KNX Modbus RTU Gateway, Modbus Server or Client, ETS Parameters for Setup
Product code:
5256
The KNX Modbus RTU Gateway 886 is a compact KNX/Modbus gateway with 250 freely configurable channels (KNX data points). The device allows easy integration of Modbus devices supporting the RTU protocol via RS-485 into KNX installations. It can be used as Modbus Server or Client.
Description
The assignment between KNX objects and Modbus registers is made via parameters in the ETS - no further tool is required. The configuration can also be exported and imported via a DCA (Device Configuration App, SW extension in the ETS).
The device enables the interpretation and scaling of the Modbus data according to the data point types of the KNX standard.
Two buttons and three multi-colored LEDs on the front panel allow local operation (test functions) and visualization of the device status. The Modbus connection is electrically isolated from the KNX bus. All connections are pluggable.
