ABB Modbus KNX Gateway

Strengthen the bonds, seamlessly.

The ABB Modbus KNX Gateway is a compact modular installation device for the integration of Modbus RTU servers and KNX TP devices. The Modbus RTU – KNX TP Gateway is a bidirectional gateway with 100 freely configurable data points. The device functions as a Modbus RTU client and makes it easy to integrate Modbus servers that support the RTU protocol via RS-485.

An optional, free-of-charge DCA is available to facilitate the configuration, allowing to export, and import Modbus-KNX mapping in the form of templates. Modbus component templates will also be available for download from a database.

Main Features Gateway

  • The device functions as a Modbus RTU client
  • Up to 100 Modbus data points
  • Up to 100 Modbus RTU servers
  • Up to 254 Modbus RTU addresses
  • Uses KNX standard data point types (DPTs)
  • The device is powered via the bus and requires no additional auxiliary voltage
  • Arithmetic and/or logical operations available for each data point via parameters
  • ETS (Engineering Tool Software) is used to parameterize the device
  • A Device Configuration App (DCA) is also available for easy configuration
  • Easy traceability via 2D-Code

Configuration as easy as saying...

Connect Modbus servers

Do the Modbus - KNX mapping once, you will be able to reuse it with other projects.

Import/export templates

Retrieve templates locally or from the online ABB database, save them within your most convenient directories.

Endless use

Mapping ready! You won’t need to start over each time, your templates will be always available for any future need.

DCA Available

An optional, free-of-charge DCA is available to facilitate the configuration.
