EZ Gateway KNX to BACnet

Connect to the cloud and interface KNX certified products to BACnet management systems

EZ Gateway KNX to BACnet

The EZ Gateway KNX to BACnet (FS-EZX-KNX-BAC) is an easy-to-use, high-performance building and industrial automation IIoT gateway for integrators to connect to the cloud and interface KNX certified products to BACnet management systems in commercial buildings, campuses, and industrial facilities. KNX-certified products encompass a wide range of applications such as lighting control, heating, ventilation and air conditioning control, shutter/blind and shading control, alarm monitoring, energy, gas, and water metering, and audio and video distribution. The EZ Gateway KNX to BACnet integrates such KNX-based devices and systems to both flavors of BACnet-based management systems over BACnet MS/TP or BACnet/IP protocols. KNX to BACnet protocol translations include:

  • KNX to BACnet/IP
  • KNX to BACnet MS/TP
High-performance building IIoT gateway

The EZ Gateway KNX to BACnet is available in 500 and 1000 point count configurations with superior network response times. With the EZ Gateway KNX to BACnet, the integrator or contractor can rely on the product’s interoperable and field-tested protocol implementation, and does not need to be a protocol expert. The integrator can also minimize configuration and commissioning time, while also reducing ongoing operating and maintenance costs.

1. SMC Device Cloud support

Register your EZ Gateway to the SMC Cloud interface for remote access to local applications, configuration, and device management

2. KNX Interoperability

Connect with virtually any KNX-certified device out of the box

  • ETS Support: Seamlessly import KNX Group addresses from ETS to lower commissioning time
3. BACnet COV

Use the Change of Value (CoV) setting to reduce the amount of BACnet data overhead to allow network traffic to be less congested by transmitting data only when detecting a KNX device status has changed

4. DeviceProxy™

Minimize management and operational costs with granular visibility and control over each KNX device from a BACnet management station

5. Remote Access and Support

All FieldServer gateways come with Remote Access support.  Once registerd to the SMC Cloud, use the Remote Access capability to attach to the FieldServer gateway to monitor, maintain and troubleshoot installed equipment
