科學(xué)的PLC編程步驟其實很簡單,但往往大多數(shù)工程師就是認(rèn)為簡單而忽略很多細(xì)節(jié)。細(xì)節(jié)的忽略,必然會在以后出現(xiàn)問題。想避免日后的問題,只有好好的遵守規(guī)則,沒有規(guī)矩不成方圓,plc編程一樣有其自身的規(guī)矩。
*步:閱讀產(chǎn)品說明書
*步看起來再簡單不過了,但很多工程師都做不到。認(rèn)為這一步是浪費(fèi)時間,甚至只從供貨方培訓(xùn)來了解設(shè)備。
仔細(xì)閱讀說明書是編程的*步,首先要閱讀安全守則,知道哪些執(zhí)行機(jī)構(gòu)可能會對人身造成傷害,哪些機(jī)構(gòu)間容易發(fā)生撞擊,當(dāng)發(fā)生危險時如何解決,這些致命的問題都在安全守則中,為什么不去看呢?
此外,關(guān)于設(shè)備每個元件的特性,使用方法,調(diào)試方法也在說明書中,不去閱讀,即使程序正確,如果元件沒有調(diào)試好,設(shè)備一樣不能工作。再有,所有的電路圖、氣動液壓回路圖、裝配圖也在說明書中,不去閱讀它怎么知道沒種元件可以做何種改造呢。
