BCNet-Q

BCNet-Q is an economical Ethernet communication processor, which is designed to meet the increasing informatization requirements of factory equipment (equipment network monitoring and production management). It is used for Ethernet data acquisition of Mitsubishi Q series PLC round ports. , which is very convenient for building a production management system.
BCNet-Q adopts a modular design with communication lines. 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-Q supports the vast majority of SCADA software in the field of industrial control and supports two communication methods: Mitsubishi MC Ethernet protocol and Modbus TCP.

BCNet-Q Features

  1. Installed on a 35mm guide rail, no external power supply is required. The COM1 port is connected to the MD6 programming communication port of Q, and the COM2 expansion port is used for touchscreen communication.
  2. Through the WEB server or the configuration diagnostic tool BCDevice, the device can be parameterized and run diagnostics.
  3. The baud rate of the Q programming communication port is automatically adjusted, which can meet the needs of large data communication.
  4. Support Ethernet communication of MELSOFT products (GX Works2, GX Developer, etc.).
  5. Support host computer MC Ethernet protocol (MELSEC Communication Protocol) communication, support host software (MCGS, IFIX, INTOUCH, KepWare OPC server, etc.) access.
  6. Integrated ModbusTCP server, support FC1, FC2, FC3, FC5, FC6, FC16, Modbus data area is automatically mapped to Q data area.
  7. Support BCNetTCP/IP transparent transmission protocol communication.
  8. Using MC communication protocol or transparent transmission, programming in advanced languages ​​(such as VB, VC, C#, etc.) can be realized, data communication with Mitsubishi Q can be realized, and a production management system can be developed conveniently.
  9. The SCADA (upper configuration software) supporting the OPC channel communicates with Q in OPC mode.
  10. It can realize MELSOFT connection, MC protocol connection, BCNetTCP transparent transmission, and Modbus TCP connection at the same time. Support the connection of 6 host computers.
  11. Support firmware updates on the user side through Ethernet, one purchase, and permanent upgrade.
