 <description><![CDATA[6楼说得对，是在使用高速计数器。
LD M8000
OUT C238&nbsp; k8
是启动计数器开始计数的。（对X05计数）

除非用的是Q或A系列的PLC，那就不可得知是干什么用的了。]]></description>

 <description><![CDATA[以FX1S 为例
C238 对应 X3
C239 对应 X4
C240 对应 X5
其实C235-C255也不一定非要做高速用
具体情况要看楼主的机器上面的X1-X8间有没有接编码器一类的能发送高速脉冲的东西]]></description>

 <description><![CDATA[大家误会了,C235~C255不是记录M8000触点闭合与断开的次数.不存在(关电源后再开机)8次后
C238~C240条件满足输出.并且每一次开机后把以上计数器的数值输入D438至D440中去.

C235~C255是高速计数器.其输入端为X0~X5,而不是M8000,M8000触点闭合与断开不直接影响C235~C255的计数值. 
M8000触点闭合时,C235~C255开始计录X0~X5相 ..]]></description>

 <description><![CDATA[当PLC运行时,M8000常开触点闭合, C238、C239、C240开始计数工作，接着32位传送指令分别将C238的当前值给了D438和D439；将C239的当前值给了D440和D441；将C240的当前值给了D442和D443；]]></description>

 <description><![CDATA[32位停电保持型增/减计数器.M8000是RUN监视a触点,该程序的意思是当重新开机(关电源后再开机)8次后,C238~C240条件满足输出.并且每一次开机后把以上计数器的数值输入D438至D440中去,要看一下C238至C240的触点控制了什么就知道用意了]]></description>
