1785-CHBM模塊② 數(shù)字量輸出模塊采用輸出回路密碼鎖設(shè)計(jì)，通過模塊的反讀、校核及執(zhí)行的聯(lián)合控制保證在任何情況下不會(huì)發(fā)生誤動(dòng)。由于模塊本身具有CPU可以實(shí)現(xiàn)精確的脈沖型輸出脈寬的控制，和其它通用PLC不同，NA- PLC的脈沖寬度控制是由模塊來控制的，CPU模塊將動(dòng)作信息和動(dòng)作時(shí)間發(fā)送到輸出模塊，輸出模塊完成輸出動(dòng)作及動(dòng)作時(shí)間的控制；③ 模擬量采集采用了飛度電容的設(shè)計(jì)方法，保證了內(nèi)部電路和外界干擾的絕對(duì)隔離，大大提高了采集精度，最大限度地降低了模擬量漂移；④ 溫度量模塊設(shè)計(jì)突破了常規(guī)溫度量模塊所有通道共用一路恒流源的設(shè)計(jì)，采用了先進(jìn)的每路獨(dú)立恒流源設(shè)計(jì)，因此有效地避免了因一路信號(hào)干擾過大而使其它各路產(chǎn)生串?dāng)_的問題，從而大大提高了采集速度和抗干擾性。系統(tǒng)功能設(shè)計(jì)① 上位機(jī)利用組態(tài)軟件編制相應(yīng)的程序，實(shí)現(xiàn)對(duì)工藝流程圖和測(cè)量數(shù)據(jù)的顯示，通過上位機(jī)由人工選定其操作的方式即自動(dòng)手動(dòng)、自動(dòng)集控、手動(dòng)操作。② 自動(dòng)手動(dòng)就是利用鼠標(biāo)起動(dòng)\停止單個(gè)的可控設(shè)備； ③ 手動(dòng)操場利用現(xiàn)場操作臺(tái)上的按鈕起動(dòng)\停止單個(gè)的可控設(shè)備；④ 自動(dòng)集控就是整個(gè)控制系統(tǒng)從起動(dòng)、運(yùn)行、停止及運(yùn)行過程中的故障報(bào)警、保護(hù)停機(jī)等整個(gè)過程的自動(dòng)運(yùn)行及在線監(jiān)視。3.1 NA400PLC軟件設(shè)計(jì) 程序控制系統(tǒng)的軟件設(shè)計(jì)采用梯形圖，并采取了模塊化的設(shè)計(jì)方式，把整個(gè)控制系統(tǒng)所需要完成的功能分成若干模塊，然后分別進(jìn)行設(shè)計(jì)，這樣做的優(yōu)點(diǎn)是設(shè)計(jì)方便，便于修改程序，使得程序條理清晰。① 自動(dòng)集控功能模塊設(shè)計(jì)② 自動(dòng)手動(dòng)功能模塊設(shè)計(jì)③ 模擬量處理模塊設(shè)計(jì)④ 與組態(tài)王通訊模塊設(shè)計(jì)⑤ 報(bào)警模塊設(shè)計(jì)3.2 組態(tài)王軟件設(shè)計(jì) 組態(tài)王軟件包由TOUCHEXPLORER、TOUCHVIEW、DDE服務(wù)程序等主要部分組成，分別負(fù)責(zé)系統(tǒng)工程的建立、操作畫面的制作，操作畫面的運(yùn)行，以及系統(tǒng)中NAPLC和組態(tài)王之間的數(shù)據(jù)通訊。
principle
1: Open the positive and negative pressure laminating machine, and then put in the door plate with film.
2: After pressing the automatic button, the upper cover of the machine is closed, and then the safety pin is locked. In this closed space, it starts to heat, start to inhale under positive pressure, and start to deflate under negative pressure.
3: At this time, the silica gel mold began to squeeze the door panel to achieve the effect of coating.
4: After baking for a period of time, the positive pressure and negative pressure begin to deflate. After a period of time or when the air pressure is the same as the external air pressure, the safety is opened and the upper cover of the machine is opened.
3、 Program introduction
1. Operation screen: This screen mainly displays PLC IO status and start / stop of automatic screen. Automatic start, click start, the box starts to close, and then the safety cylinder is closed. After a period of time, the suction of positive pressure and negative pressure starts. After a period of time, the suction of positive pressure and negative pressure stops, and the positive
