HD67674-MSTP-A1 BACnet MSTP Slave to Modbus TCP Slave converter, DIN slim housing

Industrial BACnet MSTP Slave to Modbus TCP Slave converter, housing type A (slim), DIN rail mount.

The HD67674-MSTP-A1 converter is a compact and reliable solution designed to integrate a BACnet Master (such as BMS systems, HVAC controllers, or supervisory systems) with a Modbus TCP Master (PLC, SCADA, or other industrial controllers). It provides a stable bi-directional communication bridge between two widely used automation protocols, enabling seamless data exchange in building automation, industrial monitoring, and energy management systems. Thanks to its slim housing type A, the device is ideal for installations with limited space, such as compact control cabinets. The DIN rail 35 mm mounting ensures quick integration into both new and existing industrial panels. Configuration and maintenance are simple and efficient through the free SW67674 software, which allows full control over communication parameters and object mapping.

Configuration:

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

• Define detailed BACnet MS/TP communication parameters (baud rate, address, parity, etc.)
• Configure Modbus TCP parameters such as IP address, port, timeout, and device mapping
• Create BACnet objects that represent data received from the Modbus TCP Master
• Assign BACnet objects that transmit control information back to the Modbus network
• Update firmware and apply changes remotely without physical intervention
• Use integrated diagnostic tools to monitor traffic and debug communication issues in real time

This user-friendly configuration environment greatly reduces commissioning time and ensures compatibility across diverse installations.
