If the real-time clock backup time is exceeded, the time is reset.
Note
IP and DP parameters in non-volatile data
The
IP and DP parameters are loaded from configuration data on the CF 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 CF 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 CF card which does not
contain any configuration data. Thus, the SIMOTION device can continue to go online if a
configuration was loaded with SIMOTION SCOUT at least once or if the SIMOTION device
is powered up with a CF card containing a configuration.
Volatile SIMOTION data (RAM / current RAM)
The volatile SIMOTION data is defined by the following properties:
●
The volatile SIMOTION data is located in the RAM memory of the SIMOTION device.
● The download data of SIMOTION SCOUT is written to this memory.
● These data is lost after the SIMOTION D410 is shut down.
● The "volatile SIMOTION data" area contains the following data:
– SIMOTION Kernel
– Technology packages (TP)
– User data (programs, configuration data, parameter settings)
