Four Protocols. One Controller. — BACnet/IP + MQTT + Modbus TCP + OPC UA for smart buildings.
Modern buildings are no longer just about HVAC. They connect to cloud platforms for energy analytics. They integrate with IT systems for facility management. They talk to legacy Modbus equipment. And they must speak BACnet/IP to the central BMS.
Supporting all of this usually means multiple gateways, complex integrations, and high costs.
The BA190Pro changes everything. It supports four uplink protocols in a single device — BACnet/IP for BMS, MQTT for cloud, OPC UA for IT systems, and Modbus TCP for legacy integration. One device. Every protocol you need. Built‑in I/O expansion. Local logic. Wide temperature operation.
Think of it as your smart building edge controller — ready for today's BMS and tomorrow's cloud‑based facility management.
Supports BACnet/IP (for building management systems), MQTT (for cloud platforms), OPC UA (for IT/OT integration), and Modbus TCP (for legacy equipment and SCADA). Enable one, two, or all four simultaneously. Your building data — collected via Modbus RTU/TCP or local I/O — is available through every enabled protocol.
Standard BACnet/IP server. Your Siemens, Honeywell, Johnson Controls, or Distech BMS discovers the BA190Pro like any other BACnet device. Modbus and local I/O data are exposed as standard BACnet objects.
Publish building data — temperatures, energy consumption, equipment status — directly to Alibaba Cloud, AWS IoT, Huawei Cloud, or ThingsBoard. Enable cloud‑based facility management and energy analytics.
X.509 certificates, AES-256 encryption, role‑based policies. Connect your building data to enterprise facility management systems, smart city platforms, or digital twins.
Your existing Modbus TCP equipment integrates natively. No additional gateways. No protocol conversion layers.
Connect local sensors and actuators directly. Digital, analog, RTD temperature, pulse — all available. Local I/O data is exposed through all four uplink protocols automatically.
Set up IF-THEN rules, schedules, and conditional actions through the web browser. The BA190Pro continues to control your building even when the network is down.
Remote firmware upgrades and parameter configuration are built in. Update devices in the field without sending a technician. Reduce downtime. Lower service costs.
You are building a smart building that requires BMS integration (BACnet/IP), cloud analytics (MQTT), and IT system connectivity (OPC UA). Stock one device — BA190Pro. Configure the protocols per requirement. Simplify your design. Reduce your equipment count.
Your building data needs to go to three places — the local BMS for operations, the cloud for energy analytics, and the enterprise IT system for facility management. BA190Pro publishes the same data through BACnet/IP, MQTT, and OPC UA simultaneously. One device. Three audiences.
Manage multiple buildings from a central cloud platform while maintaining local BMS control at each site. BA190Pro at each building — local BACnet/IP for on‑site BMS, MQTT or OPC UA for central cloud monitoring. Best of both worlds.
Existing building has a BACnet BMS. But the owner also wants cloud monitoring and IT system integration. Instead of adding multiple gateways, deploy BA190Pro. It talks to the existing BMS via BACnet/IP while simultaneously publishing to cloud and IT systems.
Your air handling unit, chiller, or lighting panel needs to integrate with multiple building systems. Build BA190Pro into your equipment. It speaks BACnet/IP to BMS, MQTT to cloud, OPC UA to IT. One integration covers all requirements.
| Protocol | Primary Use | When to Enable |
|---|---|---|
| BACnet/IP | Building Management System (BMS) | Local building control, HVAC sequencing, lighting schedules, alarm management |
| MQTT | Cloud platforms, IoT dashboards | Energy analytics, remote monitoring, facility dashboards, cloud‑based alarms |
| OPC UA | IT systems, enterprise integration | Smart city platforms, digital twins, enterprise facility management, security compliance |
| Modbus TCP | Legacy equipment, SCADA | Existing Modbus devices, backup monitoring, third‑party equipment integration |
