Page 4: Task
1 Task Task Introduction Gateways enable communication between two networks/bus systems that use different communications protocols. KNX is a fieldbus for building automation. Technically, KNX is the successor to the European Installation Bus (EIB), adding communication mechanisms and transmission media. The functionality of a KNX system can be extended by integrating an S7 CPU into a KNX system via a gateway. -

Page 10: Mode Of Operation
3 Mode of Operation Mode of Operation The data between the two bus systems, PROFINET and KNX, is exchanged between the drivers (PROFINET, KNX) in the gateway via data point mapping. The data points are described in the pnetd1.txt and eib1.txt configuration files and mapped to each other in the dispatch.txt dispatch file. -
Page 11: Data Point Mapping
3 Mode of Operation Data point mapping The following figure shows all of the data used and the process image of the S7- 1200 CPU for the configuration with the gateway. Please note: The input or output signal type always refers to the “perspective” of the respective device. -
Page 12: Correlation Of The Gateway Configuration Files
3 Mode of Operation 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. - Page 13 3 Mode of Operation In the gateway configuration files, KNX objects are identified by “eib…” and Note PROFINET objects are identified by “pnetd…”. This application example describes how to edit and customize these files so that they can be used for data exchange (see Chapter 4.4 Gateway: Editing configuration files).
