Description
The BACnet to OPC UA Gateway enables BACnet-based Building Automation Systems (BAS) to seamlessly exchange data with OPC UA-based industrial automation, enterprise-level systems, and Internet of Things (IoT) platforms.

Key Features

Universal Protocol Conversion

  • Downlink Support: BACnet/IP, BACnet MS/TP, Modbus RTU/TCP Master
  • Uplink Support: OPC UA (seamless integration with cloud/SCADA systems)
  • Modbus RTU↔TCP transparent transmission for protocol interoperability

Powerful Edge Computing

  • ARM MCU @300MHz + Linux OS
  • Connect 10/50 devices & collect 512/4000 data points simultaneously
  • Hardware/software watchdog for 24/7 reliability

Flexible Connectivity
  • Dual Ethernet Ports: 1×WAN + 1×LAN (10/100M auto-adaptive), supports cascaded switches
  • Serial Ports: 2 or 6×RS485/RS232 (customizable baud rate/parity)
  • WiFi Option: Dual-band 2.4G/5G support


Typical Applications

Smart Buildings: Integrates BACnet HVAC/Modbus meters into unified Building Automation (BA) systems
Industrial IoT: dge computing for data pre-processing to reduce cloud load
Energy Monitoring: Collect real-time meter data for control centers
