3.3 Correlation of the gateway configuration files
The gateway is configured using various configuration files (cfg, txt files). Once
programming is complete, these files are uploaded in a text editor (for example,
Notepad++) using the integrated web server in the gateway or directly edited and
enabled in the integrated web server. A configuration check is performed in the
gateway and any errors are displayed.
As the gateway supports different bus systems (PROFINET, KNX, BACnet…),
there are different driver files with protocol information (files with the .cfg extension)
and a file with the definition of the data points (.txt extension).
The dispatch file (dispatch.txt) is an integral part. It contains the mapping of the
data points of the different protocols to each other.
The data points are programmed as objects. For the exact meaning and structure
of these files, please refer to the gateway manual (\3\). The gateway data backup
cfg and txt files also contain this information as comment lines.
For the complete configuration, please refer to the supplied “ugwbackup.tgz”
gateway data backup in the “ugw > config” folder and the included comments
(109740160_KNX_Gateway_RestoreFile_Vxx.zip).
