每逢假期,老屋又會(huì)成為我和小伙伴們的樂園。在老屋的墻角打玻璃球,扎風(fēng)箏,捅老屋后檐下的蜂窩,爬上梧桐樹去摘梧桐花。小伙伴之間偶爾也會(huì)因?yàn)楝嵤掳l(fā)生矛盾,甚至?xí)ご蛟谝黄?,等大家勸開之后。沒占到便宜的那個(gè)就會(huì)瞪著眼睛,扭著頭憤憤而去。打定主意和老死不相往來??墒沁^不了幾天,他們又自然會(huì)和好如初。這就是老屋的童年。
老屋承載著兒時(shí)太多難以忘懷的回憶。院落中遮天蔽日的梧桐樹、收獲季節(jié)被磨得锃亮鋒利的鐮刀、滿滿一車收獲回來的小麥、還有的嚴(yán)厲、的慈愛、姐弟三人的爭執(zhí)……這些共同造就了老屋的獨(dú)特風(fēng)景,有歡樂、有悲傷、也有希望。
前年,由于統(tǒng)一搬遷,老屋被拆除了,雖然老屋沒了,然而,發(fā)生在老屋的悠悠往事卻如陳釀般甘甜而綿長,令人久久難忘……

永不過時(shí)的解決方案
PNOZmulti 2 是一款模塊化、功能眾多、應(yīng)用靈活的可配置控制,適用于多種應(yīng)用領(lǐng)域??梢栽谠O(shè)備或機(jī)器上實(shí)施多重安全功能,還可以根據(jù)用戶的需求進(jìn)行擴(kuò)展,它具有非常的性能特點(diǎn)!
● 經(jīng)認(rèn)證的硬件和確保可靠性;
● 友好的工具簡化了組態(tài)配置;
● 可配置輸入和輸出,縮短了項(xiàng)目周期;
● 針對(duì)每種要求提供模塊 - 擴(kuò)展靈活、簡單且經(jīng)濟(jì);
● 的診斷選項(xiàng)停機(jī)時(shí)間;
● 式端子簡化了接線,調(diào)試更快速。
PNOZ m EF 4AI:PNOZ multi2的新成員
PNOZ multi2作為可編程控制的“多面小能手”,其擴(kuò)展模塊和應(yīng)用領(lǐng)域也在不斷的豐富。皮爾磁于近期發(fā)布了PNOZ multi2的全新擴(kuò)展模塊:PNOZ m EF 4AI,適用于PLe/SIL3安全等級(jí)的安全模擬量擴(kuò)展模塊,適用于兩線制、三線制或四線制的類型。在基礎(chǔ)模塊PNOZ m B0的右側(cè)可以擴(kuò)展6塊,PNOZ m B1的右側(cè)可以擴(kuò)展12塊。
模擬量輸入可以連接電流的傳感器或編碼器,可以安全記錄任何測(cè)量變量,如壓力、溫度、灌裝液位、距離等。
PNOZ multi2適用于多種應(yīng)用領(lǐng)域,借助這款新模擬量輸入模塊,PNOZmulti 2在工業(yè)領(lǐng)域的將“如虎添翼”。

PNOZ m EF 4AI的技術(shù)特性
PNOZ m EF 4AI具有以下性能特點(diǎn):
● 符合EN ISO 13849-1 PL e以及EN IEC 62061 SIL CL 3要求;
● 快速、簡單的項(xiàng)目規(guī)劃:用于模擬輸入、比例和算術(shù)功能的功能塊;
● 4個(gè)的安全模擬電流輸入,每個(gè)輸入可單獨(dú)配置;
● 電流范圍:4-20 mA,測(cè)量范圍:0-25 mA,分辨率:15位 + 符號(hào)位;
● 使用靈活:可設(shè)置限值;
● 響應(yīng)時(shí)間短:模塊編程技術(shù)mIQ,在模塊中分散處理;
的配置
圖2,友好的配置
借助PNOZmulti Configurator 10.8.0中的模塊化程序mIQ,以及包括比例、加減、常數(shù)、平均數(shù)等豐富的功能塊,可以處理PNOZ m EF 4AI的相關(guān)配置。
在PNOZmulti Configurator工具中,可以使用用戶定義功能塊設(shè)置參數(shù):只需幾下鼠標(biāo),便可以對(duì)限值和監(jiān)控范圍進(jìn)行配置。另外,在配置期間,數(shù)字量中的模擬量測(cè)量值可用任何單位進(jìn)行縮放。結(jié)合PASvisu可視化,還可以顯示和評(píng)估模擬量值。
求平均值、差值計(jì)算等算術(shù)功能使PNOZ m EF 4AI更適合一些特殊應(yīng)用。
