●
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
As a memory reset deletes all absolute encoder data the encoder must be re-adjusted
after memory reset.
Data retained during memory reset
The following data is retained during memory reset:
●
TCP/IP and DP parameters
●
Diagnostics buffer
●
Data that was saved with the _savePersistentMemoryData, _saveUnitDataSet or
_exportUnitDataSet commands and with the "Copy RAM to ROM" function.
The data contents of a backup file generated by executing _savePersistentMemoryData
(PMEMORY.XML/PMEMORY.BAK) is written back to non-volatile data after 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
The technology packages and user data (configuration data, programs, parameter
assignments) you previously backed up to a CompactFlash Card by means of the "Copy
RAM to ROM" command are transferred to the "non-volatile data" area of the SIMOTION
410 during the next startup. This operation transfers any configuration data found on the
CompactFlash Card to the SIMOTION device after memory reset.
Memory reset by means of SIMOTION SCOUT
You can only reset memory using SIMOTION SCOUT if SIMOTION D410 is operating in
online mode.
1.
Select SIMOTION D410 from the Project Navigator of SIMOTION SCOUT.
2.
Select the "Target device" > "Operating mode" command from the context menu in order
to open the "D410: System Mode" dialog box.
3.
Select the STOP mode.
4.
Next, select the MRES mode to reset the memory.
