More information
IP and DP parameters in non-volatile data
The IP and DP parameters are loaded from configuration data on the CompactFlash Card
during startup for use by the SIMOTION device. The SIMOTION D410 can use the
addresses defined in these data to go online. The IP and DP parameters on the
CompactFlash Card are also written to non-volatile memory during startup. The IP and DP
parameters in non-volatile data is retained and used by the SIMOTION device if the system
is restarted with a CompactFlash Card which does not contain any configuration data. The
SIMOTION device can always be made available online if the configuration was downloaded
to the device at least once using SIMOTION SCOUT, or if the SIMOTION device was started
up with Compact Flash Card.
