Ethernet or Wireless WiFi Communication Module MODBUS RTU(RS232/RS485) to MODBUS TCP

BCNet-MB is an economical Ethernet communication processor, which is designed to meet the increasing information requirements of factory equipment (equipment network monitoring and production management), and is used for Ethernet data acquisition (Modbus RTU/ASCII to Modbus TCP), it is very convenient to build a production management system.

The ModbusASCII/RTU master station can communicate with ModbusASCII/RTU devices through the multiplex interface, supports most SCADA software in the field of industrial control, and supports ModbusTCP and ModbusUDP communication methods.

BCNet-MB Features

Installed on a 35mm guide rail, directly connected to the RS485/RS232 interface of the Modbus RTU/ASCII device through a communication line, and connected to an external 24VDC power supply.

Integrate a WEB server, through the web page, you can set device parameters and run diagnosis, and set a login protection password to prevent tampering with configuration data.

This product is suitable for the network upgrade of Modbus RTU/ASCII, and can cooperate with the configuration software of the host computer supporting Modbus TCP to directly read the data of the device through this module.

Support asynchronous and uninterrupted Modbus TCP access mode, which is different from the traditional master-slave response half-duplex mode, providing more efficient data access. That is, the client’s Modbus TCP request can send multiple Modbus TCP requests at the same time without waiting for the reply from the device, and the module will automatically and asynchronously reply to the response frame.

The serial port supports RS485 and RS232 optional, and the baud rate supports 9600bps~115200bps optional.

2KV surge protection, ESD electrostatic protection, high-strength anti-electromagnetic interference.

When connected to Modbus RTU/ASCII slave station, multiple PCs are allowed to collect PLC data at the same time, and the real-time and reliability of data communication is fully guaranteed.

Support firmware update on the user side through Ethernet, provide firmware with more functions for free, purchase hardware once, and upgrade permanently.

BCNet-MB-S is used for Ethernet data acquisition of ModbusASCII/RTU equipment (instrument, inverter, PLC, etc.), the module integrates WiFi function, supports AP mode, STA mode and AP+STA mode, which is very convenient to build WiFi network, directly ModbusASCII/RTU device programming and data acquisition via WiFi.

BCNet-MB-S adopts the plug-and-play design, which does not occupy the communication port of the ModbusASCII/RTU device, that is, while the programming software/host computer software monitors the device data through Ethernet, the ModbusASCII/RTU master station can communicate with the device through the multiplexing interface. ModbusASCII/RTU equipment for communication, supports most SCADA software in the field of industrial control, and supports ModbusTCP and ModbusUDP communication methods.

BCNet-MB-S Function

Installed on a 35mm guide rail, no external power supply required. The COM1 port is connected to the RS485 port of the device, and the COM2 expansion port is used for Modbus master communication.

Through the WEB server or the configuration diagnostic tool BCDevice, the device can be parameterized and run diagnostics.

It is suitable for the network upgrade of ModbusASCII/RTU, and the data of the device can be directly read through the configuration software of the host computer that supports ModbusTCP.

Integrated WiFi function, support AP mode, STA mode and AP+STA mode.

RS485/RS232 device data collection can be carried out through WiFi or Ethernet.

Support asynchronous and uninterrupted ModbusTCP access mode, which is different from the traditional master-slave response half-duplex mode, providing more efficient data access. That is, the client’s ModbusTCP request can send multiple ModbusTCP requests at the same time without waiting for the reply from the device, and the module will automatically and asynchronously reply to the response frame.

Support ModbusTCP, ModbusUDP, ModbusRTU and ModbusASCII communication protocols, support various configuration software and OPC, and access device data through Modbus protocol.

Using ModbusTCP/UDP, it 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.

Support 32 ModbusTCP client connections.

Support firmware update on the user side through Ethernet, one purchase, permanent upgrade.
