ACC-24E2A模擬量輸出模塊PLC輸入輸出(I/O)點數(shù)的估算
I/O點數(shù)估算時應考慮適當?shù)挠嗔?,通常根?jù)統(tǒng)計的輸入輸出點數(shù),再增加10%~20%的可擴展余量后,作為輸入輸出點數(shù)估算數(shù)據(jù)。實際訂貨時,還需根據(jù)制造廠商可編程邏輯控制器的產(chǎn)品特點,對輸入輸出點數(shù)進行圓整。
二、存儲器容量的估算
存儲器容量是可編程序控制器本身能提供的硬件存儲單元大小,程序容量是存儲器中用戶應用項目使用的存儲單元的大小,因此程序容量小于存儲器容量。設計階段,由于用戶應用程序還未編制,因此,程序容量在設計階段是未知的,需在程序調試之后才知道。為了設計選型時能對程序容量有一定估算,通常采用存儲器容量的估算來替代。
存儲器內(nèi)存容量的估算沒有固定的公式,許多文獻資料中給出了不同公式,大體上都是按數(shù)字量I/O點數(shù)的10~15倍,加上模擬I/O點數(shù)的100倍,以此數(shù)為內(nèi)存的總字數(shù)(16位為一個字),另外再按此數(shù)的25%考慮余量。在制造工業(yè)中存在大量的開關量為主的開環(huán)的順序控制,它按照邏輯條件進行順序動作號按照時序動作;另外還有與順序、時序無關的按照邏輯關系進行連鎖保護動作的控制;以及大量的開關量、脈沖量、計時、計數(shù)器、模擬量的越限報警等狀態(tài)量為主的—離散量的數(shù)據(jù)采集監(jiān)視。由于這些控制和監(jiān)視的要求,使PLC發(fā)展成了取代繼電器線路和進行順序控制為主的產(chǎn)品。PLC廠家在原來CPU模板上提逐漸增加了各種通訊接口,現(xiàn)場總線技術及以太網(wǎng)技術也同步發(fā)展,使PLC的應用范圍越來越廣泛。 PLC具有穩(wěn)定可靠、價格便宜、功能齊全、應用靈活方便、操作維護方便的優(yōu)點,這是它能持久的占有市場的根本原因。
