6.2 Relay contact
With the relay contact it is possible to react on an event (retries, lost, bus voltage too low, etc). It is also
possible to control the relay manual or on a timer. Refer to Paragraph 4.7 for details. The relay is capable of
switching 0.5 A - 24 VAC.
6.3 SD card
The SD card is used to store ProfiTrace file recording data, logs, the GSD info file and backup settings.
By default a 1 GB SD card is supplied together with the Head Station, but it can be exchanged by an SD card
with a maximum size of 32 GB.
The SD card is addressable directly with an FTP client. In the FTP software the SD card has a drive letter with a
directory structure, on which files can be read and written from and to the SD card. When the password is set
in the web server, this same password has to be used by the FTP software to establish a connection.
6.3.1
Inserting/replacing the SD card
The socket is located on the front plate of the Head Station.
To remove the SD card, gently press it inwards. The SD card is unlocked and released from the socket.
With insertion, just insert the SD card in the socket and press it inwards. The SD card socket has a polarity to
make sure it is not inserted backwards.
The SD card is hot swappable, but there is a risk that
monitoring data is lost when the system wants to write
at exactly the same time as the removal or insertion.
