如果是在做实验，短距离话3连3、8连8，自己焊也没什么问题，*初开始学S7-200PLC时，我也都是用的D型接头自己焊的，（有时没D型接头时，被逼无奈时用线直接插到通信口孔里）。记得在断电情况下连接，连接好就上电。现在条件允许了，就按规范来作，用PROFIBUS总线连接器和电缆，连接二个或多个S7-200PLC，这样是完全可以的，在实际现场也是这样使用的。
这样只能用于连接二个或多个S7-200PLC，也就是说这样可以用于200PLC之间的通信，比如常用的PPI通信。如果S7-200与与300、400或者HMI通讯，就不能这样使用了，你可以使用PROFIBUS通讯或以太网通信，比如S7-200CPU通过EM277模块连接到PROFIBUS-DP网络，或通过CP243-1以太网模块与其它S7-200、S7-300或S7-400控制器进行通信。
