Port-1通過PPI電纜連接到PC。
和連接的MMI電纜。 MMI是SIMATIC
而且，交換機(jī)保持在各種位置以檢查通信，
但是，關(guān)于MMI有一些問題。
即，PLC不通過端口0與MMI進(jìn)行通信，
特點：
i.e., The PLC is not communicating with the MMI through port-0,
The Port-1 is connected to PC via PPI cable.
but it is communicating through port-1, which is intended for PPI.
both RS 485 connector from the weight indicator
and the MMI cable the connected .
The MMI is SIMATIC TOUCHPANEL TP177A.The switch setting is RS 422/485.
