1771-VHSCK控制器
S7200与S7300之间采用MPI通讯方式时， S7200 PLC中不需要编写任何与通讯有关的程序，只需要将要交换的数据整理到一个连续的V 存储区当中即可，而S7300中需要在OB1（或是定时中断组织块OB35）当中调用系统功能X_GET（SFC67）和X_PUT(SFC68)，实现S7300 与S7200之间的通讯，调用SFC67和SFC68时VAR_ADDR参数填写S7200的数据地址区，这里需填写P#DB1.××× BYTE n 对应的就是S7200 V存储区当中VB××到VB（××＋n）的数据区。
首先根据S7300的硬件配置，在STEP7当中组态S7300站并且下载，注意S7200和S7300出厂默认的MPI地址都是2，所以必须先修改其中一个PLC的站地址，例子程序当中将S7300 MPI地址设定为2，S7200地址设定3，另外要分别将S7300和S7200的通讯速率设定一致，可设为9.6K，19.2K，187.5K三种波特率.
分别在STEP7 MicroWin32 和STEP7当中监视S7200和S7300 PLC当中的数据，
通过CP5611，STEP7 MicroWin32， Set PG/PC Interface可以读取S7200和S7300的站地址，
站地址0代表的时进行编程的PG，即当前连接PLC的PC。
