Description

To the download area for the HVAC KNX Library with demo project

To purchase you must register in the CODESYS© Store. Without purchasing a license (download only) the HVAC KNX Library SL runs for 30 minutes without functional limitation (demo).

The HVAC KNX Library (HVACKNX) allows KNX IP data to be retrieved directly from the program via KNX IP interfaces using UDP. For this, the master block is placed and the individual group address blocks are linked to the master.

The following KNX IP interfaces have been tested with the library. Other untested interfaces may also be compatible.

Manufacturer	Device	Notes
ABB	IPS/S 3.1.1
SIEMENS	SWG1 148-1AB22
MDT	SCN-IP000.03

Below you will find an overview of the different KNX data types. This helps you choose our function blocks. Each group address also has a data type assigned. This must match the function block.

KNX datapoint type	Data	Function	Example values
DPT 1.yyy	1 bit	Switch	[0] = Off | FALSE / [1] = On | TRUE
