7.16 Deleting data
● 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 are deleted during a memory reset and must therefore be readjusted
after the memory reset.
Data retained during memory reset
The following data are retained during a memory reset:
● TCP/IP and DP parameters
● Diagnostic buffer
● Data that was saved with the _savePersistentMemoryData, _saveUnitDataSet or
_exportUnitDataSet commands and with the "Copy RAM to ROM" function.
If backup files (PMEMORY.XML/PMEMORY.BAK) have been created with
_savePersistentMemoryData, the data in these files will be backed up again to the non-
volatile SIMOTION data after the memory reset. Users can therefore force the restoration
of non-volatile SIMOTION data by means of memory reset. This also includes the absolute
encoder position.
● Licenses
● SINAMICS NVRAM data
The technology packages and user data (configuration data, programs, parameter
assignments) that were previously backed up on the CF card using the "Copy RAM to ROM"
menu command will be transferred to the "non-volatile SIMOTION data" area of the
SIMOTION D410-2 during the next power-up. Thus, an existing configuration on the CF card
is loaded to the SIMOTION device following the memory reset.
Memory reset by means of SIMOTION SCOUT
The SIMOTION device for which overall reset is to be performed must be online.
1. Open the "Control Operating State" dialog box in SIMOTION SCOUT. Select the "Target
system" > "Control operating state" menu command. Or click on "Control Operating State"
on the toolbar.
2. Switch the SIMOTION device for which memory reset is to be performed to STOP in the
"Control Operating State" dialog box.
3. Select the SIMOTION device under "Memory reset (MRES)." Click the "Run" button.
Confirm the command by clicking "Yes."
The memory reset will now be performed.
