HD67674-MSTP-B2 BACnet MSTP to Modbus TCP Slave Converter – Type B housing

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

HD67674-MSTP-B2 is a professional industrial converter designed to ensure seamless data exchange between BACnet MSTP Master devices (such as building management systems, HVAC controllers or Supervisory Systems) and Modbus TCP Master systems (for example PLCs or SCADA platforms). It enables bi-directional communication between the two networks, eliminating protocol incompatibility and providing a stable and secure data transfer channel. The device is housed in a type B enclosure, making it suitable for environments that require increased mechanical robustness and reliability. With its DIN rail 35 mm mount, installation is fast and straightforward, even in crowded control cabinets. Configuration is carried out via the free SW67674 software, which offers intuitive tools for setup and diagnostics, reducing commissioning time and simplifying integration into industrial and building automation projects.

Configuration:

With the SW67674 software installed on your PC, you can easily:

• Define all key BACnet MSTP line parameters such as baud rate, parity, address and communication settings
• Set Modbus TCP network parameters including IP address, port and communication timeout
• Create BACnet objects that contain data sent by the Modbus TCP Master
• Create BACnet objects that send data to the Modbus TCP Master
• Update device firmware and reconfigure the converter remotely
• Use built-in diagnostic tools to monitor communication and detect faults faster

This configuration flexibility allows the converter to be tailored to a wide variety of automation scenarios.
