Data deleted on memory reset
The following data is deleted during a memory reset:
● User data (programs, configuration data, parameterizations, task configuration)
● Technology packages
● Retain TO (absolute encoder adjustment)
● Retain variables
Retain variables are variables in the interface or implementation section of a UNIT that
are declared with VAR_GLOBAL RETAIN, or global device variables with the RETAIN
attribute.
Note
Absolute encoder data is deleted during a memory reset operation and must therefore be
readjusted after the memory reset.
Reset-proof data
The following data is retained during a memory reset:
● TCP/IP and DP parameters
● Diagnostic buffer
● Data that was saved with the _savePersistentMemoryData, _saveUnitDataSet,
exportUnitDataSet and RAMtoROM commands
If backup files (PMEMORY.XML/PMEMORY.BAK) have been backed up with
_savePersistentMemoryData, the data in these files is backed up again to the non-volatile
data after the memory reset. Users can therefore force the restoration of non-volatile data
by means of memory reset.
● Licenses
The technology packages and user data (configuration data, programs, parameterizations)
that were previously backed up to the micro memory card using the "Copy RAM to ROM"
menu command will be transferred to the "non-volatile data" area of the SIMOTION C during
the next ramp-up. Thus, an existing configuration on the MMC is loaded to the SIMOTION
device following the memory reset.
Memory reset by means of SIMOTION SCOUT
1.
In SIMOTION SCOUT, select the "Target system" > "Control operating mode" menu
command.
The dialog "C2xx: operating mode" is opened.
2.
Select MRES mode to perform the memory reset.
