The Modbus KNX Gateway integrates Modbus RTU servers devices with KNX installations at field level. The devices support standard KNX data points (DPT) and up to 100 Modbus data points. The device is put into operation with the ETS. An optional, free-of-charge ETS-App (DCA) is available to facilitate the configuration, allowing to export, and import Modbus-KNX mapping in the form of templates. Modbus templates are available for download from a database. Auxiliary voltage is not required.
