10.1 Configuration in KNX S-Mode
After installing the controller and the web server, the plant is commissioned as
follows:
 Plant commissioning via ETS (addressing and S-Mode binding)*
 Controller commissioning with ACS*
 Web server commissioning via web browser or ACS
 Generate web pages on the web server.
* Both tools include parameters for RDG/RDF controllers, but ETS can only write.
Reset is only possible with ACS790. The tool sequence is important to ensure a
valid configuration and backup: First ETS and then ACS.
The ETS software permits planning and commissioning of KNX
installations of all sizes.
ETS is a registered trademark of the KNX Association
(www.knx.org) and can be purchased and downloaded via its
website. Product data for OZW772... is compatible with ETS as
of version 4 and 5.
In ETS, the actual building (apartments, rooms), including all KNX devices and
wiring structures are mapped virtually. Sensors and actuators are connected as
desired.
The finished configuration is saved as a project and loaded to the web server and
other participating devices.
Sensors and actuators are mapped as data points.
The format and number of bits, bit coding, value range and, where required, the
unit (°C, %, m3/h, etc.) are specified in each data point type.
KNX S-Mode data points receive, with ETS, all attributes needed so that only the
web page can be generated with the web browser.
A maximum of the following data points can be used depending on the device type:
 OZW772.01 7 DP
 OZW772.04 237 DP
 OZW772.16 237 DP
 OZW772.250 237 DP
A data point can be used multiple times but then is also counted multiple times.
The web server supports 10 KNX S-Mode pages that can be used to place the data
points.
Any number of data points can be used per page as long as the maximum number
of usable data points is not exceeded.
An update takes up to 70 second for 237 S-Mode data points on the same page.
We recommend grouping the data points in a logical manner and spreading them
out over various pages.
