智能化,從字面上可以理解為一種感官描述,直觀來說就是用‘物的智慧’來補(bǔ)充和代替‘人的智
慧’,讓人覺得‘物’具備了與‘人’一樣的智慧,這也讓很多企業(yè)提出‘只要用戶覺得智能就是智
能’的理念。”但邱伯華認(rèn)為,對工業(yè)產(chǎn)品來說,其性能指標(biāo)先進(jìn)性已經(jīng)不再是用戶關(guān)心的問題,
終端用戶更看重的是如何能夠更好地利用、和所的工業(yè)產(chǎn)品,關(guān)心對產(chǎn)品狀態(tài)的定量
化了解和未來趨勢的問題。
工業(yè)主要由設(shè)計者、制造與集成者以及使用者組成。與德國、美國相比,我國整體上仍較為薄弱
,但作為制造大國、使用大國,產(chǎn)品價值鏈?zhǔn)滞暾?,又有很?qiáng)的制造能力和豐富的使用,大量
數(shù)據(jù)在我國匯集,但數(shù)據(jù)并不會直接創(chuàng)造價值,真正能為企業(yè)帶來價值的是數(shù)據(jù)流,是數(shù)據(jù)經(jīng)過實(shí)時
分析后及時流向決策鏈的各個環(huán)節(jié),或是成為面向客戶創(chuàng)值服務(wù)的內(nèi)容和依據(jù),也就是“使用”
帶來的價值
入點(diǎn)數(shù)分,常用的有8點(diǎn)、12點(diǎn)、16點(diǎn)、32點(diǎn)等;按工作電壓分,常用的有直流5 V、12 V、24 V,交流110 V、220 V等選擇輸入模塊主要應(yīng)考慮以下兩點(diǎn):
(1) 根據(jù)現(xiàn)場輸入信號(如按鈕、行程開關(guān))與PLC輸入模塊距離的遠(yuǎn)近來選擇電壓的高低。一般,24 V以下屬低電平,其傳輸距離不宜太遠(yuǎn)。如12 V電壓模塊一般不超過10 m,距離較遠(yuǎn)的設(shè)備選用較高電壓模塊比較可靠。
(2) 高密度的輸入模塊,如32點(diǎn)輸入模塊,允許同時接通的點(diǎn)數(shù)取決于輸入電壓和環(huán)境溫度。一般,同時接通的點(diǎn)數(shù)不得超過總輸入點(diǎn)數(shù)的60%。
;按外部接線方式又可分為匯點(diǎn)輸入、分隔輸入等。
2.開關(guān)量輸出模塊的選擇
輸出模塊的任務(wù)是將PLC內(nèi)部低電平的控制信號轉(zhuǎn)換為外部所需電平的輸出信號,驅(qū)動外部負(fù)載。輸出模塊有三種輸出方式:繼電器輸出、雙向可控硅輸出和晶體管輸出。
1) 輸出方式的選擇
繼電器輸出價格便宜,使用電壓范圍廣,導(dǎo)通壓降小,承受瞬間過電壓和過電流的能力較強(qiáng),且有隔離作用。但繼電器有觸點(diǎn),壽命較短,且響應(yīng)速度較慢,適用于動作不頻繁的交直流負(fù)載。當(dāng)驅(qū)動電感性負(fù)載時,大開閉頻率不得超過1 Hz。
晶閘管輸出(交流)和晶體管輸出(直流)都屬于無觸點(diǎn)開關(guān)輸出,適用于通斷頻繁的感性負(fù)載。感性負(fù)載在斷開瞬間會產(chǎn)生較高的反壓,必須采取抑制措施
2) 輸出電流的選擇
模塊的輸出電流必須大于負(fù)載電流的額定值,如果負(fù)載電流較大,輸出模塊不能直接驅(qū)動,則應(yīng)增加中間放大環(huán)節(jié)。對于電容性負(fù)載、熱敏電阻負(fù)載,考慮到接通時有沖擊電流,故要留有足夠的裕量。
3) 允許同時接通的輸出點(diǎn)數(shù)
在選用輸出模塊時,還要看整個輸出模塊的滿負(fù)荷能力,如OMRON公司的CQM1-OC222是16點(diǎn)輸出模塊,每個點(diǎn)允許通過電流2 A(AC250 VDC24 V)。但整個模塊允許通過的大電流僅8 A。
分配輸入輸出點(diǎn)
一般輸入點(diǎn)與輸入信號、輸出點(diǎn)與輸出控制是一一對應(yīng)的;在個別情況下,也有兩個信號用一個輸入點(diǎn)的,那樣就應(yīng)在接入輸入點(diǎn)前,按邏輯關(guān)系接好線(如兩個觸點(diǎn)先串聯(lián)或并聯(lián)),然后再接到輸入點(diǎn)。
1. 明確IO通道范圍
不同型號的PLC,其輸入輸出通道的范圍是不一樣的,應(yīng)根據(jù)所選PLC型號,弄清相應(yīng)的IO點(diǎn)地址的分配。
