一台主机最多可扩展3个通讯模块，即一个PLC 系统可同时带5个通讯口与不同的设备进行通讯（主机自带2个分别为RS232与RS485的通讯接口）。用通讯模块扩展的通讯口与主机自带的通讯口功能完全相同。 五、通讯模块端子配线图 S01RS/H01RS 配线图 H02RS 配线图 六、RS485和RS232接线图 RS485接线方式 RS232...

The DCP485 series is designed for full duplex operation over two-wire pairs. Outputs are tri-state, allowing multidropping of up to 32 units. Data rates are up to 115.2 K bits per second (baud). Four diagnostic LED indicators are provided for installation guidance and system troubleshooting....
the wire manufacturers publish plenty of data on wire versus data transmission rates versus distance. The point we are emphasizing on this page is the simple fact that most failures to communicate are due to lack of signal ground. Here is a functional diagram of what RS-485 should look like...
