Compact gateway for small-scale Modbus to KNX integration projects

Home Engineering Automation & Control Compact gateway for small-scale Modbus to KNX integration projects

ROOM automation projects in commercial applications such as hotels or office buildings are often of small scale, only requiring a limited number of signals from HVAC and metering devices to be integrated into a KNX system. Here, integrators are often faced with connecting rooftop units, fan coils, or meters, but these typically come with Modbus RTU slave connectivity as standard.

HMS Networks is addressing this situation with the new Intesis Modbus RTU to KNX gateway, a cost-effective protocol converter that supports up to 100 data points.

Described as easy to install with a compact form factor, the gateway features Modbus RTU master functionality for seamless integration of any Modbus RTU slave to KNX.

With separate interfaces for KNX TP and serial Modbus RTU (RS485) respectively, it enables bidirectional data monitoring and control of the integrated data. Power is supplied by the KNX bus.

“Straightforward configuration using the standard ETS tool The Modbus RTU to KNX gateway can be configured with the ETS tool which makes configuration easy and seamless for the many KNX professionals who are using the ETS tool daily in their KNX projects,” the company said in a statement.

Users also benefit from the fact that the product database can be directly downloaded from the ETS catalogue and imported into the integration project.

To assist with integration to KNX, the gateway allows manufacturers to create pre-defined templates that match the Modbus register maps of their devices. With this, KNX integrators can integrate Modbus RTU slaves such as HVAC or metering devices into the KNX network very quickly, while maintaining full data control.

The gateway extends the range of existing Intesis KNX protocol translators and has been certified by the KNX Association.
