機型選擇的其他考慮：在考慮上述性能后，還要根據(jù)工程應用實際考慮其他
些因素包括：
a. 性能價格比。毫無疑問，高性能的機型必然需要較高的價格。在考慮滿足需要的性能后，還要根據(jù)工程的投資狀況來確定選型。
b. 備品備件。無論什么樣的設備，投入生產后都要具有 定數(shù)量的備品備件。在系統(tǒng)硬件設計時，對于 個工廠來說應盡量與原有的設備統(tǒng) 機型，這樣 來就可以減少備品備件的種類和資金積壓。同時還要考慮備品備件的來源，所選機型要有可靠的定貨來源。
c. 技術支持。 選擇機型時還要考慮有可靠的技術支持。這些支持包括必要的技術培訓、設計指導、系統(tǒng)維修等內容。
4. 輸入/輸出模塊的選擇
可編程控制器與工業(yè)生產過程的聯(lián)系是通過各種I/O模塊實現(xiàn)的。通過I/O接口模塊，可編程控制器檢測到所需的過程信息，并將處理結果傳送給外部過程，驅動各種執(zhí)行機構，實現(xiàn)工業(yè)生產過程的控制。在可編程控制器構成的控制系統(tǒng)中，需要 多的就是各種I/O模塊。為了適應各種各樣的過程信號，相應地有許多種I/O模塊。它們包括數(shù)字量輸入/輸出模塊、模擬量輸入/輸出模塊、各種通眩塊。本書將從應用角度出發(fā)，討論各種I/O模塊的選擇原則及注意事項。
