HD67673-MSTP-B2 BACnet MSTP to Modbus TCP Master converter, DIN rail, wide housing

Industrial BACnet MSTP Slave to Modbus TCP Master converter, housing type B (wide), DIN rail mount.

HD67673-MSTP-B2 is a reliable industrial protocol converter that allows seamless connection between a BACnet Master (such as a Supervisory System, BMS, or PLC) and multiple Modbus TCP slave devices. It acts as a bridge between building automation and industrial control networks, ensuring stable, bi-directional data transfer. With its robust type B housing (wide version) and DIN rail mount design, the device is ideal for integration in both new and existing automation cabinets. Configuration is made simple using the free and user-friendly SW67673 software, which provides advanced options for mapping, diagnostics, and firmware updates.

Configuration:

Using the SW67673 software on your PC, you can:

• Define and fine-tune the parameters of the BACnet MS/TP line (baud rate, parity, station address, etc.)
• Configure Modbus TCP communication parameters (IP addressing, port number, response times)
• Create BACnet objects that contain the data read from Modbus TCP slaves
• Map BACnet objects that will send commands or values to Modbus TCP slaves
• Perform firmware updates directly from the software
• Access diagnostic tools to monitor real-time communication and detect possible network issues

The configuration tool also allows saving and reusing templates, making the management of large installations more efficient.

Characteristics:

• Supports up to 1024 BACnet objects (Read + Write)
• Triple galvanic isolation between BACnet – Power Supply, BACnet – Modbus, Power Supply – Modbus
• Stable bi-directional data exchange between BACnet and Modbus networks
• Housing type B (wide) designed for cabinet installations where more wiring space is needed
• DIN rail 35mm mount for quick and secure integration
