BCNet-VB is an economical Ethernet communication processor, which is designed to meet the increasing demands of factory equipment informatization (equipment network monitoring and production management). It is used for Ethernet data of Fengwei VB/VH series PLC. Collection, it is very convenient to build a production management system.
BCNet-VB 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-VB function

  1. Installed on a 35mm guide rail, the COM1 port is directly connected to the VB programming communication port (USB port), and a COM2 port is extended for touch screen communication.
  2. Integrate the WEB server, through which the device parameters can be set and the operation diagnosis can be made.
  3. Self-adaptive to the communication parameters of Fengwei PLC programming port, no additional settings are required.
  4. Realize the Ethernet communication function of Fengwei PLC programming software Ladder Master.
  5. Support Mitsubishi MC (1E frame) protocol communication, which can connect Fengwei PLC to Mitsubishi monitoring system conveniently and quickly.
  6. Integrated ModbusTCP server, support FC1, FC2, FC3, FC5, FC6, FC16, Modbus data area is automatically mapped to the data area of ​​Fengwei PLC.
  7. Using MC communication protocol or ModbusTCP, programming in advanced languages ​​(such as VB, VC, C#, etc.) can be realized, and data communication with Fengwei PLC can be realized, which is convenient for the development of production management system.
  8. The SCADA (upper configuration software) supporting OPC channel communicates with Fengwei PLC in OPC mode.
  9. Allow 6 PCs to collect PLC data at the same time, and the connection protocol can be used arbitrarily.
  10. Support firmware upgrade on the user side through Ethernet.
