BCNet-CP/CJ-S is used for Ethernet data acquisition of Omron CP1L/CP1E/CP1H/CJ1/CJ2/CS1/CG1/NX1P and other PLCs, which is very convenient to build a production management system. The module integrates WiFi function, supports AP mode, STA mode and AP+STA mode, which is very convenient to build a WiFi network, and perform PLC programming and data collection directly through WiFi.
BCNet-CP/CJ-S adopts plug-and-play design and does not occupy the PLC communication 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, supporting industrial control. Most SCADA software in the field supports OMRON Ethernet protocol and ModbusTCP master-slave communication. Support point table detection function.

BCNet-CP/CJ-S Function

  1. Installed on a 35mm guide rail, no external power supply required. The COM1 port is connected to the DB9T communication port of the PLC, and the COM2 expansion port is used for touch screen communication.
  2. Through the WEB server or the configuration diagnostic tool BCDevice, the device can be parameterized and run diagnostics.
  3. Automatic identification of PLC model, automatic matching of PLC and HMI serial parameters, without additional configuration.
  4. Integrated WiFi function, support AP mode, STA mode and AP+STA mode.
  5. PLC programming and data acquisition can be performed through WiFi.
  6. Realize Ethernet communication with Omron programming software CX-Programmer.
  7. Support FINS/UDP, FINS/TCP Ethernet protocol communication, support access to host computer software (MCGS, KepWare OPC server, etc.).
  8. Integrated ModbusTCP server, support FC1, FC2, FC3, FC5, FC6, FC16, Modbus data area is automatically mapped to PLC data area.
  9. Using FINS/UDP, FINS/TCP, ModbusTCP, all can realize high-level language (such as VB, VC, C#, etc.) programming, realize data communication with PLC, and facilitate the development of production management system.
  10. The SCADA (upper configuration software) that supports OPC channel communicates with PLC in OPC mode.
  11. It can realize CX-Progarmmer, FINS/TCP, FINS/UDP, ModbusTCP connection modes at the same time, and support the connection of 32 upper computers.
  12. Support firmware update on the user side through Ethernet, one purchase, permanent upgrade.
