控制器以掃描方式依次地讀入所有輸入狀態(tài)和數(shù)據(jù)，并將它們存入I/O映象區(qū)中的相應的單元內(nèi)。輸入采樣結(jié)束后，轉(zhuǎn)入用戶程序執(zhí)行和輸出刷新階段。在這兩個階段中，即使輸入狀態(tài)和數(shù)據(jù)發(fā)生變化，I/O映象區(qū)中的相應單元的狀態(tài)和數(shù)據(jù)也不會改變。因此，如果輸入是脈沖信號，則該脈沖信號的寬度必須大于一個掃描周期，才能保證在任何情況下，該輸入均能被讀入。
