BCNet-FB is an economical Ethernet communication processor. It is designed to meet the increasing demand for informationization of factory equipment (equipment network monitoring and production management). It is used in FATEK FBs/FBe series and Fuji WSZ series PLC. It is very convenient to build a production management system.
BCNet-FB adopts a modular design and comes with a communication line from the factory. It does not occupy the PLC programming port, that is, while the programming software/host computer software monitors the PLC data through the Ethernet, the touch screen can communicate with the PLC through the multiplexing interface X2.

BCNet-FB Features:

  1. Installed on a 35mm guide rail, the COM1 port is directly connected to the PLC programming communication port, and a COM2 port is extended for touch screen communication. BCNet-FB can directly obtain power from the PLC programming communication port, or external 24VDC power supply.
  2. Integrate a WEB server, through the web page, you can set device parameters and run diagnostics, and set a login protection password to prevent tampering with configuration data.
  3. Self-adaptive to the communication parameters of FATEK PLC programming port, no additional settings are required.
  4. Realize the Ethernet communication function of WinProladder, the PLC programming software of FATEK, and realize the functions of reading/writing (including writing in RUN)/comparing, and monitoring the operation of programmable controller through Ethernet.
  5. Integrated ModbusTCP server, support FC1, FC2, FC3, FC5, FC6, FC16, Modbus data area is automatically mapped to the data area of ​​FATEK PLC.
  6. The BCNetTCP transparent transmission method can be adopted, and the upper software (programming software WinProladder, MCGS, IFIX, INTOUCH, KepWare OPC server, etc.) can be used for convenient and quick access.
  7. Using ModbusTCP, it can realize high-level language (such as VB, VC, C#, etc.) programming, realize data communication with FATEK PLC, and facilitate the development of production management system.
  8. SCADA (upper configuration software) that supports OPC channel communicates with FATEK PLC in OPC mode.
  9. The programming software WinProladder connection, ModbusTCP, BCNetTCP transparent transmission connection can be realized, allowing 6 PCs to collect PLC data at the same time, and the connection protocol can be used arbitrarily.
  10. Support firmware update on the user side through Ethernet, provide firmware with more functions for free, purchase hardware once, and upgrade permanently.
