【服務(wù)標(biāo)準(zhǔn)】降低客戶(hù)的停機(jī)時(shí)間以及維護(hù)成本,減少所有的工業(yè)機(jī)械和生產(chǎn)設(shè)備運(yùn)行故障,延長(zhǎng)控制系統(tǒng)的壽命!
(4) 當(dāng)排料閥打開(kāi)時(shí)，進(jìn)料泵的啟動(dòng)必須被鎖定。
(5) 在啟動(dòng)進(jìn)料泵后1 s內(nèi)必須打開(kāi)入口閥和進(jìn)料閥。
(6) 在進(jìn)料泵停止后(來(lái)自流量傳感器的信號(hào))閥門(mén)必須立即被關(guān)閉以防止配料從泵中泄露。
(7) 進(jìn)料泵的啟動(dòng)與一個(gè)時(shí)間監(jiān)控功能相結(jié)合，換句話(huà)說(shuō)，在泵啟動(dòng)后的7 s之內(nèi)，流量傳感器會(huì)報(bào)告溢出。
(8) 當(dāng)進(jìn)料泵運(yùn)行時(shí)，如果流量傳感器沒(méi)有流量信號(hào)，進(jìn)料泵必須盡可能快地?cái)嚅_(kāi)。
(9) 必須對(duì)進(jìn)料泵啟動(dòng)的次數(shù)進(jìn)行計(jì)數(shù)(維護(hù)間隔)。
2) 混合罐區(qū)域
(1) 當(dāng)罐的液面?zhèn)鞲衅髦甘尽耙好娴陀诘拖蕖被蚺帕祥y打開(kāi)時(shí)，攪拌電機(jī)的啟動(dòng)必須被鎖定。
(2) 攪拌電機(jī)在達(dá)到額定速度時(shí)要發(fā)出一個(gè)響應(yīng)信號(hào)。如果在電機(jī)啟動(dòng)后10 s內(nèi)還未接收到該信號(hào)，則電機(jī)必須被斷開(kāi)。
(3) 必須對(duì)攪拌電機(jī)的啟動(dòng)次數(shù)進(jìn)行計(jì)數(shù)(維護(hù)間隔)。
(4) 在混合罐中必須安裝三個(gè)傳感器。① 罐裝滿(mǎn)：一個(gè)常閉觸點(diǎn)。當(dāng)達(dá)到罐的高液面時(shí)，該觸點(diǎn)斷開(kāi)。② 罐中液面高于低限：一個(gè)常開(kāi)觸點(diǎn)。如果達(dá)到低限，該觸點(diǎn)關(guān)閉。③ 罐非空：一個(gè)常開(kāi)觸點(diǎn)，如果罐不空，該觸點(diǎn)閉合。
3) 排料區(qū)域
(1) 罐內(nèi)產(chǎn)品的排出由一個(gè)螺線(xiàn)管閥門(mén)控制。
(2) 這個(gè)螺線(xiàn)管閥門(mén)由操作員控制，但是遲在“罐空”信號(hào)產(chǎn)生時(shí)，該閥必須被關(guān)閉。
(3) 當(dāng)攪拌電機(jī)在工作或罐空時(shí)打開(kāi)排料閥必須被鎖定。
3. 定義邏輯塊
通過(guò)程序塊可以將用戶(hù)程序分布到不同的塊中并建立塊調(diào)用的分層結(jié)構(gòu)來(lái)組織程序。本例中用戶(hù)程序主要由組織塊OB1、功能塊FB1、功能FC1及三個(gè)數(shù)據(jù)塊DB1～DB3組成。圖5.12所示為結(jié)構(gòu)化編程的塊的分層調(diào)用結(jié)構(gòu)。
(1) OB1：與CPU操作系統(tǒng)的接口，包含主要程序。在OBl中調(diào)用塊FBl和FCl并傳送控制過(guò)程所需的特定參數(shù)。
(2) FB1：用于配料A的進(jìn)料泵、配料B的進(jìn)料泵和攪拌電機(jī)的控制。由于要求一致(接通、斷開(kāi)、計(jì)數(shù)應(yīng)用程序等)，可以通過(guò)同一個(gè)功能塊實(shí)現(xiàn)。
(3) 背景DB1～DB3：用于控制配料A、配料B的進(jìn)料泵和攪拌電機(jī)的實(shí)參及靜態(tài)數(shù)據(jù)各不相同，因此分別存儲(chǔ)在與FBl相關(guān)的三個(gè)背景DB中。
(4) FC1：用于閥的控制。配料A和B的入口閥和進(jìn)料閥以及排料閥共同使用本邏輯塊。
指定符號(hào)名
如果在用戶(hù)程序中使用了符號(hào)，則必須用STEP 7在符號(hào)表中對(duì)這些符號(hào)進(jìn)行定義。表5.6所示為所用的程序組件的符號(hào)名及地址。
