描述

使用CPU內(nèi)置的高速計(jì)數(shù)器和高速脈沖發(fā)生器處理序列脈沖信號(hào)

使用部分CPU數(shù)字量輸入點(diǎn)的硬件中斷功能，在中斷服務(wù)程序中處理；進(jìn)入中斷的延時(shí)可以忽略S7-200擁有“直接讀輸入”和“直接寫輸出”指令，可以越過(guò)程序掃描周期的時(shí)間限制，使用部分CPU數(shù)字量輸入點(diǎn)的“脈沖捕捉”功能捕捉短暫的脈沖。

注意：S7-200系統(tǒng)中最小周期的定時(shí)任務(wù)為1ms。所有實(shí)現(xiàn)快速信號(hào)處理的措施，都要考慮所有限制因素的影響。例如，為一個(gè)需要毫秒級(jí)響應(yīng)速度的信號(hào)選擇500μs輸出延時(shí)的硬件，顯然是不合理的。
