Device functions
The 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.
4.2
Software functions
The software application Engineering Tool Software (ETS) is used for physical address assignment and
parameterization.
Each server has its own parameter window. A user-friendly table in ETS allows you to make assignments
between Modbus registers and KNX Group Objects.
The gateway uses KNX standard data points (DPTs) to ensure smooth integration.
Additional functions (arithmetical and logical operations) are available for each data point.
There is also a device configuration app (DCA) available to make configuration easier by allowing you to
import and export device templates.
There is a comprehensive database of ready-made templates available for import.
The DCA is also used for firmware updates.
