问：两个相同型号的西门子S7-300PLC 

第一台 STOP 黄灯常亮    可以下载硬件和程序

第二台STOP 黄灯一直闪烁   下载的时候就找不到该PLC

请问原因

答：、第一台 STOP 黄灯常亮    可以下载硬件和程序？

下载正确的硬件组态与程序后，将方式选择开关拨至到RUN位置，即可。

、第二台STOP 黄灯一直闪烁   下载的时候就找不到该PLC？

如果CPU 的STOP 灯出现慢闪，这是CPU在请求被动格式化，只有此时可以用MRES按钮格式化MMC卡，把卡中的错误信息清除，具体操作方法如下：

将模式开关打到MRES并保持直到STOP 灯保持常亮（约九秒），并在其后两秒内迅速开关，使其返回到STOP 再迅速按回到MRES位置，此时，STOP 灯快速闪烁，表示正在格式化。保持开关在MRES位置，直到STOP 灯常亮，格式化完成。

注意：要使用规定的操作顺序。否则，MMC就不能进行格式化，而是返回存储器复位状态。这种情况是在CPU的STOP 灯慢速闪烁时使用，是一种被动的格式化，在正常使用的情况下无法用MRES格式化MMC卡。

问：一般我们编写程序后，这个源文件都是空的，但有的人却把程序块或数据块都生成源文件，这样有什么目的？

答：您好，这是不同的编程方式。可以用在源文件编写各种S7程序块，通过编译生成各块；也可以在"Block"下单独编辑块。

标准版的STEP7只有S7-STL源文件，通过添加不同的语言选件，可以支持S7-SCL, S7-SFC, S7-CFC, S7-GRAPH等其他源文件编辑编译。

问：我在MICROWIN里在为224做系统配置时，里面有数据断电保存功能，但我在大家讨论区里看到S7-200里只有RAM，不能进行数据断电保存。

答：应用S7-200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内可以保存 

用户编程使用相应的特殊寄存器功能，将数据写入EEPROM保存 

 上述前三个数据保持功能都是在“系统块－数据保持”中设置。

S7-200和S7-1200有字节、字和双字的循环移位指令。S7-300/400只有双字循环移位指令。在它的基础上，可以实现任意位的循环移位，下面以8位循环移位为例。本例来源于作者的《跟我动手学S7-300/400PLC》。

    MB0是双字MD0的高字节，MD0每次循环左移1位后，高位M0.7的数据被移到MD0低位的M3.0（见下图）。为了实现MB0的循环移位，移位后如果M3.0为1状态，将MB0的低位M0.0置位为1，反之将M0.0复位为0，相当于MB0的高位M0.7移到了MB0的低位M0.0。

    MD0每次循环右移1位之后，MB0的低位M0.0的数据被移到MB1高位的M1.7。移位后根据M1.7的状态，将MB0的高位M0.7置位或复位，相当于MB0的低位M0.0移到了MB0的高位M0.7。

    在程序段3，用MOVE指令将MB0的值传送到QB4，可用QB4来控制8位彩灯。

    根据本例的思路，不难实现任意位的循环移位。

问：已把pg/pc interface设置为PC internal(local)

但下载硬件时提示连接不能建立

答：1、将 PC Station 的名称改为计算机名。

2、将组态信息传递至 Station Configuration Editor，点击 PC Station 右键 -> PLC -> Config，点击组态按钮(如果是灰色的先取消激活“使用所组态的计算机名称”)。

3、选中 PC Station，点击下载。
