HD67714-MSTP-A1 BACnet MS/TP Master to Modbus TCP Slave Converter

Industrial BACnet MSTP master to Modbus TCP slave converter, housing type A (slim), 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). The device is designed to provide reliable, bi-directional communication between heterogeneous automation networks, ensuring that legacy BACnet MS/TP devices can seamlessly interact with modern Modbus TCP infrastructures. This makes it particularly useful in building automation, energy management and industrial control systems where interoperability is critical. Converter is easy to configure thanks to free SW67714 software, which reduces installation time and eliminates the need for additional programming.

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 utility offers an intuitive interface that enables engineers to map BACnet objects to Modbus registers with just a few clicks. This functionality greatly simplifies integration in projects where large amounts of data, such as temperature readings, energy consumption, or alarm states, must be exchanged between different systems. The ability to perform firmware updates directly via the software ensures that the converter remains compatible with evolving standards and customer requirements.

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

These characteristics make the HD67714 a powerful tool for system integrators. By handling a large number of BACnet objects, the device supports complex installations such as multi-zone HVAC systems, lighting controls, or energy monitoring networks. Triple galvanic isolation improves system safety, protecting both field devices and supervisory controllers from electrical disturbances. The compact DIN rail housing allows simple integration into control panels where space optimization is essential.
