In building automation and energy management, a long-standing technical challenge is the diversity of protocols used by field devices. HVAC systems may use BACnet/IP, lighting control systems may use BACnet/MSTP over RS485, while electricity and water meters typically use Modbus. Deploying dedicated gateways for each protocol would not only be costly but also make system maintenance and data analysis difficult due to fragmented data. Tespro's TG-100 intelligent edge computing gateway offers a simple and efficient solution through multi-protocol integration. The gateway supports Modbus RTU, BACnet/IP, and BACnet/MSTP, connecting to different types of field devices either simultaneously or selectively, then uploading unified data to cloud platforms or third-party servers via MQTT, TCP, or UDP.
The practical value of the TG-100 in building automation scenarios is outstanding. Consider a medium-sized commercial complex requiring monitoring of hundreds of fan coil units, dozens of air handling units, lighting circuits across multiple floors, and all tenant electricity meters. A traditional approach would require separate BACnet and Modbus gateways, with two independent systems and no correlated data analysis. The TG-100 connects BACnet air handling controllers and Modbus meters simultaneously, correlating air conditioning operation data with electricity consumption at the gateway level for joint analysis of energy use and equipment status. The gateway supports both BACnet/IP and BACnet/MSTP variants, connecting to BACnet/IP devices over Ethernet and BACnet/MSTP field devices over RS485, covering the complete communication range from management layer to field layer in building automation systems.
Which building automation protocols does the TG-100 intelligent edge computing gateway support, and can it connect both BACnet and Modbus devices simultaneously?
The TG-100 supports Modbus RTU, BACnet/IP, and BACnet/MSTP, connecting to different types of field devices either simultaneously or selectively. A single gateway collects data from both BACnet air handling controllers and Modbus meters for unified management of building equipment and energy metering.
Beyond protocol compatibility, the TG-100 offers flexible communication interface configuration. The gateway provides one field communication interface configurable as RS485, RS232, or CAN based on project requirements, with RS485 particularly suitable for connecting BACnet/MSTP buses and Modbus RTU devices. The gateway also features one WAN port and one LAN port, connecting to cloud platforms via WAN and to local BACnet/IP networks via LAN. For projects requiring building data integration with higher-level management platforms, the TG-100 supports TCP, UDP, and MQTT network transport methods, connecting to various cloud platforms or third-party servers. The gateway also supports SSL encrypted transmission, securing building automation data during public network transmission. For system integrators and building operations teams, choosing the TG-100 means covering both building automation and energy monitoring scenarios with one device, simplifying system architecture and reducing long-term operational costs.
