EZ Gateway KNX to BACnet

The Quick and Easy KNX to BACnet Solution

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

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.

Accessing the EZ Gateway Through FieldPoP

Enjoy the benefits of the cloud connectivity through FieldPoP™. The EZ Gateway KNX to BACnet is FieldPoP-enabled, meaning all EZ Gateways can be registered to FieldPoP, Sierra Monitor’s device cloud for the IIoT.

The FieldPoP web interface lets users remotely access, in a secure fashion, the FS-GUI and configuration web applications that are available locally on the EZ Gateway. These applications offer functionality for configuration, monitoring, logging, security, diagnostics, and updates.

Fastest Network Response Time

The EZ Gateway supports BACnet COV (Change of Value), which provides a fast response time to the BACnet network when the status of the KNX device changes. By implementing BACnet COVs, only necessary and vital data is transmitted across the BACnet network, thus reducing the amount of BACnet data overhead to allow network traffic to be less congested.

Interoperable and Field Tested Protocol Implementations

The EZ Gateway KNX to BACnet combines field-hardened KNX and BACnet protocol drivers with an easy to use configuration interface. As a member of the KNX Association, we consistently implement the latest KNX innovations on our FieldServer protocol gateways and test them thoroughly for interoperability. The EZ Gateway’s KNX interface implements a large number of KNX data types and is compatible with all KNX-certified products, while the EZ Gateway’s BACnet interface has been certified by BACnet Test Laboratory (BTL), at Version 12.

Lowest Commissioning, Ongoing Management, and Operation Costs

The intuitive web-based interface allows configurations to be built in the field or in the office, thereby simplifying the commissioning and integration process. The EZ Gateway also supports ETS, the KNX configuration software tool. The EZ Gateway can seamlessly import KNX addresses from ETS to lower commissioning time.

DeviceProxy™, our unique device management feature, is the ability to represent each KNX device as a corresponding virtual BACnet device on the FieldServer EZ Gateway. This grants the integrator granular visibility and control over each KNX device from a BACnet management station (example: offline/online status is visible at the individual KNX device). With the ability to manipulate virtual BACnet device instances, reconfiguration of the network such as adding or removing devices, becomes extremely simple.

The DeviceProxy feature also provides easy troubleshooting during device commissioning or during runtime. In the event a connected KNX device goes offline, only the corresponding BACnet device is shown offline at the BACnet management station, rather than the entire gateway being shown offline.

Certifications & Approvals

The EZ Gateway KNX to BACnet is approved across a variety of standards, including the UL 916, CE, and RoHS. The EZ Gateway also carries BTL Certification to Revision 12, assuring users that it correctly implements the BACnet features claimed. These approvals and certifications, along with our commitment to KNX interoperability, assure our customers that we carry only the highest quality of standards-compliant products.
