问：在S-200下载中，出现找不到指定的模块？因为什么，谢谢！
答：通讯连上了，可能是软件没有装好，建议重装下S7-200软件，最好重装操作系统。
检查电脑操作系统与版本兼容性问题。
问：EM235 CN用到温度控制，温度变送器该用什么型号的。
答：235能测的那可就多了：
单极性：0-50mV 0-100mV 0-500mV 0-1V 0-5V 0-20mA 0-10V
双极性：正负25mV 正负50mV 正负100mV 正负250mV
正负500mV 正负1V 正负2.5V 正负5V 正负10V
推荐选用0-20毫安的，另外把你下次要问的问题先给答案给你：
有关235的拨码开关设定参见下列手册第432页，附录A的模拟量扩展模块
问：输入I0.0 I0.1 I0.2
输出Q0.0 Q0.1 Q0.2
要求实现功能：
1.当I0.0 I0.1 I0.2均为0时 Q0.0 Q0.1 Q0.2也为0
2.当i0.0 i0.1 i0.2中仅有一个为1时 那么对应的Q也为1 例如（I0.0=0 I0.1=1 I0.2=0 那么Q0.0=0 Q0.1=1 Q0.2=0）
3.当i0.0 i0.1 i0.2中有不止一个为1时，那么对应的Q 要求轮流为1，切换时间为20秒。
例如（I0.0=1 I0.1=0 I0.2=1 那么Q0.0=1 Q0.1=0 Q0.2=0，20秒后Q0.0=0 Q0.1=0 Q0.2=1，20秒后Q0.0=1 Q0.1=0 Q0.2=0...）如此循环.
如果I0.0 I0.1 I0.2都为1 那么Q0.0 Q0.1 Q0.2也是轮流通 20秒切换

问：如题，我是搞维护工作的，想知道怎么确认我的离线程序是否与PLC在线程序完全相同。有没有方便快捷的方法？我比较熟悉的施耐德系列的PLC，在CONCEPT和UNITY编程软件中，在线连接PLC后都会自动检查编程器的程序和PLC在线程序是否相等，我想知道step7中有没类似功能，我这里PLC很多，好多程序的功能块也很多，一个一个打开检查太耽误时间了。我想找个简单快捷完整检查整个项目的方法。
答：用step7打开离线程序，然后用鼠标选中其中一个程序的blocks，选择option菜单下的compare blocks，在弹出的对话框中可以选择online/offline（CPU在线程序和当前程序的比较）和Path1/Path2（硬盘中的两个程序比较），你可以选择前一项，点击compare按钮，系统就会列出两个程序的不同。
问：项目大致配置：单套系统为S7-200PLC 挂一个模拟量输入，一个输出。总共12套，结构完全一样，现在需要12套通过总线 把信号通过以太网传给中控室。
我的方案:用个S7-315+CP343 通过315 走MPI 协议把12套子系统需要给中控的数据采集下，然后通过CP343 传给中控需要的数据。
问题：1.业主未提供方案，是否有更合理的方案，？麻烦简单描述
2.走MPI 协议，（不用EM277）315能否挂下12套200 的PLC？
3.若采用315 挂ET200 做，再加CP343，此方案是否更具优势？
答：1、业主未提供方案，是否有更合理的方案？
方案是可以，但MPI的实用通信波特率一般为187.5Kbit/s，通讯速率相对较低，且通讯距离不可超越15米/段，否则需采用RS485的中继器(Siemens的RS485中继器价格太高)。
2、走MPI 协议，（不用EM277）315能否挂下12套200 的PLC？
可以的，建议采用S7-200的V区通讯数据对应S7-300的DB块，且每个S7-200对应一个S7-300的DB块。
3、若采用315 挂ET200 做，再加CP343，此方案是否更具优势？
a、采用上述方案，这个方案你的项目组态很可能会轻松点，但CPU-315一旦掉电，整个系统均失去控制。
b、而CPU-315-2DP带EM277（S7-200）的方案与采用MPI与S7-200通讯的方案相比，没有优势，可靠性方面可能会差一些，不建议采用此方案。
c、我建议：S7-300的cpu选用CPU312或CPU313即可，没必要选用有DP口的CPU315！而且S7-300的工作仅仅是为了实现12套S7-200与上位机快速通讯而配置的接口转换机！！！，CPU没没有具体的工程运算。 咨询热线：18150695049
