The non-volatile data of the SIMOTION D410‑2 has the following properties:
Table 5-2
Non-volatile data and real-time clock properties
Characteristics Non‑volatile data Real-time clock (RTC)
Location Non-volatile data are located in the
NVRAM of the SIMOTION D410-2.
The real-time clock is backed up
maintenance-free via a SuperCap.
Back-up battery No No
Backup time There is no maximum backup time At least 5 days
If the buffer time is exceeded on the real-time clock, the time is reset.
CompactFlash card
With the _savePersistentMemoryData system function, the user program can back up the
contents of the non‑volatile SIMOTION data to the CF card. This ensures that the retain
variables and the absolute encoder position are backed up in the event that a spare part is
used.
For the SINAMICS Integrated and SINAMICS S120 CU310-2/CU320-2, the non-volatile
SINAMICS data (NVRAM data) is backed up by setting the CU parameter p7775 to 1.
Note
IP and DP parameters in the non-volatile data
If
the CF card contains a configuration, the IP and DP parameters are loaded from the CF card
during power-up and used by the SIMOTION device. The SIMOTION D410‑2 uses the
addresses defined in these parameters to go online. During power-up, the IP and DP
parameters on the CF card are also written to the non‑volatile data. If the SIMOTION device
is then powered up with a CF card with no configuration, the IP and DP parameters are retained
in the non‑volatile data and are used by the device. 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.
The CF card contains the following data:
● SIMOTION Kernel (SIMOTION D firmware)
● Technology packages (TP)
● User data (units, configuration data, parameter settings, task configuration)
● IP parameters (IP address, subnet mask, router address)
● DP parameters (PROFIBUS DP address, baud rate)
It may also contain:
● User data saved with _savePersistentMemoryData and _export/_saveUnitDataSet
● Non-volatile SINAMICS data (NVRAM data) of the SINAMICS Integrated backed up with
CU parameter p7775 = 1
