BCNet-S7300 is used for Ethernet data acquisition of PLCs such as Siemens S7-200/SMART S7-200/S7-300/S7-400/Siemens CNC 840D, 840DSL, etc. It is very convenient to build a production management system.
BCNet-S7300 does not occupy the PLC programming port, that is, while the programming software/host computer software monitors and collects PLC data through Ethernet, the touch screen can communicate with the PLC through the extended RS485 port.
BCNet-S7300 supports the vast majority of SCADA software in the field of industrial control and supports Siemens S7TCP Ethernet protocol and Modbus TCP protocol.

BCNet-S7300 Features:

  1. Support multi-master communication, the expansion port can be connected to a touch screen or other masters.
  2. Through the WEB server or the configuration diagnostic tool BCDevice, the device can be parameterized and run diagnostics.
  3. The baud rate is 9.6Kbps~6Mbps adaptive.
  4. It can be directly installed on the PPI/MPI/PROFIBUS communication port of the PLC, without an external power supply.
  5. Support Siemens S7 Ethernet communication driver, including MicroWIN, STEP7, Portal, WinCC, etc.
  6. Users can use high-level language programming (such as VB, VC, C#, etc.) according to the BCNetS7 protocol to realize data communication with S7-200/300/400, which is convenient for developing production management systems.
  7. The BCNetS7 OPC server is provided free of charge, and the SCADA that supports the OPC channel communicates with the PLC in the OPC way.
  8. Integrated ModbusTCP server, Modbus data area can be automatically or edited to map to S7-200/300/400 registers.
  9. It can realize S7TCP connection and Modbus TCP communication at the same time and supports up to 32 connections of the upper computer.
  10. Support firmware updates on the user side through Ethernet, one purchase, and permanent upgrade.
