A80L-0001-0272經(jīng)濟性的考慮
選擇PLC時，應考慮性能價格比?？紤]經(jīng)濟性時，應同時考慮應用的可擴展性、可操作性、投入產(chǎn)出比等因素，進行比較和兼顧，最終選出較滿意的產(chǎn)品。
輸入輸出點數(shù)對價格有直接影響。每增加一塊輸入輸出卡件就需增加一定的費用。當點數(shù)增加到某一數(shù)值后，相應的存儲器容量、機架、母板等也要相應增加，因此，點數(shù)的增加對CPU選用、存儲器容量、控制功能范圍等選擇都有影響。在估算和選用時應充分考慮，使整個控制系統(tǒng)有較合理的性能價格比。
(二)輸入輸出模塊的選擇
輸入輸出模塊的選擇應考慮與應用要求的統(tǒng)一。例如對輸入模塊，應考慮信號電平、信號傳輸距離、信號隔離、信號供電方式等應用要求。對輸出模塊，應考慮選用的輸出模塊類型，通常繼電器輸出模塊具有價格低、使用電壓范圍廣、壽命短、響應時間較長等特點；可控硅輸出模塊適用于開關頻繁，電感性低功率因數(shù)負荷場合，但價格較貴，過載能力較差。輸出模塊還有直流輸出、交流輸出和模擬量輸出等，與應用要求應一致。
可根據(jù)應用要求，合理選用智能型輸入輸出模塊，以便提高控制水平和降低應用成本。
