日期：2018-10-9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
