WARNING!
Data loss - card removal only when the power supply is switched
off!
Only remove the Yaskawa SD card when the power supply of the CPU is
switched off. Otherwise this will lead to data loss!
General notes on using the Yaskawa SD card
– Only Yaskawa SD cards are supported.
– The cards are pre-formatted (ext4 format) for use in CPUs of the
iC9200 Series.
– When formatting again, certain information on the Yaskawa SD card
that is required for use in the CPUs of the iC9200 Series will be lost.
– Exclude the Yaskawa SD card from being formatted.
– The Yaskawa SD card can be read at any time with a conventional
SD card reader. Sensitive data on the Yaskawa SD card can be read
if you do not physically protect it from unauthorized access.
– Make sure that unauthorized persons cannot access the Yaskawa SD
card.
Please note when using without an Yaskawa SD card!
– By default, support for the Yaskawa SD card is enabled.
– Disable the support of the Yaskawa SD card if you want to operate
the CPU without YaskawaSD card.
– If the support of the Yaskawa SD card remains enabled and the CPU
is operated without a Yaskawa SD card, there is a risk of data theft or
data manipulation.
– Unauthorized persons may insert a Yaskawa SD card and restart
the CPU.
– If a new, unused Yaskawa SD card is detected after PowerON,
the overlay file system with user program, configurations, user
data and firmware adjustments, is moved from the internal para-
metrization memory to the Yaskawa SD card and deleted in the
internal parametrization memory. Projects and IP configurations
saved there are then no longer available!
– When changing to operation without Yaskawa SD card, the overlay
file system of the internal parametrization memory is activated by the
CPU after PowerON and is used now. Please note that no data are
used from the Yaskawa SD card. There is also no function for trans-
ferring back from the Yaskawa SD card to the internal parametrization
memory.
The Yaskawa SD card has the following labelling and elements:
