BCNet-KYO is an economical Ethernet communication processor, which is designed to meet the increasing informatization needs of factory equipment (equipment network monitoring and production management). It is used in Koyo NK/SJ/SN/DL/D0/ SR/SM/SH
Ethernet data acquisition of other series PLCs is very convenient to build a production management system.
BCNet-KYO adopts a modular design and is equipped with a communication line when it leaves 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-KYO function

  1. Installed on a 35mm guide rail, the COM1 port is directly connected to the Koyo PLC programming communication port (RJ11), and a COM2 port is extended for touch screen communication. BCNet-KYO 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. Support Koyo K protocol, CCM2 HEX protocol and CCM2 ASCII protocol, automatically identify the protocol type and communication parameters of the PLC programming port without additional configuration.
  4. Realize the Ethernet communication function of Koyo PCL programming software DirectSOFT, realize program read/write (including RUN write function)/comparison, programmable controller operation monitoring and other functions through Ethernet.
  5. Support Koyo ECOM/UDP Ethernet protocol communication, support PC software (KepWare OPC server, etc.) to access with Koyo’s Ethernet driver.
  6. Integrated ModbusTCP server, support FC1, FC2, FC3, FC5, FC15, FC6, FC16, the Modbus data area is automatically mapped to the data area of ​​Koyo PLC.
  7. Using ModbusTCP mode or ECOM/UDP protocol, it can realize programming in advanced language (such as VB, VC, C#, etc.), realize data communication with Koyo PLC, and facilitate the development of production management system.
  8. The SCADA (upper configuration software) that supports OPC channel communicates with Koyo PLC in OPC mode.
  9. The programming software DirectSOFT connection, ModbusTCP and ECOM/UDP 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.
