HD67714-MSTP-B2 BACnet MS/TP Master to Modbus TCP Slave Converter

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

HD67714 is a BACnet Master / Modbus TCP Slave Converter and it allows you to connect some BACnet slaves with a Modbus TCP Master (for example a PLC, HMI). Converter is easy to configure thanks to free SW67714 software. Compared with the slim housing type A, the housing type B provides a more robust casing and additional space for wiring, making it suitable for larger or more demanding installations. The device ensures stable and bi-directional communication between different automation systems, allowing building automation devices and industrial controllers to exchange data seamlessly. This is especially valuable in projects where BACnet-based HVAC or lighting systems must be integrated with Modbus TCP SCADA or PLC platforms.

Configuration:

Thanks to the SW67714 software on your PC you can:

• Define the parameters of BACnet line
• Define the parameters of Modbus TCP line
• Define the BACnet data that the converter reads/writes
• Update the device

The configuration software allows quick mapping of BACnet objects to Modbus registers, reducing integration time in projects with multiple field devices. Engineers can configure up to hundreds of objects without advanced coding. Built-in support for firmware upgrades ensures long-term compatibility with future updates of BACnet and Modbus standards.

Characteristics:

• Up to 512 BACnet objects in reading and 512 objects in writing
• Triple isolation between Serial - Power Supply, Serial - Ethernet, Ethernet - Power Supply
• Bi-directional information exchange between Modbus TCP bus and BACnet bus
• Mountable on 35mm Rail DIN

The ability to handle 512 objects per direction makes the device ideal for large automation systems with many data points. Triple galvanic isolation increases safety and protects equipment from surges and interference. Thanks to the robust type B housing, the converter is suitable for control cabinets where durability and safe cable management are required.
