a问：要求在西门子S7-200PLC的EM231的某个通道上的输入（或者变换后的值）在PLC断电后能保存下来，例如，一周的时间。下次上电后能再次被使用，能办到吗？

答：应用西门子S7-200PLC时，可以选用以下几种数据保持方法：

.CPU的内置超级电容，断电时间不太长时，可以为数据和时钟的保持提供电源缓冲 .

.CPU上可以附加电池卡，与内置电容配合，长期为时钟和数据保持提供电源 .

.设置系统块，在CPU断电时自动保存M区中的14个字节数据 .

.在数据块中定义不需要更改的数据，下载到CPU内可以永久保存 

用户编程使用相应的特殊寄存器功能，将数据写入EEPROM永久保

问：两台电脑同时监控同一个PLC时，其中一个用的是PPI通信，而另一台电脑用的是EM277 DP通信，请问我这个STEP7 MicroWin内PG/PC接口如何设置？不可能同时把两个都一起设置啊？

答：请问我这个STEP7 MicroWin内PG/PC接口如何设置

由于是两台计算机进行监控，因此用PPI通信的计算机您可以设成PPI方式，而使用DP通信的您可以设置成DP通信，只要两台计算机分别设置就可以了，不需要两个在一起设置。

问：CALL   Scale_I_to_R这个在哪调用？什么意思？

答：这个是个子程序， 看字面上应该是把 I 转化成R 的子程序  如果没猜错的话 是模拟量 标准化程序    

在哪里调用  打开你的STEP7  win    然后看看左边程序块----找到 SCALE_I_TO_R     这个就是你调用的子程序  双击进入  

注意  这个子程序是自己写的  不是哪里有库能调用的 相当于FC。

问：有三个站其中一个S7400，两个S7300，以前在运行过程中没有任何问题，前几天S7300站的CP343-1模块BF灯同时点亮，现在一直红色常亮，但是设备都正常运行，请问怎么处理啊？

答：这个是你的有一个模块中有一个信号有问题或者有干扰造成但不影响设备正常运行，这个不需要处理，如果非要处理的话等停机了再处理吧。

：调试时想强制PQW输出，在强制变量表里输入提示地址无效，输入MW,DB都一样。想问下，强制变量表里能强制哪些数据，程序里有覆盖的话，是否强制后下一次的扫描里又被覆盖。

答：首先并不是所有西门子S7-300PLC都支持强制功能（Force），检查PLC面板上是否有“Force”（强制）指示灯；其次，强制功能一般用于I/0保持指定的值，与修改变量不同，一旦你强制了I/O的值，这些I/O将不受程序的影响，始终保持你设定的值，直至你取消了强制。所以在强制变量表里强制设定的数据，程序里有覆盖的话，是不会强制后在下一次的扫描里又被覆盖，一种保持该值，即使你关闭强制窗口，也不能取消强制功能，必须通过单击右键，在快捷菜单中单击“Stop Forcing”（停止强制）选项来取消强制。

一般你不能直接强制PQW（它属于外部输出寄存器），不经过过程映像输出直接访问本地的和分布式的输出模块，所以在强制变量表里输入提示地址无效；而MW是位于PLC中系统存储区、DB位于工作存储区，它们是PCL内部的存储区，在执行程序过程中，位存储区用来保存控制逻辑的中间操作状态或其他控制信息，而数据块DB可以被其他程序调用修改其内部数据，所以在程序执行过程中是会被覆盖的，所以也不能执行强制。

问：由于生产需要，我想请教下，能否做到S7-200与带485之类的指纹识别器通讯连接，做到触摸屏设置和修改某些机密参数时要通过上指纹识别来确认权限身份？

举个简单的例子，比如通过指纹识别接通或者断开某个常开点，达到允许对某个参数的修改。

不知道我的表达让大家明白我的意思，望大家给我点意见或者启发，再此感谢！

答：完全可以的。。

你只需要选择能通讯的方式 比如说支持MODBUS Rtu 协议的这个指纹识别器，  你只需要要通讯的数据区做处理。。 

但是建议没这个必要  你可以在触摸屏设置密码   才能修改程序啊   你这样投资大了
