Using the Data Logger Function of the Gira IP Router or S1

The GIRA IP Router and S1 Remote Access device have an additional ability to record the KNX bus telegrams to a memory card. This is a useful feature when troubleshooting an installation or returning to site after an absence as it can be set to constantly record.

To enable this you need to make sure you have the latest application version for either device.  In the case of the IP Router it is also required to download the "KNX/IP router and router applications" application (previously called- data logger / clock).

In the parameter pages of the application you can enable the data logger and define the behaviour once the memory card is full. It can either overwrite the oldest recorded telegrams or stop recording and send a message on the bus notifying you it has reached capacity.

On the device is a slot for a Micro SD card which needs to be formatted as FAT32 and not bigger than 32GB.

Once recording has taken place, by logging into the web interface of the S1 or IP Router it is possible to export the log files without removing the memory card from the device - this is particularly useful if working on a remote connection away from the site.  Alternatively one can stop the recording, remove the memory card and extract the log using a standard card reader.  The required XML log file(s) can be imported into ETS within the group monitor.

One consideration is there are no settings to limit the size of the log. A 32GB memory card could hold in excess of 200 million telegrams. Using a smaller memory card is advised to prevent ETS failing to load the log file.
