描述

許多人覺得PLC很神秘，其實PLC是很簡單的，其內(nèi)部的CPU除了速度快之外，其他功能還不如普通的單片機(jī)。通常PLC采用16位或32位的CPU，帶1或2個的串行通道與外界通訊，內(nèi)部有一個定時器即可，若要提高可靠性再加一個看家狗定時器足夠。

PLC的關(guān)鍵技術(shù)在于其內(nèi)部固化了一個能解釋梯形圖語言的程序及輔助通訊程序，梯形圖語言的解釋程序的效率決定了PLC的性能，通訊程序決定了PLC與外界交換信息的難易。對于簡單的應(yīng)用，通常以獨立控制器的方式運(yùn)作，不需與外界交換信息，只需內(nèi)部固化有能解釋梯形圖語言的程序即可。實際上，設(shè)計PLC的主要工作就是開發(fā)解釋梯形圖語言的程序。
