第二、掌握PLC的工作過(guò)程,我們需要知道PLC上電后是怎么工作的,比如說(shuō)PLC上電后,首先需要進(jìn)行內(nèi)部處理,內(nèi)部處理需要處理那些?PLC運(yùn)行后是怎么工作的,PLC的掃描過(guò)程是怎么樣的,對(duì)外部信號(hào)的采集,及對(duì)信號(hào)的刷新輸出的過(guò)程是怎么樣的?理解了PLC的掃描方式和工作原理及對(duì)信號(hào)的輸入采集輸出信號(hào)的刷新過(guò)程,對(duì)我們以后編寫(xiě)PLC程序的時(shí)候會(huì)有很大的幫助。
第三、掌握PLC中使用的一些軟元件,包括他的尋址。我們學(xué)習(xí)一個(gè)PLCzui起碼需要知道這個(gè)PLC里面所用的軟元件有那些,輸入、輸出信號(hào)用什么字母表示,輔助繼電器用什么符號(hào)表示,特殊輔助繼電器,寄存器等又是用什么來(lái)進(jìn)行表示,而且各自的分配是怎么分配的,是以十進(jìn)制數(shù)分配呢?還是字節(jié)分配?或是別的什么形式分配。存儲(chǔ)器所能存儲(chǔ)數(shù)據(jù)的大小又是如何。如果PLC加上數(shù)字量輸入/輸出擴(kuò)展模塊,模擬量輸入/輸出擴(kuò)展模塊后,這些擴(kuò)展的模塊的地址分配又是如何分配?等等,這些都是我們需要在這里面進(jìn)行掌握的
