BCNet-SC is an Ethernet communication processor specially used for Schneider PLC,
It is suitable for data acquisition of Schneider Quantumn/Premium/TSX Micro/Twdio/M200/M218/M221/M241/M238/M251/M258/M340 series PLC.
BCNet-SC adopts a modular design and does not occupy the PLC programming port, that is, while the programming software/host computer software monitors the PLC data through Ethernet, the touch screen can communicate with the PLC through the multiplexing interface X2.

BCNet-SC Features:

  1. Realize the conversion between ModbusRTU serial protocol and ModbusTCP Ethernet protocol, non-transparent transmission;
  2. Support full-duplex asynchronous communication mode, high efficiency and fast speed;
  3. Compatible with half-duplex communication mode, wide application range;
  4. Support 6 PCs to communicate at the same time;
  5. Support all kinds of host computer software and touch screen, and access device data through ModbusTCP;
  6. The serial port supports RS232/485 interface mode, the communication port is multiplexed, and the baud rate can be selected from 9600bps to 115200bps;
  7. Support programming through high-level languages ​​(such as VB, VC, C#, etc.) to realize data communication with Schneider PLC;
  8. Special parameter configuration and testing tools;
  9. Support WEB page parameter configuration and firmware upgrade.
