Building Management
Integration protocols and configuration guides for connecting KNX building automation to BMS platforms, covering OPC UA and BACnet/IP gateways, Siemens Desigo CC driver setup, and ISO 50001 energy reporting from KNX Modbus sub-metering.
KNX to BMS Integration: OPC UA, BACnet and KNXnet/IP Gateways
Integration paths for connecting KNX bus to building management systems: KNXnet/IP tunnelling, BACnet/IP gateways (Intesis IN701KNX300000, LOYTEC LKNX-100), OPC UA servers (Lingg and Janke KNX Virtual, HMS Anybus), and Modbus TCP bridges. Covers data point selection, ETS6 export for BMS import, alarm routing and trend logging strategy for commercial buildings above 5,000 m².
Siemens Desigo CC and KNX: Driver Configuration and Data Points
Step-by-step configuration of the Desigo CC KNX Driver plugin: ETS6 OPC DA export and import, point browser review, alarm rules with SMTP escalation, floor plan graphics with live KNX values, trend logging intervals for energy and temperature circuits, and per-point licensing guidance for Desigo CC Flex and Compact Edition.
ISO 50001 Energy Reporting from KNX Modbus Metering
Implementing ISO 50001:2018 energy management using KNX sub-metering: Carlo Gavazzi EM340 Modbus meters via WAGO gateway to KNX group addresses, energy baseline from 12-month BMS trend data, EnPI calculation (kWh/m², kWh/degree-day), weather normalisation with CODESYS degree-day program, significant energy user identification, monitoring and measurement plan documentation, and audit evidence for third-party ISO 50001 certification.
Need KNX panels integrated with your BMS platform?
We design and build KNX panels with BACnet/IP and OPC UA gateway integration pre-configured, ETS6 group address exports ready for BMS import, and full as-built documentation for ISO 50001 metering system evidence.
