Multi-system BMS Gateway

Il problema

HVAC, lighting, access control, energy and fire systems each report to a different workstation, and operators cannot correlate an event across them.

Panoramica della soluzione

MILESGO gateways collect data from air handling units (AHU), KNX lighting actuators and panels, access control systems, electricity meters, fire alarm panels (read-only), IP cameras (RTSP) over Modbus TCP / BACnet/IP / KNX / OPC UA / SNMP, and deliver it to the BMS, WEB HMI panels, third-party platforms (HTTP API) as BACnet/IP / OPC UA / MQTT. Field equipment keeps its own protocol and control logic; integration is done by configuration and point mapping, not custom code.

Typical scope

  • air handling units (AHU)
  • KNX lighting actuators and panels
  • access control systems
  • electricity meters
  • fire alarm panels (read-only)
  • IP cameras (RTSP)

Protocol path

Modbus TCP / BACnet/IP / KNX / OPC UA / SNMP → BACnet/IP / OPC UA / MQTT

Implementation checklist for the project manager

  • Fire and life-safety systems are monitored read-only; control stays with the certified fire system.
  • Where equipment only offers a vendor API or cloud, confirm access rights, data rate and costs with the vendor before design.
  • Freeze the point list and protocol mapping with the client before ordering hardware.
  • If camera streams are included, check network bandwidth for RTSP-to-web viewing through the BMS gateway.
  • Keep OT networks segregated and use VPN for remote access instead of opening ports to the internet.
  • Define an alarm matrix (priority, recipient, escalation) and test every alarm end to end at SAT.
  • Hand over configuration backups, point table, IP plan and as-built drawings, with a short operator training.

Project deliverables

  • Signed point table and protocol mapping
  • Gateway configuration files and backups
  • IP address plan and network drawing
  • FAT and SAT test records
  • As-built documentation and operator training

Architettura del sistema

Field layer: air handling units (AHU), KNX lighting actuators and panels, access control systems, electricity meters, fire alarm panels (read-only), IP cameras (RTSP), connected over Modbus TCP / BACnet/IP / KNX / OPC UA / SNMP. Edge and integration layer: MILESGO protocol gateways and edge controllers, mounted on DIN rail in existing panels, polling each device, time-stamping values and buffering them locally. Upper layer: the BMS, WEB HMI panels, third-party platforms (HTTP API), which receives the data as BACnet/IP / OPC UA / MQTT. Remote access for maintenance runs over VPN rather than open internet ports.

Fasi di realizzazione

  1. 1

    Site survey and point list

    Inventory devices, protocols, register maps, panel space, power and network paths.

  2. 2

    Design and point table sign-off

    Map every point to the target protocol and system; agree it with the client and the upper-system contractor.

  3. 3

    Configuration and FAT

    Build the gateway configuration off site, simulate it and test against the signed point table.

  4. 4

    Installation and wiring

    Mount gateways on DIN rail, wire RS-485 / I/O / Ethernet, apply the IP plan.

  5. 5

    SAT and alarm tests

    Verify values against local readings, test every alarm and command end to end.

  6. 6

    Handover and support

    Hand over configuration backups, point table and as-built documents; train operators.

Valore per il cliente

  • One view of all subsystems instead of separate vendor consoles
  • Open interfaces (BACnet, Modbus, OPC UA, MQTT, HTTP) avoid lock-in to one vendor
  • New equipment integrated by configuration, not custom driver development
  • Alarms reach the right person by SMS, email or messaging apps
