TH LINK PROFINET - Installation Manual
2.3 SD card
TH LINK disposes of an SD card slot (refer to Connections and
display elements [7]). You can save data on the SD card to have the
data available even after voltage recovery. You can find a list of
recommended SD cards in Release Notes on your installation CD
or in the Softing download area (
http://industrial.softing.com/en/
downloads.html ).
1. Insert the SD card before installing the device or putting it into
operation. Thus you make sure the card is recognized during
boot procedure.
2. Now go to TH LINK Settings TH SCOPE and set the
parameter Data restore after voltage recovery to Yes (see
also TH SCOPE ).
3. Following the initial device commissioning the SD card is
formatted automatically. From this time on you can save data
independently from power interruptions.
Note
If the SD card is not recognized during boot procedure,
restart the TH LINK.
Note
If the device power supply is interrupted, all previously
saved data will be retained on the SD card. Following a
device restart the data will be read. In case the TH LINK
detects a faulty file system or no existing TH LINK structure
during startup, the card will be formatted again. The
position of the blocking switch at the left card border has no
effect, i.e. the card will also be formatted or written in the
blocked state.
